Sleep is defined as unconsciousness from which the person can be aroused by sensory or other stimuli. Long-term consequences of sleep deprivation increased the risk of hypertension, diabetes mellitus, obesity, heart failure, stroke, memory impairment as well as depression. Obesity is one of the factors that affect sleep quality. Obesity is associated with sleep quality through its effect of causing obstructive sleep apneu (OSA), increased proinflammatory cytokins and gastrointestinal disorders. This study aims to analyze the correlation between body mass index and waist circumference with the quality of sleep of the pre-clinical students of the Mulawarman University, Faculty of Medicine. This research is an observational analytic study with a cross-sectional approach. Sleep quality data were collected using the PSQI questionare while body mass index and waist circumference data were collected by measuring body height using microtoise, body weight using a weighing scale and waist circumference using an anthropometric band. The result showed that 81.2% of respondents had poor sleep quality, 28.2% of respondents with obesity category and 35.9% of respondents who had central obesity. The result of hypothesis testing using chi square showed that both body mass index and waist curcumference had a significant relationship with sleep quality (p=0.046 and p=0.027).

The present study investigates the effect of parametric variations on microstructural and mechanical properties of friction stir welded (FSW) 6 mm thick as-cast AA6061/SiC Aluminum Matrix Composite (AMC) joints. The study has been designed by varying the traverse speed, tool rotational speed and tilt angle up to various levels. Microstructural investigations of welded samples were performed using low-resolution Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM). Energy-dispersive X-ray spectroscopy (EDS) is conducted to analyze the chemical composition and reinforcement distribution. To see the effect of parametric variation on mechanical property of the joint, ultimate tensile strength (UTS), percentage (%) elongation and hardness are investigated to support the study. As the optimum parametric values were somewhere missing in context to FSW of AMCs therefore present study deals with carefully deriving optimum weld parameters contributing to both sound weld as well as mechanical properties of the welded specimen. Tool tilt angle played a major role in determining the UTS of the welded specimen besides the tool rotational speed and welding speed making it one of the critical parameter for deciding mechanical properties of the welded specimen.

Insomnia is difficulty starting or maintaining sleep. There are several factors that are considered to be able to trigger and perpetuate insomnia, one of which is the sleep hygiene, which is included in the moderation factor. However, there is some controversy regarding the involvement of insufficient sleep hygiene towards insomnia. This study aims to determine the effect of sleep hygiene attitudes on the incidence of insomnia and a description of the incidence of insomnia and sleep hygiene in Mulawarman University students. The design of this study was observational analytic with a cross-sectional method, which consisted of 140 Mulawarman University students from 14 faculties. The sampling technique used is consecutive sampling. The data taken is primary data in 14 faculties of Mulawarman University. The research instrument used was the Insomnia Rating Scale questionnaire from the Kelompok Studi Psikiatri Biologi Jakarta and the Sleep Hygiene Index. The results of the study used the Chi-Square test and the Kolmogorov-Smirnov test obtained p value> 0.005. Based on the degree of insomnia, found 65% of respondents suffer from mild insomnia. The frequency of the sexes of women who suffer from insomnia more than men. Based on the degree of sleep hygiene attitudes, it was found that 78.6% of respondents had moderate sleep hygiene attitudes. This study concluded that there was no effect of sleep hygiene attitudes on the incidence of insomnia in Mulawarman University students.

According to Bacetti (1998) tooth rotation is defined as observable mesiolingual or distolingual intra-alveolar displacement of the tooth around its longitudinal axis.1 Tooth rotations cause difficulty in finishing fixed orthodontic treatment. In Begg’s technique rotation springs are used to correct tooth rotations. These springs are engaged into the vertical slot of the bracket. In case of preadjusted edgewise technique and edgewise technique brackets doesn’t have a vertical slot. So alternative methods are used to correct tooth rotations.2 Various methods include engaging NiTi arch wire into the bracket slot, off centering the bracket, using rotation wedges, creating a couple on the rotated tooth, by using ligature ties.3 The purpose of this case series is to discuss the biomechanics involved in rotation correction using bracket offsetting and couple. Keywords: Couple, Bracket offsetting.

OpenACC is a high-level directive-based parallel programming model that can manage the sophistication of heterogeneity in architectures and abstract it from the users. The portability of the model across CPUs and accelerators has gained the model a wide variety of users. This means it is also crucial to analyze the reliability of the compilers' implementations. To address this challenge, the OpenACC Validation and Verification team has proposed a validation testsuite to verify the OpenACC implementations across various compilers with an infrastructure for a more streamlined execution. This paper will cover the following aspects: (a) the new developments since the last publication on the testsuite, (b) outline the use of the infrastructure, (c) discuss tests that highlight our workflow process, (d) analyze the results from executing the testsuite on various systems, and (e) outline future developments.

Bromelain is a major proteolytic enzyme that existed in pineapple core and is widely known for its rich bioactivities, including anti-inflammatory and anti-bacterial. In this research, the isolation, extraction, and purification of bromelain from pineapple core was successfully performed, followed by the formulation of bromelain nanoemulsion, which ended with the in vitro testing on mouse skin to determine its skin permeability. The bromelain activity was also evaluated in this study, whereas the specific activity was determined at 51.36 U/mg and 68.62 U/mg at pineapple core and crude enzyme fractions, respectively. Moreover, the further fractionation using (NH4)2SO4 was performed and resulted in the specific activities of 118.48 U/mg for fraction 0-50% at 12 hr. In addition, three formulas of bromelain nanoemulsion were created in this study and characterized further using organoleptic and in vitro tests. According to the PSA data, the Formula 3 nanoemulsion, which majorly comprised of Tween 80 and small amounts of lecithin, shown a smaller droplet size at 22.04 nm, which corresponds to its higher penetration rate at 587.56 µg/cm2 in 30 minutes. Moreover, the decreased bromelain proteolytic activity in Formula 3 was not significant compared to the other two formulas. Thus, this optimized bromelain nanoemulsion formula can be studied further to examine its anti-bacterial potency through additional in vitro and in vivo tests.

Root weevils in the genus Otiorhynchus are an important pest in the nursery and small fruit production worldwide. The night-activity of the adult weevils obstruct timely monitoring and oviposition often starts before effective control measures are taken. The primary objective of this research goal was to develop an effective trap for monitoring that can be used in conjunction with the kairomone (Z)-2-pentenol and an effective means to kill the insects that enter the trap. A novel ruffle refuge trap (WeevilGrip) caught on average 4 to 5 times more weevils than a grooved board refuge in a field trial. Addition of the kairomone to the WeevilGrip further increased catches 52%. Linseed oil increased mortality to 59% and addition of Botanigard (ai Beauveria bassiana, strain GHA, Certis, BotaniGard WP 10–25%) increased mortality to 79%. The lure-refuge device consists of a flexible ruffle that can be wrapped around trees or placed on the soil within ground covers. This flexible shape maximizes contact with weevils compared to other available weevil trap designs. The WeevilGrip is an improved monitoring tool to support growers in integrated control strategies.

Since the arrival of Drosophila suzukii M. (Diptera: Drosophilidae), field applications of broad-spectrum insecticides have increased in berry crop production to protect susceptible fruits from infestation. Field studies were conducted from 2011 to 2013 to determine whether alternate row middle or border spray programs could manage D. suzukii as well as complete sprays and have less of an impact on non-target arthropods. Four raspberry sites and one blueberry site were alternate row middle and border sprayed, respectively. Adult and larva counts of D. suzukii were compared to conventional complete spray programs. Non-target arthropods were evaluated 7 d post-harvest. In both reduced spray trials, no differences in mean adult numbers and larvae of D. suzukii were detected between treatments. Mean counts immediately after sprays (i.e. 3–12 d after treatment) were also similar in complete and alternate row sprays. Both reduced spray strategies had significantly more Stethorus spp.; additionally, alternate row sprays had significantly more Psyllobora spp. These reduced pesticide strategies are additional tools to consider in D. suzukii IPM programs that can reduce the area sprayed, application time, and input costs while conserving natural enemies.

The yeast Candida parapsilosis is an increasingly common cause of systemic fungal infections among immunocompromised individuals, including premature infants. Adhesion to host surfaces is an important step in pathogenesis, but this process has not been extensively studied in this organism. A microfluidics assay was developed to test the ability of C. parapsilosis to adhere to immobilized host extracellular matrix proteins under physiological fluid shear conditions. Growth in mammalian tissue culture medium at 37°C for 3 to 6 h led to the induction of an adhesive phenotype at shear forces of 1 to 5 dynes/cm 2 in some isolates of C. parapsilosis . Glutamic acid, proline, and calcium appeared to be the minimally necessary requirements for increased adhesion in these assays. To determine whether genes homologous to the ALS gene family of C. albicans were important for the adhesive phenotype, the expression levels of 5 homologous C. parapsilosis genes were quantified by using quantitative PCR (qPCR) under conditions leading to increased adhesion. CPAR2_404800 ( CpALS7 ) and CPAR2_404780 showed increased expression levels compared to those in control yeast. The extent of adhesion was variable among different isolates, and linear regression identified the expression of CpALS7 but not CPAR2_404780 as having a strong positive correlation with adhesion. A homozygous CpALS7 deletion strain was deficient in adhesion, whereas the expression of CpALS7 in Saccharomyces cerevisiae resulted in increased adhesion. Together, these data provide strong evidence that CpAls7 aids in the adherence of C. parapsilosis to the extracellular matrix under shear forces and support its previously reported role in virulence.

Drosophila suzukii (Matsumura) is an economic pest of small fruits and cherries that attacks intact ripening fruits. Host susceptibility may be influenced by characteristics such as flesh firmness, penetration force of the skin, total soluble solids (TSS, also known as °Brix), and pH. Improved knowledge of factors affecting fruit susceptibility is needed for developing thresholds and risk prediction models for IPM. A combination of laboratory and field studies was conducted to develop prediction and potential management tools. First, a direct bioassay was used to calculate the probability of oviposition in a given fruit based on various characteristics as determined across laboratory and field trials in Oregon and North Carolina, US. When multiple characteristics were evaluated simultaneously, oviposition probability consistently increased as penetration force decreased and pH increased. Oviposition probability sometimes increased as TSS increased. Second, raspberries and blueberries in unsprayed fields had substantially lower infestation in ripening fruit compared to ripe fruit. There was no or minimal infestation in green fruit. Third, given that skin penetration force influences oviposition, practices used to improve fruit quality were examined in laboratory no-choice cages for potential reduction of oviposition. Blueberry fruit sprayed with calcium silicate in the field had greater penetration force and firmness and reduced number of eggs laid by D. suzukii compared to untreated fruit. Other calcium-based treatments increased Ca content and firmness of fruit relative to untreated fruit. Timing of insecticide spray for D. suzukii might be delayed until fruit become susceptible.

Spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), may utilize wild ‘Himalaya’ blackberry (HB) Rubus armeniacus Focke or other non-crop plants as refugia and possibly exploit adjacent field margins before colonizing cultivated fruiting crops. Studies were conducted to determine the role of field margins containing HB and their effect on D. suzukii activity, density and distribution in an adjacent commercial red raspberry crop. One-ha plots adjacent to field margins containing HB or known non-host (NH) grass crops were established in 2011 and 2012 and replicated three times. Each plot contained two transects with monitoring traps for D. suzukii in the field margin (0 m) and spaced approximately 10 (crop boundary), 40, 70 and 100 m into the adjacent crop (n = 10 traps/plot). Field margin vegetation was treated with a 10% chicken egg white mark solution weekly from pre-harvest until the end of harvest using a cannon sprayer. Adult D. suzukii were collected from traps weekly and analysed for the presence of the egg white mark using an egg white-specific enzyme-linked immunosorbent assay (ELISA). During both years, marked flies and total flies were captured in higher numbers in HB field margins, whereas virtually no flies were captured in field margins containing no known alternative host. Similarly, more flies were captured in the crop near HB than near NH. Spatial Analysis by Distance IndicEs (SADIE) and mean D. suzukii trap captures additionally displayed significantly higher fly densities in the raspberry field near HB than near NH. These results suggest that HB may contribute to elevated D. suzukii populations and pest pressure in comparison with field margins containing no known alternate host vegetation for D. suzukii. Having closely adjacent non-crop alternate host landscapes may result in increased D. suzukii pest pressure.

Drosophila suzukii Matsumura (Diptera: Drosophilidae) has caused significant economic damage to berry and stone fruit production regions. Markers that are systemic in plants and easily transferred to target organisms are needed to track D. suzukii exploitation of host resources and trophic interactions. High and low concentrations of the trace element, rubidium (Rb), and the stable isotope, 15N, were tested to mark D. suzukii larvae feeding on fruits of enriched strawberry plants grown in containers under greenhouse conditions. Fly marker content and proportion of flies marked 1, 7, and 14 d after emergence from enriched fruits and fly dry mass were analyzed. Nearly 100% of the flies analyzed 14 d after emerging from 15N-enriched plants were marked, whereas only 30-75% and 0-3% were marked 14 d after emerging from high and low Rb concentration plants, respectively. Rapid Rb decay, strong 15N persistence, and the economics of using these markers in the field to elucidate D. suzukii pest ecology are discussed.

Background Urinalysis data in preclinical toxicology studies can be influenced by preanalytic and analytic factors which have the potential to confound interpretation. There is a paucity of information regarding positive reagent strip urinary blood reactions in healthy nonhuman primates (NHP) and Beagle dogs used in preclinical toxicology studies. Objectives The objectives were (1) to establish historical control data for reagent strip urinary blood reactions in healthy NHP and Beagle dogs, (2) to determine the incidence of positive urinary blood reactions during predose and dosing phases, and (3) to determine if collection practice was a relevant parameter. Methods Historical control data from 2 institutions in the biopharmaceutical industry were retrospectively analyzed for reagent strip urinary blood reactions in healthy NHP and Beagles. The incidence of positive results between the 2 institutions with different urine collection practices and between males and females was compared. Results The incidence of positive urinary blood reactions in NHP was comparable between institutions (≤ 14% in males; ≤ 33% in females), while the incidence of positive urinary blood reactions in Beagles was more variable (≤ 77% in males; ≤ 69% in females), and higher in females during the dosing phase. Conclusions Positive urinary blood results that could potentially be misinterpreted as toxicologically relevant were identified in healthy NHP and Beagles during predose and dosing phases. Different incidences of positive results between the 2 institutions were likely related to collection practices. Strategies to reduce feces and food contamination of collected urine samples should help minimize false-positive urinary blood reactions.

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a pest of small fruits and cherries, and has also been noted to infest a variety of wild, ornamental, and uncultivated hosts. Identify- ing alternative hosts is critical for pest management. Research objectives were to: 1) survey fruits in the field for natural infestation of D. suzukii, 2) determine the susceptibility of fruits in laboratory no-choice studies, and 3) evaluate short-range preference between simultaneously ripe alternative hosts and culti- vated fruits in laboratory choice studies. Field surveys identified new hosts or confirmed previously re- ported hosts including: Berberis aquifolium Pursh, Oregon grape; Cornus spp., dogwood; Cotoneaster lacteus W.W. Smith, milkflower cotoneaster; Elaeagnus umbellata Thunberg, Autumn olive; Frangula purshiana (de Candolle) A. Gray, cascara buckthorn; Lindera benzoin (L.) Blume, spicebush; Lonicera caerulea L., blue honeysuckle; Morus sp., mulberry; Phytolacca americana L., pokeweed; Prunus avium (L.) L., wild cherry;Prunus laurocerasus L., cherry laurel;Prunus lusitanica L., Portuguese laurel;Rubus armeniacus Focke, Himalaya blackberry; Rubus spectabilis Pursh, salmonberry; Sambucus nigra L., black elderberry; Sarcococca confusa Sealy, sweet box; Solanum dulcamara L., bittersweet nightshade; andSymphoricarpos albus (L.) S.F. Blake, snowberry. High fruit infestations were observed in S. confusa during April-May and Lonicera spp. in June before most commercial fruits ripen. From both field and laboratory studies, there was no evidence of susceptibility during the estimated ripe period Crataegus L. 'Autumn Glory,' hawthorn; Ilex crenata Thunberg, Japanese holly; Nandina domestica Thunberg, sacred bamboo; Rhaphiolepis umbellata (Thunberg) Makino, yeddo hawthorne; Rosa acicularis Lindley, prickly rose; Skimmia japonica Thunberg, Japanese skimmia; and Viburnum davidii Franchet, David's vibur- num. Lastly, laboratory choice tests identified that several fall-ripening alternative hosts were more sus- ceptible than 'Pinot noir' or 'Pinot gris' wine grapes. By understanding host use, growers can identify high-risk areas where coordinated action may reduce infestation ofD. suzukii in crops.

The recent arrival of Drosophila suzukii, an invasive pest of soft-skinned fruit with a wide host range, has resulted in increased production costs for growers and the need for additional insecticide applications each growing season. There are few effective organic insecticides for D. suzukii, and insecticide use in conventional farms may be disruptive to natural enemies, suggesting a need for effective biological control to combat D. suzukii. Commercially available natural enemies were evaluated for their potential use in augmentative releases, including: the predators Orius insidiosus and Dalotia coriaria; the entomopathogenic fungi Metarhizium anisopliae, Beauveria bassiana and Paecilomyces fumosoroseus; and the entomopathogenic nematodes Heterorhabditis bacteriophora, Steinernema feltiae and S. carpocapsae. This suite of natural enemies was chosen to target D. suzukii adults as well as larvae in hanging or dropped fruit. Of the cultured fungal strains tested, only M. anisopliae significantly decreased D. suzukii survival, but it had low residual activity and no effect on D. suzukii fecundity. O. insidiosus decreased D. suzukii survival in simple laboratory arenas but not on potted blueberries or bagged blueberry branches outdoors. D. coriaria did not decrease D. suzukii survival in infested blueberries in simple laboratory arenas. The nematodes tested showed low infection rates and were not able to affect D. suzukii survival. Although this suite of natural enemies showed limited ability to suppress D. suzukii under the tested conditions, these and related natural enemies are present as part of the endemic natural enemy community in agricultural fields, where they may contribute to D. suzukii suppression.

La septotomía se realizó utilizando videoendoscopio flexible, esfinterótomo aguja, electrobisturi para DSE tipo Hibridknife, mediante una técnica ya estandarizada. Resultados: Se trataron 25 pacientes con edad promedio de 71 años (rango etario de 45 a 84 años). En una paciente su mejoría fue muy poca, por lo que se sometió a intervención quirúrgica, donde tampoco hubo resultados consistentes. Veintiún pacientes mostraron un alivio completo de la disfagia. Tres pacientes que tuvieron recurrencia sintomática fueron tratados con el mismo método endoscópico entre 2 y 4 sesiones evolucionando de forma satisfactoria. Conclusiones: La septotomía endoscópica del divertículo de Zenker es un método eficaz y seguro, por lo tanto representa una alternativa real a la cirugía. Introduction: Diverticulotomy or Endoscopic septotomy in Zenker's diverticulum is an alternative to others therapeutics approaches. The present study shows our experience of this endoscopic technique. Patients and methods: Retrospective analysis between 2009 and 2017 in patients with Zenker's diverticulum. The procedure was performed using a flexible video endoscope and a needle knife, Erbe hybrid knife probe, using an already standardized technique. Results: Twenty-five patients with an average age of 71 years (age range 45-84 years) were treated. In one patient his improvement was very little, therefore surgical procedure was performed, nevertheless this procedure had not consistent results. Twenty-one patients showed complete relief of dysphagia. Three patients who had symptomatically relapsed were retreated with the same endoscopic method between 2 and 4 sessions with good results. Conclusions: Zenker's endoscopic septotomy of the diverticulum is an effective and safe method; thereby it represents a real alternative to surgical treatment.

Ornamental trees, shrubs, annuals, grasses, and other plants are cultivated and planted for aesthetic and utility purposes in urban landscapes, including yards, parks, gardens, sports fields, cemeteries, medians, and roadsides. Insecticides are widely used to control pests impacting these plants. Public concern about the adverse effects of chemical insecticides has created an environment in which biological, botanical, and less acutely toxic insecticides are regarded as desirable alternatives, especially to older insecticide active ingredients with unfavorable toxicology profiles. Several entomopathogens have been developed for managing pests in high-value ornamental crops. In this chapter we discuss prospects and progress that has been made with entomopathogens for managing pests of ornamental plants in the following groups: phytophageous mites, wood-boring beetles/caterpillars, root-feeding weevils, defoliating beetles/caterpillars, and sap-feeding insects, including aphids, whiteflies, and thrips.

Drosophila suzukii Matsumura (Diptera: Drosophilidae) utilizes ‘Himalaya’ blackberry, Rubus armeniacus Focke (Rosaceae), as a host and may invade berry and stone fruit crops from field margins containing this invasive weed. Laboratory and semi-field studies were conducted to determine (1) the persistence of protein marks including 10% chicken egg whites (egg albumin protein), 20% bovine milk (milk casein protein), and 20% soy milk (soy trypsin inhibitor protein) on topically sprayed D. suzukii, (2) protein retention on blackberry leaves, and (3) D. suzukii acquisition of protein afterexposureto markedblackberryleaves for upto 14 days afterapplication. Allflies and leaves wereassayedforthepresenceoftheproteinmarksusingprotein-specificenzyme-linkedimmunosorbent assays. Egg albumin, milk casein, and soy trypsin proteins persisted on 94, 49, and 25% of the topically marked D. suzukii, respectively, throughout the 14-day study period. Egg albumin was retained on 100% of treated leaves for 14 days, regardless of environmental conditions. At least 50% of flies exposed residually to egg albumin-treated leaves were marked for 3 days, regardless of exposure time and environmental conditions. However, increasing fly exposure time to treated leaves in April and June appeared to improve protein mark acquisition. Acquisition of protein by flies from treated leaves for milk casein was inconsistent, and poor for soy trypsin, despite detectable levels on treated leaves. Egg albumin had the longest and most consistent persistence on flies, leaves, and flies exposed to leaves in laboratory and semi-field studies, under a variety of environmental conditions andexposuretimes.

The Seville Limestone has been tentatively identified in southeast Kansas with only one outcrop. Cores recently drilled southwest of Pittsburg, Kansas, in relation to a new proposed highway alignment of US-69 have provided information on the occurrence and characteristics of the Seville Limestone. Detailed lithostratigraphic observations of the Seville Limestone Member presented within core samples increase understanding of the Seville Limestone Member lithostratigraphy. The Seville Limestone Member is continuous through southern Crawford County and into northern Cherokee County as a significant marker unit that distinguishes the boundary between the Cabaniss Formation and the Krebs Formation, both belonging to the Middle Pennsylvanian Cherokee Group. The Cabaniss Formation increases in thickness south into Cherokee County with increasing thickness of terrestrial sandstones and near shore marine shales occurring between the Weir-Pittsburg Coal (WPC) sequence and the Seville Limestone Member.

Environ. Entomol. 42(6): 1348Ð1355 (2013); DOI: http://dx.doi.org/10.1603/EN13148 ABSTRACT Drosophila suzukii (Matsumura), an invasive pest of small and stone fruits, has been recently detected in 39 states of the United States, Canada, Mexico, and Europe. This pest attacks ripening fruit, causing economic losses including increased management costs and crop rejection. Ongoing research aims to improve the efÞcacy of monitoring traps. Studies were conducted to evaluate how physical trap features affect captures ofD.suzukii. We evaluated Þve colors, two bait surface areas, and a top and side position for the sy entry point. Studies were conducted at 16 sites spanning seven states and provinces of North America and nine crop types. Apple cider vinegar was the standard bait in all trap types. In the overall analysis, yellow-colored traps caught signiÞcantly more sies than clear, white, and black traps; and red traps caught more than clear traps. Results by color may be insuenced by crop type. Overall, the trap with a greater bait surface area caught slightly more D. suzukii than the trap with smaller area (90 vs. 40 cm 2 ). Overall, the two traps with a side-mesh entry, with or without a protective rain tent, caught more D. suzukii than the trap with a top-mesh entry and tent.

Drosophila suzukii Matsumura (Diptera: Drosophilidae), a recent invasive pest of small and stone fruits, has been detected in more than half of the U.S. states, and in Canada, Mexico, and Europe. Upon discovery, several different trap designs were recommended for monitoring. This study compared the trap designs across seven states/provinces in North America and nine crop types. Between May and November 2011, we compared a clear cup with 10 side holes (clear); a commercial trap with two side holes (commercial); a Rubbermaid container with mesh lid and rain tent (Haviland), and with 10 side holes and no tent (modified Haviland); a red cup with 10 side holes (red); and a white container with mesh lid and rain tent (Van Steenwyk). Although fly catches among traps varied per site, overall, the Haviland trap caught the most D. suzukii, followed by the red, Van Steenwyk, and clear trap. The modified Haviland and commercial trap had low captures. Among five crop types in Oregon, a clear cup with mesh sid...

Black vine weevil (BVW), Otiorhynchus sulcatus (Coleoptera: Curculionidae, Fabricius), is a serious pest of cranberry, Vaccinium macrocarpon Ait. Larvae feed undetected within the soil and cause damage to roots and underground vines. We correlated damage caused by feeding larvae from known BVW egg densities. Two cultivars of potted cranberry vines, ‘Stevens’ and ‘McFarlin’, were inoculated with 0, 5, 10, 20, 40, and 80 eggs per pot. Root damage and canopy health were assessed. ‘Stevens’ exceeded ‘McFarlin’ in dry shoot weight, total shoot length, total leaf area, and dry root weight before egg treatments. Damage to underground vines increased with increasing egg density and more damage was found in ‘Stevens’ than ‘McFarlin’ at the highest egg densities. In August, plant water use and total shoot length in ‘McFarlin’ were significantly greater in plants treated with 0–5 eggs per pot compared with plants treated with 40–80 eggs per pot. The effect on total shoot length was more pronounced in October. ‘Stevens’ showed no response to increasing BVW density for up to 24 weeks. Destructive measurements showed decreased root weight in ‘McFarlin’ but not ‘Stevens’. Both cultivars showed a similar decrease in dry shoot weight, total shoot length, and percent green leaf area with increasing BVW egg density. Root damage increased as BVW egg density increased and this damage resulted in reduced plant water use for ‘McFarlin’. Reduced shoot growth and leaf area was recorded for both cultivars, although these effects were more apparent in ‘McFarlin’ and at an earlier stage than in ‘Stevens’.

Root weevils in the genus Otiorhynchus are cited as one of the most important pests in the major nursery and small fruit production areas throughout the United States, western Canada, and northern Europe. A major problem in combating weevil attack is monitoring and timing of control measures. Because of the night-activity of the adult weevils growers do not observe the emerging weevils in a timely manner and oviposition often starts before effective control measures are taken. Several vine weevil electroantennogram-active plant volatiles were identified from a preferred host plant, Euonymus fortunei. Main compounds evoking antennal responses on the weevils' antennae were (Z)-2-pentenol, (E)-2-hexenol, (Z)-3-hexenol, methyl benzoate, linalool, (E)-4,8-dimethyl-1,3,7-nonatriene, methyl eugenol, and (E, E)-alpha-farnesene. Several of these compounds were tested alone and in mixtures on attractiveness for the vine weevil Otiorhynchus sulcatus (F.) in field-grown strawberry in Oregon. O. sulcatus were attracted to (Z)-2-pentenol (approximately 3 x more than control) and a 1:1 ratio mixture of (Z)-2-pentenol and methyl eugenol (4.5 x more than control). This is the first report of field-active attractants for O. sulcatus which holds promise for the development of new monitoring strategies for growers in the near future.

BACKGROUND: The spotted wing Drosophila, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is an invasive pest of small-fruit crops. Unlike most other Drosophila, this insect is able to oviposit into and damage ripe and ripening fruit, making it unmarketable. Because this is a new pest in the United States, it is necessary to identify registered insecticides to manage this insect effectively in conventional and organic production systems. RESULTS: The present laboratory bioassays and field trials identified a number of insecticides representing various modes of action that are effective in controlling D. suzukii. Products that performed well in the laboratory bioassay also performed well in the field, indicating that screening of new chemistries in the laboratory is a worthy exercise. Field application of pyrethoids, organophosphates or spinosyns provided 5–14 days of residual control of D. suzukii. The efficacy of the neonicotinoids as adulticides was not satisfactory compared with the other contact-mode-of-action chemistries. Based on the zero tolerance by the small-fruit industry and the individual effects mentioned above, neonicotinoids are not currently recommended for D. suzukii management. CONCLUSIONS: There are effective insecticides registered for controlling D. suzukii infestations in susceptible small-fruit crops. Copyright © 2011 Society of Chemical Industry

Spotted wing drosophila, Drosophila suzukii Matsumura, a native of eastern and southeastern Asia, is a pest of small and stone fruits. First detected in California in 2008, the insect is now found across the Pacific Coast states. Its penchant for attacking healthy, ripening fruit (as opposed to overripe and rotting fruit favored by other so-called “vinegar flies”) makes it a potential economic threat to a host of soft- and thin-skinned fruit crops including cherry, raspberry, blackberry, blueberry, strawberry, peach, plums, pluots, nectarines, juice grape, table grape, and wine grape. Coordinated research projects to determine host preference, seasonal phenology, biology, and management options are taking place among entomologists in Washington, Oregon, and California. A description of the pest and initial findings on its biology, life history, known and expected geographic range, management and monitoring techniques, and economic considerations are presented and discussed.

Filbertworm, Cydia latiferreana (Walsingham) (Lepidoptera: Tortricidae), is a key insect pest associated with hazelnuts, Corylus avellana L. (Fagales: Betulaceae), in North America. This study investigated the feasibility of entomopathogenic nematodes as an alternative strategy for filbertworm control. Laboratory and field experiments were conducted between October 2007 and May 2008 in Benton County, OR, to evaluate the ability of the nematode Steinernema carpocapsae (Weiser) (Rhabditida: Steinernematidae) to infect filbertworm larvae and pupae. The susceptibility of larvae with and without hibernacula as well as pupae to S. carpocapsae was tested in laboratory bioassays using nematode concentrations between 40 and 200 infective juveniles (IJs) per cm2. Percentage of nematode infection was not significantly affected by the presence of hibernacula (infection range, 90–92%) compared with larvae without hibernacula (80–95%), or by pupal stage (50–75%) compared with larvae (65–75%). In additional field trials, the effect of nematode rate, water application rate, and orchard floor cover on nematode efficacy was determined in October 2007 and May/June 2008. Sentinel filbertworm larvae in plots with either bare soil or debris (leaves, twigs, husks, and blank nuts) were treated with S. carpocapsae at rates ranging from 40 to 150 IJs per cm2 applied in 75 or 190 ml/m2 water. Average filbertworm mortality ranged from 2 to 11% and from 50 to 78% in October and May, respectively. Larval mortality increased with increasing nematode concentration, but was not significantly affected by water application rate or orchard floor cover. Our experiments suggest that S. carpocapsae can play a role in the control of filbertworm larvae overwintering on the orchard floor.

The ecology of fungal entomopathogens in the rhizosphere is an understudied area of insect pathology. The rhizosphere is the region of soil in which the release of root exudates influences the soil microbiota, and may provide a favorable environment for fungal entomopathogens. The objective of this review is to bring together the relatively scant data available to date on the subject of fungal entomopathogens colonizing the rhizosphere and to highlight the importance of these findings. Gaining a better understanding of the ecology of fungal entomopathogens in the rhizosphere will help in the development of successful microbial control strategies against root-feeding insect pests.

Ostrinia nubilalis (Hubner) (Lepidoptera: Crambidae) is one of the most damaging insect pests of corn. Studies were conducted to determine whether live larval counts obtained from corn whorls were predictive of the amount of larval tunneling that would result in the stalk of the plant 40 d later at the end of larval development. Whorls from plants treated with Dipel 10G (6,400 IU per whorl) and untreated controls, both infested with O. nubilalis neonates, were evaluated for the number of live larvae in 50 whorls 5, 7, 9, and 12 d after Bacillus thuringiensis (Berliner) (Bacillales: Bacillaceae) application. Forty days after larval infestation, 25 plants from each plot were split from tassel to base, and the length of larval tunneling was recorded. There was a strong relationship between numbers of live larvae in the plant whorl and the length of larval tunneling that resulted. While linear at each location, there was significant variation in the relationship among locations, indicating that comparisons could not be made between years or locations within a year. Blocks within a location on a given year did not vary significantly and reproducible results were obtained each year within a given location as well as on any of the whorl pulling dates evaluated. Because of its ease of use, predictability, and rapid return of results, we propose this technique as an additional method to shot-hole feeding and stalk splitting to evaluate the effectiveness of O. nubilalis management strategies.

The entomopathogenic fungus Metarhizium anisopliae (Metchnikoff) Sorokin (Hypocreales: Clavicipitaceae) is registered in the United States and The Netherlands for black vine weevil, Otiorhynchus sulcatus (Coleoptera: Curculionidae) control in container-grown ornamentals. These studies were conducted to determine the compatibility of M. anisopliae (F52) with a wide range of fungicides commonly applied to container-grown ornamentals for the management of soil-borne plant pathogens. The impact of fungicides on spore germination and mycelial growth were determined in vitro. In addition, M. anisopliae persistence in bulk and rhizosphere soil was determined 30 days following dual application of each fungicide at 7–28 days intervals as prescribed. A number of fungicides (thiophanate-methyl, dimethomorph, captan, triflumizole, triflozystrobin, pyraclostrobin, azoxystrobin) inhibited spore germination in vitro. A larger number of fungicides (fosetyl-AI, thiophanate-methyl, dimethomorph, captan, quintozene, triflumizole, fludioxanil, triflozystrobin, pyraclostrobin, fludiox-mefanox, iprodione, azoxystrobin, phosphorus acid/K-salts) inhibited mycelial growth in vitro. Only three fungicides (etridiazole, propamocard and mafanoxam) had no significant impact in vitro on spore germination or mycelial growth. While a number of fungicides had a detrimental impact in vitro, there was no impact on M. anisopliae populations in bulk soil following dual application of any fungicide. However, the fungicides captan and triflumizolet, which have a short reapplication interval, had a detrimental impact on M. anisopliae populations in the rhizosphere. As researchers develop rhizosphere competence as an alternative management strategy for black vine weevil, the fungicides captan and triflumizole should be avoided.

Nosema pyrausta, an entomopathogenic microsporidium, is an important population regulator of the European corn borer, Ostrinia nubilalis. This manuscript is a review of research on the relationships between N. pyrausta and O. nubilalis. N. pyrausta was described from O. nubilalis in Hungary in 1927 and from O. nubilalis in IA in 1950. It affects the basic biology of O. nubilalis by slowing larval development, reducing percentage pupation, and decreasing adult longevity, oviposition and fecundity. Infections are maintained in a population by vertical and horizontal transmission. Success of vertical transmission depends on intensity of infection. Horizontal transmission is dependent on stage of larval development at time of infection, quantity of inoculum, and host density. Abiotic and biotic factors coupled with N. pyrausta usually have an additive effect in decreasing the fitness of O. nubilalis, i.e., cold temperatures reduce fecundity and increase larval mortality, host plant resistance reduces the number of larvae per plant. Also, microbial and chemical insecticides are more effective in reducing plant feeding if the insect is infected with N. pyrausta. Predators in general feed on N. pyrausta-infected O. nubilalis with no decrease in fitness. Parasitoids do coexist with N. pyrausta, however, parasitoid fecundity is usually reduced when developing in a N. pyrausta-infected host. Previously unreported data are presented on the prevalence of N. pyrausta in O. nubilalis populations from many parts of the US. These data demonstrate that N. pyrausta continues to be present and fluctuate in populations of O. nubilalis as it has since its discovery in the US. Also, the dynamics of its presence remain similar through changes in corn production including crop rotations, reduced tillage and transgenic insect-resistant varieties.
