Canola (Brassica napus L. and B. rapa L. [Brassicales: Brassicaceae]) is a major oilseed crop grown globally as a source of vegetable oil, animal feed and biofuel feedstock. The global demand for canola oil as a biofuel feedstock has increased due to recent regulations in the European Union, United States, and Canada. In North America, canola production is centered on the northern Great Plains where it is challenged by two highly destructive flea beetle species, the crucifer (Phyllotreta cruciferae Goeze, 1777) and the striped (Phyllotreta striolata Fabricius, 1803) flea beetles. In the spring, adult P. cruciferae and P. striolata begin feeding on canola seedlings, creating a 'shot hole' appearance, which can reduce the plant's photosynthetic capacity leading to uneven plant emergence and growth, reduced plant stand density, and reduced seed yield. Losses resulting from flea beetles are estimated in the tens of millions of dollars annually. At present, the principle means for flea beetle control are insecticides applied as systemic seed treatments and/or subsequent foliar sprays. The continued use of these products is being questioned due to environmental concerns and acquisition of resistance. As such, significant research effort is being directed toward the development of an integrated pest management system for these abundant and hard to manage pests of canola. Here, we review the ecology, pest status, and management of flea beetles in North America and discuss future research needed to promote flea beetle management and sustainable canola production.

The northern corn rootworm, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae) is a major pest of maize in the United States Corn Belt. Recently, resistance to Bacillus thuringiensis (Bt) maize was reported in North Dakota and increased use of Bt maize hybrids could facilitate resistance evolution in other maize-producing states. In this study, susceptibility to Bt proteins was evaluated in wild D. barberi populations from 8 fields collected in 5 different states (Minnesota, Missouri, Nebraska, Iowa, and North Dakota). Field populations were compared to a susceptible D. barberi colony in seedling and diet toxicity assays conducted with 3 concentrations of Cry3Bb1 (0.4, 4.0, and 40.0 µg/cm
2 ) and Gpp34/Tpp35Ab1 (previously called Cry34/35Ab1; 1.4, 14.0, and 140.0 µg/cm2 ). The 2019 population from Meeker Co., Minnesota (MN-2019), exhibited the lowest mortality to Cry3Bb1 and also had nominally lowest mortality to Gpp34/Tpp35Ab1 at the highest concentrations tested in diet toxicity assays. Percent second instar was also highest for larvae of the Minnesota population surviving Cry3Bb1. In seedling assays, MN and IA-2018 populations exhibited the highest proportion survival and dry weight to both proteins expressed in corn. No significant differences in mortality, percent second instar, and dry weight were observed at the highest concentration for both proteins among the populations collected in in 2020. Most D. barberi populations were still highly susceptible to Cry3Bb1 and Gpp34/Tpp35Ab1 proteins based on diet and seedling assays, but resistance appears to be developing in some D. barberi populations. Now that methods are available, resistance monitoring may also be needed for D. barberi in some regions. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Flea beetles (Coleoptera: Chrysomelidae) of the genus Phyllotreta are major pests of cole crops, canola, and related crops in the mustard family (Brassicaceae). Adults may damage seedlings or larger crop plants, impairing crop growth, rendering crops unmarketable, or killing seedlings outright. The two major North American crucifer pest species, Phyllotreta striolata (F.) and Phyllotreta cruciferae (Goeze), have male-produced pheromones attractive to both female and male adults. We tested the racemic synthetic pheromones, himachaladiene and hydroxyhimachalanone, as well as the host-plant-produced allyl isothiocyanate, alone and in combination, with experimental trapping in Maryland, Virginia, and North Dakota, using clear and yellow sticky traps and the ground-based 'rocket' trap (modified from boll weevil trap). Phyllotreta striolata was consistently attracted to the hydroxyketone, and captures were often enhanced by allyl isothiocyanate (AITC), but its response to pheromones, AITC, and trap color were variable from state to state. Phyllotreta cruciferae was strongly attracted to AITC, but its response to pheromone components varied by state, and this species was found rarely at the Maryland site. Phyllotreta bipustulata (F.) was attracted to the diene component, a new finding for this species. Several other genera of flea beetles were captured, some showing response to the semiochemicals and/or color. Results will be helpful in monitoring and possibly population suppression; however, further research is necessary to develop more efficient syntheses, optimal lure loadings, combinations, and controlled release methods.

- Abstract
The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) is a serious pest of the soybean plant, Glycine max, a major world-wide agricultural crop. We assembled a de novo genome sequence of Ap. glycines Biotype 1, from a culture established shortly after this species invaded North America. 20.4% of the Ap. glycines proteome is duplicated. These in-paralogs are enriched with Gene Ontology (GO) categories mostly related to apoptosis, a possible adaptation to plant chemistry and other environmental stressors. Approximately one-third of these genes show parallel duplication in other aphids. But Ap. gossypii, its closest related species, has the lowest number of these duplicated genes. An Illumina GoldenGate assay of 2380 SNPs was used to determine the world-wide population structure of Ap. Glycines. China and South Korean aphids are the closest to those in North America. China is the likely origin of other Asian aphid populations. The most distantly related aphids to those in North America are from Australia. The diversity of Ap. glycines in North America has decreased over time since its arrival. The genetic diversity of Ap. glycines North American population sampled shortly after its first detection in 2001 up to 2012 does not appear to correlate with geography. However, aphids collected on soybean Rag experimental varieties in Minnesota (MN), Iowa (IA), and Wisconsin (WI), closer to high density Rhamnus cathartica stands, appear to have higher capacity to colonize resistant soybean plants than aphids sampled in Ohio (OH), North Dakota (ND), and South Dakota (SD). Samples from the former states have SNP alleles with high FST values and frequencies, that overlap with genes involved in iron metabolism, a crucial metabolic pathway that may be affected by the Rag-associated soybean plant response. The Ap. glycines Biotype 1 genome will provide needed information for future analyses of mechanisms of aphid virulence and pesticide resistance as well as facilitate c

Bees are declining in the U.S., especially in heavily cropped landscapes due to habitat loss, pesticide use, and other factors. In Midwestern states like North Dakota (ND), where field crops are grown extensively, native resources for bees are often sparse. Soybean and sunflower are two major crops grown in ND which could provide floral resources for bee communities. To address the importance of these crops for bees, we sampled soybean and sunflower fields in 2018 using bee bowls. Our objectives were: 1) to determine the community composition, abundance, and species richness of bees in flowering soybean and sunflower grown in southeastern ND; 2) to determine the bee abundance at different flowering stages of each crop; and 3) to evaluate the effectiveness of bowl colors for monitoring bees. We collected a total of 3,038 bees and 53 different species. Apidae was the most common bee trapped across both crops with 82.4% of collected bees. Overall, community composition, abundance, and species richness of bees were not significantly different between crops; however, abundance indicated that 116.8% more bees were collected in soybean than sunflower. Regardless of crop, bee abundance at field edges was 18.2% higher than those captured from field interiors; however, species richness did not differ between field edges and interiors. Bee abundance did not differ across flowering stages of either crop, with one exception in sunflowers. Sunflower at R6 (flowering completed) had much higher bee abundance than sunflower at R5.5 (mid-flowering), probably due to the bowls being more attractive and visible as flowering ended. Blue bowls captured the majority of bees. Both blue and yellow bowls captured significantly more bees than white and red bowls across both crops. The relative bee diversity and abundance identified in this study increased our knowledge of bee communities in soybean and sunflower grown in ND. [ABSTRACT FROM AUTHOR]

- Abstract
Flea beetles (Coleoptera: Chrysomelidae) of the genus Phyllotretaare major pests of cole crops, canola, and related crops in the mustard family (Brassicaceae). Adults may damage seedlings or larger crop plants, impairing crop growth, rendering crops unmarketable, or killing seedlings outright. The two major North American crucifer pest species, Phyllotreta striolata(F.) and Phyllotreta cruciferae(Goeze), have male-produced pheromones attractive to both female and male adults. We tested the racemic synthetic pheromones, himachaladiene and hydroxyhimachalanone, as well as the host-plant-produced allyl isothiocyanate, alone and in combination, with experimental trapping in Maryland, Virginia, and North Dakota, using clear and yellow sticky traps and the ground-based ‘rocket’ trap (modified from boll weevil trap). Phyllotreta striolatawas consistently attracted to the hydroxyketone, and captures were often enhanced by allyl isothiocyanate (AITC), but its response to pheromones, AITC, and trap color were variable from state to state. Phyllotreta cruciferaewas strongly attracted to AITC, but its response to pheromone components varied by state, and this species was found rarely at the Maryland site. Phyllotreta bipustulata(F.) was attracted to the diene component, a new finding for this species. Several other genera of flea beetles were captured, some showing response to the semiochemicals and/or color. Results will be helpful in monitoring and possibly population suppression; however, further research is necessary to develop more efficient syntheses, optimal lure loadings, combinations, and controlled release methods.

Readily separated from its congener, by the sharp and projecting cephalic spines, by the more elevated and spiny paranota, by the variegated color of the hemelytra, and by spines along the lateral margins. Material examined. Type material examined: HolotypeƋ: Peru: Sullena, May, 10, 1942, E. J. Hambleton (USNM). Allotype♀: Sullena, May, 10, 1942, E. J. Hambleton (USNM). (Figure 1).

Ojeda and Neciosup (1974) listed many host plant records for different tingid species found in Peru, but they did not list any host plants for A. senta. Drake and Hambleton (1941) stated that this species had been taken on a woody shrub, but they did not provide any specific information. Comments. In their original description, Drake and Ruhoff (1960b) inadvertently switched the captions of figure 1 and figure 2; they corrected this error later that same year (Drake and Ruhoff, 1960c).

Dictyla ainslei: Drake and Ruhoff 1960a: 50 –51; Drake and Ruhoff 1965: 181. Diagnosis. Ambotingis ainslei can be separated from A. senta by the blunt, suberect cephalic spines, by the less elevated paranota with few spines, by the posteriorly incomplete median carina, by the tan or cream-colored dorsum, and by the long and ovate hemelytra that lack spines along the lateral margins. Redescription. General appearance ovate, tan to cream colored with a few fuscous markings, thorax and abdomen testaceous. Head testaceous, armed with five long, cream-colored, suberect, blunt spines, occipital pair slightly divergent, clypeal pair converging. Head short, slightly expanded beyond eyes. Bucculae closed anteriorly, produced slightly beyond apex of head. Antennae slender, segment one about as long as wide, fuscous; segment two, twice as long as wide, narrower than segment one, dark reddish brown; segment three long, cream colored, indistinctly pubescent with small white hairs; segment four slightly stout, about as long as segments one and two taken together, apex fuscous, armed with long, fine, white hairs. Antenniferous tubercles obsolete, modified into areolate flaps on bucculae. Bucculae triseriate, terminating on anterior margin of prosternum. Rostrum nearly extending to metasternum. Rostral groove welldeveloped, shallow on prosternum, deep on mesosternum, pro- and mesosternal laminae subparallel, metasternal laminae widely diverging.

- Abstract
In New York state, there are three races of European corn borer moths, which are characterized principally by differences in voltinism and the sex pheromone communication system. One race is bivoltine, with females producing and males responding to a 99:1 E/Z isomeric ratio of ∆11-14:0Ac's as the sex pheromone. Two races, one univoltine and one bivoltine, produce and respond to a 3:97 E/Z blend of ∆11-14:OAc's. The races are referred to as BE, UZ, and BZ to denote these differences. Analyses by gas chromatography of field-collected females indicate that there is significant hybridization between the Z and E races when in sympatry, with hybrid females producing a 68:32 ratio of E/Z11-14:OAc. Gene flow among the races was investigated using differences in triose phosphate isomerase (TPI) allozyme frequencies of moths from sites sampled across the state. The fixed nature of the Tpi-1 allele in the BE race and increases in the Tpi-1 allele frequencies in UZ populations in sympatry with the BE race support the hypothesis that gene flow following hybridization is unidirectional from BE populations into the Z populations. In addition, the TPI genotypes of the 10 hybrid females analyzed were consistent with hybridization occurring by E males mating with Z females
