The article discusses the discovery of genus Sigalphus during the 2007 expedition in Southern Vietnam. It mentions that the genus was closely related to northern distributed S. gyrodontus commonly known from southern China and northern Vietnam. It notes that Sigalphus is a small genus known from the Old World which occur in Southeast Asia.

The article discusses the discovery of genus Dinotrema on May 2013 at the barren sunny and open slope vegetation site in Finland with brachypterous males and macropterous females. It mentions that Dinotrema crassiceps is a type of species of genus Pterusa with unidentified opposite sex. It examines the genus Pterusa and determined that it cannot be retained as valid genus since female Dinotrema species has no submalar groove.

A modification of a DNA extraction method by freezing specimens is recognized as one of new non-destructive techniques. In this study, the freezing method has been applied on dried and fresh, tiny and economically important insect samples, i.e. on adults and larvae of wasps, fruit flies and thrips. The modification entails freezing instead of a lengthy incubation of the sample. Most importantly, the sample is not cut into small pieces, but is soaked in a lysis buffer and then frozen in -22°C for a minimum of 20 minutes. After that, the remaining protocols from the manual of DNeasy Blood and Tissue Kit are followed. Several other non-destructive methods also require incubation for at least 20 minutes in a lysis buffer at 55°C. However, the duration of that incubation process is not standard for all insect and arthropod species. This is because the optimization process is based on species size and the thickness of the insect cuticle. With the freezing method, samples are not damaged, and remain available for morphological re-examination. Hence, the sample can also be re-used for taxonomic work with no distortion of samples, no loss of coloration and no phenotypic changes on the external morphology. The complete protocol for the freezing method is described in this paper. With this freezing method, DNA concentration of 0.2- 5.61 ng/µl was recovered on various tiny insect species. Furthermore, several specimens of Bactrocera and Heratemis_species were selected as control specimens in analyzing a variety of extraction methods. The freezing method was proven as a new technique to obtain sufficient quantity and a high quality of DNA for molecular work. [ABSTRACT FROM AUTHOR]

Pseudorhaconotus enervatus gen. nov. & spec. nov. (Hymenoptera: Braconidae: Doryctinae) from Spain is described and illustrated. The new genus is similar to the genus Rhaconotus Ruthe, 1854, but differs by the lack of vein r-m of the fore wing and by the absence of dorsope on the first metasomal tergite.

Twenty-one species of the family Braconidae (Hymenoptera) are added to the checklist of Braconidae from Madeira, resulting in 113 species, of which 17 species are endemic to Madeira Islands and 4 species are only known from Madeira and Canary Islands. Five species are reported new for the Selvagens Islands. Five new species are described and illustrated: Homolobus (Apatia) madeirensis spec. nov.

The first reported parasitoid reared from Agrilus planipennis Fairmaire, Spathius agrili n. sp., is described from China. S. agrili was reared from A. planipennis in China attacking a Fraxinus species native to North America, Fraxinus velutina Torr., and one endemic to the region, Fraxinus mandshurica Rupr. Life history observations of S. agrili in the field and laboratory indicate it is a gregarious idiobiont ectoparasitoid and has up to four generations per year. Parasitism rates in the field ranged from 30 to 90%, with one to 35 S. agrili eggs associated with a single host. From a host larva 1-18 adult wasps (average of 8.4) were reared. Based on laboratory rearings, the emerging adult female to male ratio is 3:1. [ABSTRACT FROM AUTHOR]

Although individuals with poor food security might be expected to have reduced food intake, and thus reduced body fat and less likelihood of being overweight, these associations have not been adequately studied. The purpose of the current study was to examine the relationship between food insecurity and overweight as measured by body mass index (BMI) using data from the nationally representative 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII). Overweight was defined as BMI >27.3 kg/m(2) for women and 27.8 kg/m(2) for men. Food insecurity was related to overweight status for women (n = 4509, P < 0.0001), but not for men (n = 4970, P = 0.44). Excluding the 11 severely insecure women, the prevalence of overweight among women increased as food insecurity increased, from 34% for those who were food secure (n = 3447), to 41% for those who were mildly food insecure (n = 966) and to 52% for those who were moderately food insecure (n = 86). Food insecurity remained a significant predictor of overweight status, after adjustment for potentially confounding demographic and lifestyle variables (P < 0.01). In a logistic regression analysis, mildly insecure women were 30% more likely to be overweight than those who were food secure [odds ratio (OR) 1.3, P = 0.005]. Thus, food insecurity had an unexpected and paradoxical association with overweight status among women with a higher prevalence of overweight among the food insecure, and a resulting potential for increased incidence of obesity-related chronic diseases. Given that the rates of both overweight and food insecurity are on the rise, this research area warrants further investigation. [ABSTRACT FROM AUTHOR]

This study examined how altering text and graphics of a nutrition brochure could affect the ability to remember the content of the message. Two theoretical models were used to guide alterations: dual-coding theory and the communications model. Three brochure formats were tested: the original brochure containing abstract text and abstract graphics, a modified brochure with relatively concrete text and abstract graphics, and a relatively concrete text brochure with concrete graphics. Participants ( N = 239 women) were divided into four age groups: 20-30, 40-50, 60-70 and over 70 years. Women were randomly assigned into each of the three experimental brochure formats or a control group. Participants completed recalled materials from the assigned brochures (the no treatment control group did not include a brochure) at two different sessions, 30 days apart. Data were content analyzed and results were compared using analysis of covariance to test differences by age and brochure types. Younger women (20-30 and 40-50 years) recalled more information than women over 60 years. More concrete nutrition education print materials enhanced recall of information presented immediately after reading the material; however, this effect was transient and lasted less than 30 days after a one-time reading. The implications of these data for communicating nutrition messages with print materials are discussed. [ABSTRACT FROM AUTHOR]
