Alcohol use disorder (AUD) is a major health, social and economic problem for which there are few effective treatments. The opiate antagonist naltrexone is currently prescribed clinically with mixed success. We have used naltrexone in an established behavioral assay (CAFE) in Drosophila melanogaster that measures the flies' preference for ethanol-containing food. We have confirmed that Drosophi...
The pond wolf spider Pardosa pseudoannulata, an important natural predatory enemy of rice planthoppers, is found widely distributed in paddy fields. However, data on the genes involved in insecticide action, detoxification, and response are very limited for P. pseudoannulata, which inhibits the development and appropriate use of selective insecticides to control insect pests on rice. We used tr...
This work develops a methodology for estimating risk of wind-borne introduction of flying insects into a country, identifying areas and periods of high risk of vector-borne diseases incursion. This risk can be characterized by the role of suitable temperatures and wind currents in small insects' survival and movements, respectively. The model predicts the number density of introduced insects ov...
The storage hexamers are a family of insect proteins with native molecular weights around 500,000 with six homologous subunits weighing generally between 70,000 and 85,000 daltons. They are synthesized and secreted by the fat body of feeding larvae and nymphs and reach extraordinary concentrations in the hemolymph just prior to metamorphosis. In holometabolous insects, they are partially recapt...
Color patterns play central roles in the behavior of insects, and are important traits for taxonomic studies. Here we report striking and stable structural color patterns--wing interference patterns (WIPs)--in the transparent wings of small Hymenoptera and Diptera, patterns that have been largely overlooked by biologists. These extremely thin wings reflect vivid color patterns caused by thin fi...
Identifying stored-product insects is essential for granary management. Automated, computerbased classification methods are rapidly developing in many areas. A hyperspectral imaging technique could potentially be developed to identify stored-product insect species and geographical strains. This study tested and adapted the technique using four geographical strains of each of two insect species,...
Understanding variation in resource specialization is important for progress on issues that include coevolution, community assembly, ecosystem processes, and the latitudinal gradient of species richness. Herbivorous insects are useful models for studying resource specialization, and the interaction between plants and herbivorous insects is one of the most common and consequential ecological ass...
Introduction: Nutritional requirements of fungi are essential for their successful growth in laboratories. Some fungi feed on the compounds present in the insects' bodies. The aim of this study was to evaluate the effect of insects' body powder (IBP) as a supplement for the fungi growth in culture media. Methods: We used 10 mg of IBP, obtained from Anopheles superpictus and Culex theileri mosqu...
