Researchers studying hydrocarbons in insect cuticles typically avoid specimens preserved in ethanol, for fear the solvent may interfere with chemical analysis. A new study, however, finds ethanol has little effect—at least in the case of one wasp species tested—and opens the possibility that ethanol-preserved insects can indeed be used for the analysis of cuticular chemical compounds.
Biosecurity research at Kansas State University adds to the chorus of studies showing mosquitoes and other insects are not biological vectors of SARS-CoV-2, the coronavirus that causes COVID-19. Here's a look at how that research is conducted.
In Uganda and neighboring African nations, wild grasshoppers are a delicacy and are commonly harvested for their use as food. A team of researchers has designed a new trap that improves on the traditional model by reducing nontarget bycatch, energy consumption, and use of hazardous materials.
The Asian longhorned beetle, a federally regulated invasive woodboring pest, was recently discovered in South Carolina—hundreds of miles from the nearest known infestation. Federal and state officials are working hard to try to eradicate this pest, and there are many research questions and opportunities associated with this infestation.
When dung beetles show up at an animal carcass, they're more attracted to the head end than the rear, new research shows, suggesting it may not just be exposed gastrointestinal contents they're after.
