Can Cuticle Compounds Be Extracted From Insects Preserved in Ethanol?

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.

Study on Mosquito Landing Rates Could Improve Repellent Testing

Research on the rate at which mosquitoes land on people in field tests and lab tests finds that common arm-in-cage test results differ significantly from those found in large-room or field tests. The findings point the way toward making tests of mosquito repellents more aligned with real-world conditions.
