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.
