Technical Abstract: Slowly but surely antennal electrophysiology, in particular coupled gas chromatography electroantennographic detection (GC-EAD), has moved from a specialty to just another tool in the toolbox of the chemical ecologists. Originally developed for lepidopteran antennal responses, this technique is used more and more for the detection of non-lepidopteran semiochemicals. The equipment and setup for lepidopteran GC-EAD is relatively standardized; however, the diversity in antennal morphology of non-lepidopteran antennae dictates some minor but often unreported adaptations to the method of GC-EAD analysis. Examples of such adaptations are discussed with newly identified coleopteran pheromones.
