Abstract
Determination of electroantennograms (EAGs) with an electroantennometer having a positive and a negative peak detection option, and with a stimulus delivery device providing local stimulation of the antenna ofP. americana, allowed for the detection of three typical EAG patterns for a wide range of compounds tested. Some of the compounds presented at least one positive EAG peak (0.1–0.3 mV), others showed a single negative EAG peak (−1.0 to −1.1 mV), and a third group had more than one negative EAG peak (−0.2 to −0.8 mV). These EAG results correlate with behavioral assays ofP. americana. Thus compounds having a positive EAG response act as repellents, while those having negative EAG responses act as attractants, depending on concentration. EAG patterns thus can permit prediction of behavioral responses ofP. americana.
