Abstract

Electroantennography is a useful method for detecting biological activity in a wide variety of compounds. This study has demonstrated a good correlation between electrophysiological and behavioural bioassays of termite repellency. All quinones and monoterpenes which were repellent to Reticulitermes lucifugus santonensis gave a good electroantennogram response (EAG). The quinones and monoterpenes which did not give an EAG response were non-repellent. Three-dimensional molecular shape clearly plays an important part in the chemoreception process. Molecular vibration frequencies in the far i.r. region could not be correlated with olfactory specificity of termite repellents.
