Eleven synthetic drimane compounds were tested for their deterrency to nymphs of Myzus persicae (Sulzer) and Aphis gossypii (Glover) (Homoptera: Aphididae). In general, A. gossypii nymphs were less sensitive to the drimanes than M. persicae nymphs. Warburganal (1) and polygodial (2), with a beta-dialdehyde configuration and double bond at C7-C8, were highly active as deterrents and/or feeding inhibitors against both species. One of the synthetic compounds (10) showed relatively high activity against A. gossypii, while it was not active at all against M. persicae, indicating that synthetic analogs of natural deterrents can be highly selective feeding deterrents. From 24-hr interval observations and ablation studies, it is concluded that nymphs of both M. persicae and A. gossypii detect polygodial and possibly the other drimanes tested With contact chemosensilla at the tips of their antennae. The ablation studies also showed that in both species no tarsal, labial, or epipharyngeal sensilla are involved in detecting polygodial within 24 hr
