Abstract
Eleven analogs of (E,Z)-2,13-octadecadien-1-yl acetate1, a main pheromone component of the currant clearwing moth,Synanthedon tipuliformis Clerk (Lepidoptera: Sesiidae) were synthesized and tested for their biological activities by electroantennography (EAG). To correct the EAG data for differences in volatility of the analogs, their vapor pressures were estimated by a gas chromatographic method. All structural changes in the parent molecule were found to reduce the biological activity to various degrees. The most active analog tested was the carbamate12, whose activity was almost comparable to that of the pheromone component1. Structure-activity correlations showed that hydrophobic, steric, and electronic effects of chain terminal groups might be responsible for variations in biological activity of the conformationally unchanged (E,Z)-2,13-analogs
