Abstract
field attraction test of (7R,8S)-cis-7,8-epoxy-2-methyloctadec-17-ene (= 7R,8S-epo-2me-17ene-18Hy), a trace component of the sex pheromone gland of the Asian gypsy moth, (Lymantria dispar), traps that were baited with the trace component attracted more L. dispar than traps baited with (7S,8R)-cis-7,8-epoxy-2-methyloctadec-17-ene (= 7S,8R-epo-2me-17ene-18Hy) and unbaited traps. However, traps baited with 7R,8S-epo-2me-17ene-18Hy were less attractive than traps baited with (+)-disparlure [= (7R,8S)-cis-7,8-epoxy-2-methyloctadecane], the sex pheromone of L. dispar. Combination tests with (+)-disparlure, 7R,8S-epo-2me-17ene-18Hy, and 7S,8R-epo-2me-17ene-18Hy revealed that 7R,8S-epo-2me-17ene-18Hy acted synergistically with (+)-disparlure.
