Abstract: | "We tested differences in female pheromone production and male response in three species of the genus Adoxophyes in Korea. Females of all three species produced mixtures of (Z)-9-tetradecenyl acetate (Z9-14:OAc) and (Z)-11-tetradecenyl acetate (Z11-14:OAc) as major components but in quite different ratios. The ratio of Z9-14:OAc and Z11-14:OAc in pheromone gland extracts was estimated to be ca. 100:200 for Adoxophyes honmai, 100:25 for Adoxophyes orana, and 100:4,000 for Adoxophyes sp. Field tests showed that males of each species were preferentially attracted to the two-component blends of Z9-14:OAc and Z11-14:OAc mimicking the blends found in pheromone gland extracts of conspecific females. The effects of minor components identified in gland extracts on trap catches varied with species. Addition of 10-methyldodecyl acetate (10me-12:OAc) or (E)-11-tetradecenyl acetate (E11-14:OAc) to the binary blend of Z9-14:OAc and Z11-14:OAc significantly increased captures of A. honmai males, whereas E11-14:OAc exhibited a strongly antagonistic effect on catches of Adoxophyes sp. males. Moreover, (Z)-9-tetradecen-1-ol (Z9-14:OH) or (Z)-11-tetradecen-1-ol (Z11-14:OH) added to the binary blends increased attraction of male A. orana but not A. honmai and Adoxophyes sp. males, suggesting that these minor components, in addition to the relative ratios of the two major components, play an important role in reproductive isolation between Adoxophyes species in the southern and midwestern Korea where these species occur sympatrically" |
