Reproductive Isolation of Two Tortricid Moth Species by Different Ratios of a Two-Component Sex Attractant

Abstract

Two tortricid mitoth species, Adoxophyes orana and Clepsis spectrana, utilize the samne two isomers, cis-9- and cis-l1-tetradecenyl acetate, as their sex attractant. Commnlunication between the sexes of each species is separated effectively by a different blendinig of both compounds by the females and a different response to these blends by the males.
