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

Abstract
Two tortricid moth species, Adoxophyes orana and Clepsis spectrana , utilize the same two isomers, cis -9- and cis -11-tetradecenyl acetate, as their sex attractant. Communication between the sexes of each species is separated effectively by a different blending of both compounds by the females and a different response to these blends by the males.
