cis-9-Tetradecenyl acetate (cis-9-TDA) and cis-11-tetradecenyl acetate (cis-11-TDA), components of the sex pheromone of the smaller tea tortrix moth (Adoxophyes fasciata Walsingham), showed the potent inhibitory effect on mating of the tortricid moth under the laboratory conditions, when the compounds were presented individually or in combination. Aereal concentrations of cis-9-TDA, cis-11-TDA, and a mixture of the two (cis-9 : cis-11=7 : 3) for more than 90% inhibition of mating were 3,0.3,and 3 μg/1,respectively. trans-Isomers of 9- and 11-TDA were far less active than the cis-isomers as mating inhibitors. Distribution of the sex phermone or the individual components in the field strongly inhibited the orientation behavior of male moths to a virgin female-trap (VF-trap). However, cis-11-TDA, the best mating inhibitor under the laboratory conditions, showed only weak repressive effect on the attractive power of a VF-trap in the field, when the compound was attached to the VF-trap. cis-9-TDA was more potent than cis-11-TDA, and the trans-isomers were more active than the cis-isomers, as a represser of male attraction in VF-traps.
