Abstract
Analysis of sex pheromone glands from individual female soybean looper moths showed that in addition to the previously identified main component (Z)-7-dodecenyl acetate, the compounds dodecyl acetate, 11-dodecenyl acetate, (Z)-7-dodecenyl propionate, and (Z)-7-dodecenyl butanoate were also produced. Two of the components, 12∶OAc and 11–12∶OAc, were not detected in a single analysis of female effluvium. Flight-tunnel tests showed that the five-component and three-component blends were equal to each other and to a female extract (> 80% source contacts) and that the mixtures were superior toZ7–12∶OAc alone. Field tests indicated that the five-component blend was significantly more attractive thanZ7–12∶OAc alone at a dosage of 1 mg, but that the blend was only slightly better at 3 mg.
