Abstract
( Z,E )-9,l2-tetradecadien-1-ol acetate ( Z,E -9,12-TDDA), ( Z )-9-tetradecen-1-ol acetate ( Z -9-TDA), and ( Z )-9-dodecen-1-ol acetate ( Z -9-DDA) significantly reduced captures of ♂ Trichoplusia ni (Hubner) when these compounds were evaporated separately in the same trap with T. ni sex pheromone, ( Z )-7-dodecen-1-ol acetate. However, when the same compounds were present throughout a small area (81 m2) as a background odor, catches of T. ni males in pheromone traps were not affected. The situation was different with Spodoptera exigua (Hubner). Catches in traps were reduced significantly when Z -9-DDA and Z -9-TDA were evaporated from female-baited pheromone traps and when they were evaporated into the atmosphere surrounding traps. Z,E -9,12-TDDA was also effective in disrupting orientation of S. exigua males to females when it was evaporated into the atmosphere. The reasons for the differences in results obtained with T. ni in the 2 (trapping and atmospheric permeation) tests are obscure.
