title: Sex pheromone of the tomato looper,Plusia chalcites (ESP).
abstract: Z-7-Dodecenyl acetate (A) andZ-9-tetradecenyl acetate (B), in a 5∶1 ratio, have been identified as sex pheromone components of femalePlusia chalcites. In addition, small amounts of dodecyl acetate, tetradecyl acetate, hexadecyl acetate, andZ-9-dodecenyl acetate have been found in the abdominal tip extracts. This is the first known Plusiinae species which utilizes a two-component primary sex pheromone system. The most effective lure found in field experiments was a mixture of 1 mg A and 0.2 mg B absorbed on rubber septa.
