Observations on the Mating Behavior and Bioassay for the Sex Pheromone of the Yellow Peach Moth, Dichocrocis punctiferalis GUENEE (Lepidoptera : Pyralidae)

Abstract

Calling and mating behaviors of the fruit-feeder type yellow peach moth, Dichocrocis punctiferalis GUENEE were observed. Two simple types of bioassay in laboratory were developed to isolate and identify the sex pheromone. The preliminary isolation of the sex pheromone was also made with CH₂Cl₂ extraction of the female abdominal tips and and by Florisil column chromatography.
