摘要：

The sex pheromone of grape borer, Xylotrechus pyrrhoderus Bates, was isolated from body extracts and container washings of male insects, and was determined to be a mixture of (2S,3S)-octanediol (1) and (2S)-hydroxy-3-octanone (2). Each compound showed special response in electroantennogram experiments. The females were attracted by 80:20 to 95:5 mixtures of 1 and 2. This is the first time that the male sex pheromone from Cerambycidae species has been isolated and determined.
