The diamondback moth, Plutella xylostella, (Lepidoptera: Plutellidae) is a major pest of the cruciferous vegetables in many parts of the world. The virgin female moth produces three sex pheromones, (Z)-11-hexadecenal (Z11-16:Al), (Z)-11-hexadecenyl acetate (Z11-16:Ac) and (Z)-11-hexadecenol (Z11-16:OH) to attract male adults. We used GC-MS to analyze different compounds in diamondback moth lures and found that the components and ratios of the compounds differ among the diamondback moth lures, and the differences are confirmed and well correlated with the male moth captures under field conditions.
