| Research Abstract |
Adult Anoplophora malasiaca were collected from field populations inhabiting three different host plants: Citrus, Salix and Vaccinium. Males of three populations were attracted most frequently to odors of their original hosts, indicating that male orientation behavior was induced by the odors of the plants from which they were originally collected. We also observed the mating responses of the males to elytra extracts from young and mature females of the three populations and chemically analysed those extracts. All eight hydrocarbons, four ketones, and three lactones that were previously identified as female contact sex pheromones were found in the extracts of three populations and both ages. Higher amounts of lactones on mature females likely caused greater male responses.
These results suggested that males would be more likely to approach a female feeding on the same host plant and subsequently recognize her sexual maturity based on the profile of contact sex pheromones on her elytra.
