Basic and Applied Chemical Ecology in Cerambycid Beetles

Exploring the nature of Arhopalus ferus (Coleoptera: Cerambycidae: Spondylidinae) pheromone attraction

Cerambycid species of the Spondylidinae subfamily are distributed worldwide and are known for being prolific invaders that infest conifers. They are no strangers to NZ where Arhopalus ferus, the Burnt pine longhorn beetle, is well-established and requires monitoring at high-risk sites such as ports, airports, and sawmills. This monitoring is required as part of the requirements to meet pine log export standards set by the Ministry of Primary Industries (MPI), and its surveillance is highly reliant on trapping using a lure composed only of host volatiles. Over the past 15 years, research on cerambycid pheromones has expanded worldwide through the identification of more than 400 cerambycid pheromone attractants. Recent advances in the area of cerambycid pheromones have allowed for pheromones to be synthesized for use as lures in traps. More recently, the identification of the male-produced aggregation pheromone in Arhopalus rusticus has enabled investigations into the nature of A. ferus pheromone attraction. Here we present our research, using laboratory and field bioassays to identify the specific chemical components responsible for A. ferus attraction, which may be used to help develop pheromone-based monitoring tools in New Zealand.
