Identification of the Male-Produced Aggregation Pheromone of the Four-Spotted Coconut Weevil, Diocalandra frumenti.

The four-spotted coconut weevil, Diocalandra frumenti Fabricius (Coleoptera: Dryophthoridae), is a small weevil found attacking economically important palm species, such as coconut, date, oil, and Canary palms. Given the scarcity of detection and management tools for this pest, the availability of a pheromone to be included in trapping protocols would be a crucial advantage. Previous laboratory experiments showed evidence for aggregation behavior; thus, our main goal was to identify the aggregation pheromone in this species.
