- A dual‐choice olfactometer is described in which laboratory bioassays were conducted to test the response of adults of banded fruit weevil, Phlyctinus callosus, to frass from adults of both sexes. Mixed‐sex frass, male frass and female frass were highly significantly attractive to the adults. Both sexes were attracted, although significantly more males than females were attracted to male frass. Evidence strongly suggests that the attractive component in the frass is an aggregation pheromone. This is the first record of chemical communication in this species. These results have prompted an investigation into the chemical analysis of P. callosus frass.
