Evidence for a female-produced sex pheromone in the banana pseudostem weevil, Odoiporus longicollis Olivier

Abstract

A female-produced sex pheromone in Odoiporus longicollis Olivier was detected in a laboratory bioassay system. Both virgin and mated females produce sex pheromone. There was a significant difference in response of males to females, and it varied towards females of different age groups. The calling behaviour of the females and the courtship behaviour of the males have been documented. This report is an evidence on the presence of sex pheromone in O. longicollis.
