The mating behaviour of the banana weevil, Cosmopolites sordidus Germar (Coleoptera : Curculionidae)

May 2015

The banana weevil, Cosmopolites sordidus Germar mates repeatedly in its lifetime. No elaborate courtship behavior was seen before mating in the laboratory. However, ‘sniffing’ (an activity by which male weevils used their antennae to contact the abdominal tip of the female, as if to perceive some stimulus), often preceded mating. This observation may be an indication of a chemical pheromone involved in the...
