Abstract

The antennal morphology of Psylliodes chrysocephala L. (Coleoptera: Chrysomelidae), an important pest of oilseed rape (Brassica napus), was studied. Two types of tricellular, integumentary glands were found. The common antennal glands are distributed under all sensilla-bearing parts of male and female antennae. The male-specific antennal glands are only located under a glabrous area found on antennomeres 6-10 of male beetles. The common antennal glands are synthetically active in both pre- and post-diapause adults, but the male specific antennal glands are only active in post-diapause (reproductively active) males. During studies of mating behaviour, the antennae of the males were highly active at the beginning and end of copulation, and in response to increased female activity. The male specific antennal glands may secrete a sex pheromone, and the glabrous area on the male antennae could be the release site for such a pheromone.
