Abstract
The antennal sensilla of the adult male and female ladybird beetle, Harmonia axyridis (Coleoptera: Coccinellidae) were examined by scanning electron microscopy. Nine types of sensilla were characterized and grouped into 5 morphological classes: , basiconic, chetiform, coeloconlc, and trichoid sensilla. sensilla were localized on the scape and pedicel, part of the ventral and dorsal proximal side. This placement suggests a role in proportion of antennal position and movement. Basiconic and chetiform sensilla were divided into 3 subtypes by morphology and length differences. Trichoid sensilla are confined to the last 2 flagellum segments on both sexes. Sexual dimorphism of antennal sensilla is limited to the three types of difference. The principal characteristics of this dimorphism are the following: a) The distribution of sensilla was differ from male and female in antennae. b) Males exhibit coeloconic sensilla not present in females; c) Females posses more trichoid sensilla than males. The possible role of specific dilference of the sensilla in intersexual communication is discussed.
