Abstract:

Abstract: Pissodes yunnanensis is one of the serious pests of Pinus yunnanensis. Antennal sensillum of P. yunnanensis was observed with scanning electron microscopy. The results showed that the antennae of adult females and males were geniculate and made up of scape, pedicel and flagella that consised of 7 segments. Six types of sensillum were observed on the antennae of both adult females and males. They were sensillum trichodea, sensillum basiconca, feet-like sensillum, bud-like sensillum, finger-like sensillum and sensillum coeloconica. The antennae had more sensillum trichodea and finger-like sensillum than the other types of sensillum. In addition, the femal antennae had double-bud-like sensillum and the male antennae had sensillum auricillica. Finger-like sensillum, feet-like sensillum and double-bud-like sensillum were for the first time reported presented in insects of Coleoptera. The shape, distribution of these sensilla and their differences between sexes were described.
