Abstract:Massicus raddei (Blessig) is a major wood boring pest of chestnut trees in Northeastern China that has caused serious damage to the local economy and ecology. It also attacks the trunk of Quercus mongolica and Quercus liaotungensis. Antennae are the main sensory organ of this longhorned beetle and the types and distribution of antennal sensilla on the antenna can influence adult’s recognition of chemical signals. By means of scanning electron microscopy, antennal sensilla on the antenna of male and female M. raddei were inspected and compared. Results show that though the distribution of antennal sensilla was slightly different between the sexes, there were many sensillum trichoid, sensilla bascionica, sensilla auricillica, and a small quantity of sensillum finger, sensilla placodeum, and sensilla campaniform, etc, on the antennae of both sexes. There are more antennal sensillae on the terminal segments of the antennal flagellum than on the basal segments. The distribution of antennal sensillae on the antennal flagellum might relate to different functions performed by different segments of the antenna.
