摘　　要：作为探讨栗山天牛成虫的寄主选择、配偶定位等行为机制的一部分,利用扫描电镜对栗山天牛触角的形态、感受器的类型及分布特点等进行观察。结果表明:栗山天牛触角上有锥形感受器7个亚型、刺形感受器4个亚型、毛形感受器2个亚型、齿形感受器2个亚型、芽形感受器1个亚型、钟形感受器1个亚型;锥形感受器Ⅳ、刺形感受器Ⅳ为雌虫特有的感受器,锥形感受器Ⅴ、锥形感受器Ⅵ、锥形感受器Ⅶ、毛形感受器Ⅰ和钟形感受器为雄虫特有的感受器;触角感受器数量上雌虫多于雄虫,雌虫触角腹面感受器数量略多于背面,但都差异不显著。栗山天牛雌雄成虫触角上感受器的数量、类型和分布等的差异表明,雌雄虫可能对环境中的物理、化学信息的反应存在一定差异。As part of studies to understand the mechanisms of host and mate selection by adult Massicus raddei Blessig （Coleoptera： Cerambycidae）, we used scanning electron microscopy （SEM） to observe and describe the morphology of antennal sensilla on adults of both sexes. We observed seventeen different types of sensilla, seven types of sensilla basiconica, four types of sensilla chaetica, two types of sensilla trichodea, two types of sensilla dentiform, one type of sensilla gemmiformium, and one type of sensilla campaniformia. Differences were observed between males and females： Basiconica Ⅳ and chaetica Ⅳ were peculiar to females whereas basiconica Ⅴ, basiconica Ⅵ, basiconica Ⅶ, trichodea Ⅰ and campaniformia were found only in males. Antennae of females had more sensilla than those of males, and also had slightly more sensilla on the renter than on the dorsum, differences were insignificant. Differences between sexes in the number, type, and distribution of antennal sensilla on adult M. raddei suggest that males and females may differ in response to certain chemical and physical stimuli in the environment.
