利用环境扫描电镜观察光肩星天牛雌雄成虫触角感受器的超微结构、类型和分布。结果表明:光肩星天牛触角为线形,共11节,即柄节、梗节和9个鞭节。在雌雄成虫的触角上均存在5类13种感受器,包括5种刺形感受器、2种毛形感受器、4种锥形感受器、1种钟形感受器和1种指形感受器。雌雄个体之间触角感受器的类型没有明显差异,但感受器的分布存在性二型现象。
Ultra-structure,number and distribution of sensilla on the antennae of Anoplophora glabripennis were observed and studied with an environmental scanning electron microscope.The results show that the linear antenna consists of the scape,pedicel and nine flagellomeres.There are 5 types and 13 kinds of sensilla on the antennae,including 5 kinds of sensilla chaeticas,2 kinds of sensilla trichodeas,4 kinds of sensilla basiconcas,1 kind of sensilla campullacea,and 1 kind of finger sensilla.No difference is found in the type of sensilla between male and female adults.However the sensilla distribution in male and female shows dimorphism.
