摘　　要：应用扫描电镜和透射电镜对落叶松重要枝梢害虫松瘿小卷蛾触角感器类型、结构、分布进行研究。松瘿小卷蛾触角共有8种感器:毛形感器、锥形感器、耳形感器、栓锥形感器、刺形感器、腔锥形感器、板形感器和Bhm氏鬃毛。雌雄触角感器分布特点相同,但类型、数量不同,有性二型现象。在鳞翅目昆虫触角上观察到板形感器,其顶端具孔,可能具有味觉功能。Larch bark moth, Cydia zebeana（Lepidoptera：Tortricidae） is an important shoot pest of larch. This paper reported the antennal uhrastructure of sensillum and distribution observed by both scanning and transmission electron microscopes. Eight types of sensillum were found ： sensillum trichodea, basiconica, auricillica, styloconica, coeloconica, chaetica, placodea and Bohm breistles. Though the sensillum distribution characteristic of different genders was the same, the sensillum types and numbers in male and female showed dimorphism. It is worth to note the sensillum placodea with a tip pore was for the first time reported in lepidopterous moths, which might possess taste sense function.
