摘　　要：利用扫描电镜对杨小舟蛾(Micromelalopha troglodyta(Graeser))成虫触角感觉器的形态、分布进行了观察。结果表明:杨小舟蛾触角上存在11种感觉器,分别为毛形感器、刺形感器、腔锥形感器、腔形感器、柱形感器、栓锥感器、耳形感器、叉形感器、芽形感器、Bǒhm氏鬃毛和鳞形感器。其中,毛形感器有4种类型,栓锥感器、Bǒhm氏鬃毛各有3种类型,腔锥形感器、叉形感器、鳞形感器各有2种类型,其余各有1种类型。绝大部分触角感觉器位于触角的腹面和侧面。雌、雄蛾触角上的感器种类大体相同,但也存在差异。雌蛾触角上没有叉形感器及腔锥形感器的第2种类型,雄蛾触角上没有发现芽形感器以及Bǒhm氏鬃毛的第1种和第2种类型。另外,毛形感器的长度、数量在两性之间也存在差异。The morphology and distribution of antennal sensilla were studied using scanning electron microscopy in Micromelalopha troglodyta（Graeser）.The results showed that eleven distinct kinds of antennal sensilla,including sensilla trichodea,sensilla chaetica,sensilla coeloconica,sensilla cavity,sensilla cylindric,sensilla styloconica,sensilla auricillica,sensilla furcatea,sensilla gemmiformia,Bǒhm bristle and sensilla squamiformia,were observed.Furthermore,four types of sensilla trichodea,three types of sensilla styloconica or Bǒhm bristle,two types of sensilla coeloconica,sensilla furcatea or sensilla squamiformia,and one type of the others were researched,and most of them lie on the upper and lower surfaces of the antenna.In addition,antennal sensilla were quite similar except some slight differences between the female and male individual adult.Sensilla furcatea and the second type of sensilla coeloconica weren＇t found in the female adult antenna,while sensilla gemmiformia the first and the second type of Bǒhm bristle（BB2） weren＇t found in the male adult antenna.Moreover,there were differences in the length and quantity of sensilla trichodea between the sexes.
