摘　　要：利用扫描电镜对二疣犀甲[Oryctes rhinoceros(Linnaeus)]雌雄成虫的触角、下颚须和下唇须上嗅感器超微结构特征及分布进行研究。结果表明,二疣犀甲(O.rhinoceros)成虫头部存在5种感受器。触角上有3种,以板型感器为主,分布在触角鳃片表皮内陷形成的凹腔里,此外还有毛型感器、腔锥形感器。雌雄成虫触角上感器的分布模式及数量没有明显的区别;下颚须和下唇须存在4种感器,即腔锥形感器、毛型感器、末梢锥形感器、钟型感器,其中末梢锥形感器在下颚须上分布存在性二型现象,其余3种感器在雌、雄二疣犀甲下颚须和下唇须上的分布和数量无明显区别。The uhrastructure and distribution of sensilla on antenna, maxillary palp and labial palp of Oryctes rhinoceros （L） adult was observed with scanning electron microscope. The results showed that five types of sensilla on the head of adult O. rhinoceros. Five types of olfactory sensilla on its antenna were found. There were mainly sensilla placodea （S.pl） in lamellae of O. rhinoceros and these sensilla were situated in cuticle or in the sunken cavity formed by antenna1 cuticle depressions. In addition to S.pl, there were sensilla trichodea （S.tr）, sensilla coeloconica （S.co）. There were no differences in type, number and location of antenna senilla between male and female. Both maxillary palp and labial palp contained four types of sensilla, including sensilla trichodea （S.tr）, sensilla coeloconica （S.co）, sensilla twig basiconca （S.tb）, sensilla campullacea （S.ca）, and sensilla twig basiconca had difference between male and female on maxillary palp, the other three sensillas had no significant differences in type, number on maxillary palp and labial palp.
