摘    要:应用扫描电镜(SEM)对椰心叶甲啮小蜂Tetrastichus brontispae Ferrière成虫触角感器的超微结构进行观察。结果表明,在触角上共有8种感器,分别为毛形感器、多孔板状感器、刺形感器、锥形感器、耳形感器、乳状感器、腔形感器和Bhm氏鬃毛;其中毛形感器和板形感器是主要感器,数量较多分布较广;雌雄蜂触角有明显的性二型现象,表现为雌雄触角大小不同,触角感器类型、大小、数量、分布不同。

关 键 词:椰心叶甲啮小蜂  触角  感器  扫描电镜

Abstract:The morphology of sensilla on the antennae of Tetrastichus brontispae Ferrière adult were observed under a scanning electron microscope.Eight distinct types of sensory receptors were found,including sensilla trichodea,sensilla multiporous plate,sensilla chaetica,sensilla basiconica,sensilla auricillica,sensilla mammilliformia,sensilla coeloconica and bhm bristles,of which sensillum trichodeum and sensillum placodeum were both the most numerous and widely distributed.Sexual dimorphism in antenna size and the shape,size,number and distribution of sensilla,was apparent.
Keywords:Tetrastichus brontispae  antenna  sensilla  scan electron microscope
