摘　　要：本文利用光学显微镜和和扫描电子显微镜,观察和测定椰子织蛾成虫的触角外部形态、感器的形态特征和分布,对椰子织蛾感器进行鉴定分类。结果表明,椰子织蛾雌雄成虫触角形状为线形,由38~42节组成,其中柄节1节、梗节1节和鞭节36~40节。椰子织蛾雌、雄成虫触角上有7种类型感器,9种亚型,分别是毛形感器(2种亚型)、刺形感器(2种亚型)、锥形感器(3种亚型)、鳞形感器、腔锥形感器(2种亚型)、栓锥形感器和Bohm氏鬃毛。通过观测得出,椰子织蛾雌、雄虫感器存在性二型现象。本研究为揭示椰子织蛾成虫化学通讯机制提供形态学基础。Optical microscope and scanning electron microscope were used to observe and determine the morphology and distribution of antennae of adult Opisina arenosella,and to identify and classify the sensory organs of O.arenosella.The results showed that the antennae of male/female adults were linear shape and composed of 38~42 knots,including 1 scape,1 pedicel and 36~40 flagellum.There were 7 sensilla types and 9 subtypes on the antennae of the female and male adults,including sensilla trichodea(2 subtypes),sensilla chaetica(2 subtypes),sensilla basiconica(3 subtypes),sensilla squacmiformia,sensilla coeloclnica(2 subtypes),sensilla styloconica and Bohm bristles.There was a dimorphism in male and female adults.This study provided morphological basis for revealing the chemical communication mechanism of O.arenosella.
