摘要：

明确榛实象(Curculio dieckamanni)雌雄成虫头部、喙及口器感器类型、数量、分布及形态特征。利用扫描电镜观察榛实象雌雄成虫头部、喙及口器感器类型、数量、分布及形态特征。在榛实象雌雄成虫头部发现有3种类型的感器，分别为鳞形感器、臼窝状感器和表皮孔，雌雄虫头部感器类型不存在雌雄异型现象；其中鳞形感器数量雌虫中显著高于雄虫(P<0.05)，臼窝状感器数量在雌雄虫间差异不显著(P>0.05)，表皮孔在雌雄虫头部均仅分布有1个。在榛实象雌雄成虫的喙，发现1种感器为腔锥形感器，该感器数量在雌虫中显著高于雄虫(P<0.05)。在榛实象雌雄成虫口器上发现有4种类型的感器，分别为锥形感器、柱形感器、鱼鳍形感器和轴承短锥形感器，榛实象成虫口器感器种类在雌雄间无异型现象，锥形感器、柱形感器、鱼鳍形感器和轴承短锥形感器分布数量在雌雄间相同。该项研究对榛实象成虫头部、喙及口器感器类型、数量、分布及形态特征进行了观察和分析，这些结果为进一步开展榛实象的行为生态学及生理学的研究提供基础依据。

Abstract:

The purpose of this study is to clarify the type, quantity, distribution and morphological characteristics of head, proboscis and mouthparts sensilla of the female and male adults of C. dieckamanni. Scanning electron microscope was used for the observation. Three types of sensilla were found in the heads of both male and female adults, namely sensilla squamiformia, dimples sensilla and cuticular pore. There was no dimorphism in the types of head sensilla in males and females. The number of sensilla squamiformia was significantly higher in females than that in males (P<0.05). The number of dimples sensilla was not significantly different between males and females (P>0.05), and there was only one cuticular pore in the head of both males and females. We found only one type of sensilla in the proboscis of male and female adults - the sensilla coeloconica, the number of which was significantly higher in females than that in males (P<0.05). Four types of sensilla were found in the mouthparts of both male and female adults of C. dieckamanni, namely sensilla basiconica, sensilla cylindric, fin sensilla and bearing short basiconic sensilla. There was no dimorphism between males and females in the types of mouthparts sensilla of C. dieckamanni, and their numbers were the same. In this study, we observed and analyzed the type, quantity, distribution and morphological characteristics of the head, proboscis and mouthparts sensilla of adult C. dieckamanni, and these results can provide a basis for further research on the behavioral ecology and physiology of C. dieckamanni.
