【摘要】 利用扫描电镜对荒川库蠓 (Culicoidesarakawae)和尖喙库蠓 (C .schultzei)的触角及其感觉器、肩窝和触须感觉器进行了研究 在触角上共发现七类感觉器 ,即腔锥感器、钟形感器、球状感器、锥形感器、毛簇感器、毛状感器和触角毛 比较研究发现 ,两种库蠓之间触角感觉器的种类、数量、排列及分布均有差异 ,其中腔锥感器具有种间鉴别意义 ;肩窝不具有种内的稳定性 ;触须感觉器不具有种间差异更多还原

【Abstract】 There were seven types of antennal sense organs including sensilla coeloconica, sensilla campanulate, sensilla orbiculate, sensilla basiconica, sensilla trichodea, sensilla trichodea and antennal hair in culicoides by scanning electron microscope observation. The patterns of the sense organs on the antennae were described and compared. It was found that the type, number and patterns of the sense organs were different between C. arakawae and C. schultzei , and sensilla coeloconica could be used to discriminate the two species of biting midges. The humeral pits of the same species of midges varied, but the two species of midges had same patterns of maxpalpal sensilla.更多还原
