中文摘要:
      咖啡灭字虎天牛 Xylotrechus quadripes Chevrolat是咖啡树的重要害虫, 其以幼虫钻蛀为害木质部的特点造成防治十分困难。本文利用扫描电镜对新羽化的咖啡灭字虎天牛雌、雄成虫触角、前足感器类型及分布进行了观察, 结果表明:该虫触角呈线状, 共11节, 可分为3部分:柄节、梗节和鞭节(9亚节)。雌、雄成虫触角感器共有5类, 分别为刺形感器、锥形感器、凹槽钉形感器、栓锥形感器、B?hm氏鬃毛, 其中刺形和锥形感器各有3个亚型, 不同类型的感器在触角各节上的数量和分布均有差异。雌、雄成虫触角感器存在性二型现象, 栓锥形感器为雄虫所特有。前足为步行足, 感器共有3类, 分别为刺形感器、锥形感器和毛形感器, 其中刺形感器有5个亚型, 雌、雄成虫足感器无性二型现象。
英文摘要:
      Xylotrechus quadripes Chevrolat is the foremost pest of arabica coffee. Damage inflicted to coffee stems by wood-boring larvae causes difficulty in chemical control. In this study, the sensilla on the antenna and propodium of male and female adults of X. quadripes were observed under scanning electron microscope.The results showed that the linear antenna consisted of scape, pedicel and flagellum (composed of nine subsegments). Five types of sensilla were found on the antenna, including sensilla chaetica (subtype Ⅰ, Ⅱ, Ⅲ), sensilla basiconca (subtype Ⅰ, Ⅱ, Ⅲ), sensilla grooved peg, sensilla styloconica and B?hm bristles. The quantity and distribution of each kind of sensillum differed among segments of the antenna. However, sexual dimorphism in sensillum was apparent: sensilla styloconica was only observed on male antenna. The propodium belongs to walking leg, on which three types of sensilla were found, including sensilla chaetica (subtype Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ), sensilla basiconica and sensilla trichodea. The types and morphology of sensilla on the propodium were similar between male and female adults.
