摘  要:
烟盲蝽Nesidiocoris tenuis(Reuter)作为一种杂食性昆虫,是蔬菜害虫的重要捕食者。利用扫描电镜对烟盲蝽雌雄成虫的触角进行观察,结果表明:烟盲蝽触角由基节、柄节、梗节和鞭节组成。绝大部分触角感器位于触角的腹面和外侧面。触角感器共有9种,分别为毛形感器、刺形感器、锥形感器、钟形感器、腔锥形感器、具弯钩形感器、腔形感器、乳形感器和Bhm氏鬃毛。腔锥形感器仅见于雌性触角,其他8种感器在雌雄两性触角上的类型和分布没有明显的区别。

摘  要:
The tobacco plant bug,Nesidiocoris tenuis(Reuter)(Heteroptera:Miridae),is an effective predator of the pests of vegetable crops.The morphological structure of the antennae in adult N.tenuis was observed with a scanning electron microscope.The antennae of males and females consisted of a base segment,scape,pedicel and flagellum.Nine types of sensilla were found on the antennae of both sexes;sensilla trichodea,sensilla chaetica,sensilla basiconca,sensilla campaniformia,sensilla coeloconica,bent-tipped sensilla,sensilla cavity,sensilla mammilliformia and Bhm bristles.Most sensilla are located on the underside and outside lateral surfaces of the antennae.Sensilla coeloconica was only seen on the antennae of females;no other obvious sexual dimorphism in the type and distribution of sensilla was apparent.
