中文摘要:
      为了解豆卜馍夜蛾Bomolocha tristalis Lederer成虫触角感器的类型、超微结构、数量和分布, 探索其化学感受机制。利用扫描电镜技术对豆卜馍夜蛾雌、雄蛾的触角感器进行观察。结果表明: 在豆卜馍夜蛾触角上共观察到8种类型感器: B?hm氏鬃毛(两种亚型, BBⅠ型和BBⅡ型)、毛形感器、锥形感器、刺形感器、腔锥形感器、耳形感器、鳞形感器和栓锥形感器。其中毛形感器数量最多, 其次是腔锥形, 除刺形和栓锥形感器外, 其他感器数量在触角鞭节从基部到端部呈现由少到多, 再减少的趋势。毛形、锥形和耳形感器表皮具多孔属于嗅觉感器。雄蛾触角与雌蛾相比, 鞭亚节多2~4节; 毛形、刺形和鳞形感器明显长于雌蛾, 耳形感器明显短于雌蛾; 毛形和腔锥形感器数量均明显多于雌蛾。豆卜馍夜蛾触角感器种类丰富, 数量较多, 雌、雄蛾间存在性二型现象, B?hm氏鬃毛、刺形和栓锥形感器在结构和分布上存在有利其功能的特化现象。
英文摘要:
      The aim of this study was to clarify the types, ultrastructure, quantity and distribution of sensilla on the antennae of Bomolocha tristalis adult and explore the chemosensory mechanism. The sensilla on female and male adult antennae of B. tristalis were observed by scanning electron microscope. The results showed that eight types of sensilla including B?hm bristles (two subtypes, BBⅠ and BBⅡ), trichodea, basiconica, chaetica, coeloconica, auricillica, squamiformia, styloconica were detected on the antennae of B. tristalis. The amount of sensilla trichodea was most among these sensilla, followed by coeloconica. Except for sensilla chaetica and styloconica, the amounts of other sensilla on the flagellum from the base to the end showed a trend from less to more and then less. Sensilla trichodea, basiconica and auricillica were multiporous on the cuticle, which were considered to be olfactory organ. The flagellum of male antennae had 2-4 segments more than that of female moth. Sensilla trichodea and chaetica of male moth were significantly longer than that of the female moth. Sensilla auricillica of male moth were significantly shorter than that of the female moth. The amounts of sensilla trichodea, chaetica, coeloconica, auricillica and styloconica of male moth were more than those of female. It was evident that the antennal sensilla of B. tristalis were abundant, and the antennae exhibited obvious sexual dimorphism. Moreover, the specialization phenomenon that is beneficial for the sensilla function occurred in the structure and distribution of B?hm bristles, sensilla chaetica and styloconica.
