【摘要】 印度谷螟Plodia interpunctella(H ǜbner)是世界性的贮粮害虫。本文对其触角用扫描电镜进行了研究。其触角为丝状,由基部的柄节、梗节和43～45节鞭节组成。共发现了毛形感受器、刺形感受器、腔锥感受器、栓锥感受器、锥形感受器、耳形感受器和鳞形感受器等共七种感受器,并研究了它们在触角上的分布和数量。感受器在雌、雄蛾上也有很大差异,特别是毛形感受器、耳形感受器和刺形感受器。另外发现了又一种类型的锥形感受器,此种形状的感受器在国内外都未见报道。更多还原

【Abstract】 Indian meal moth, Plodia interpunctella(Hübner) (Lepidoptera: Pyralidae) is a worldwide pest of stored grain. In this paper, the antenna of Indian meal moth are studied with scanning electron microscopy. The antenna of Indian meal moth is filiform and consists of two basal segments, scape and pedical, and 43-45 terminal segments of the flagellum. Seven types of sensilla are presented: sensilla trichodea, sensilla chactica, sensilla coeloconica, sensilla styloconica, sensilla basiconica, sensilla auricillica and sensilla squamiformia. And the numbers and distributions of various sensilla on the antenna are observed. Sexual dimorphism of this species is marked on the tpyes of sensilla, especially in the number, length and location of sensilla trichodea, sensilla auricillica and sensilla chaetica. Counts and measurements of the various sensilla are made on the selected segments for 4 males and 4 females respectivley. In addition, another new type of sensilla are founded, which haven’t reported up to date.更多还原
