摘  要：
用扫描电镜观察玉米螟赤眼蜂 (Trichogrammaostriniae)、拟澳洲赤眼蜂 (T .confusum)及松毛虫赤眼蜂 (T .den drolimi)雌蜂触角上感器的外部形态 ,比较其感器的数目和着生位置。发现了镰刀形感器背面的特殊形态 ,并确定了其功能。确定了位于触角端部的单孔毛形感器为味觉器。 3种赤眼蜂棒节腹面的镰刀形感器数目及棒节背面板形感器的形态和嗅孔密度存在差异 ;玉米螟赤眼蜂的坛形感器与其他 2个种在形态上也具有较大差异。

摘  要：
The external morphology of antennal sensillum were observed by scanning electron microscopy(SEM)for female species of Trichogramma ostriniae,T.confusum and T.dendrolimi(Hymenoptera:Trichogrammatidae).The numbers and the relative positions of these sensillum were depicted.The special structure on the ventro-lateral margin of falcate sensilla was discovered and its function was confirmed.The sensillum uniporous trichodenum on the apex of the antenna was proved to perform gustatory function.The differences in the numbers of falcate sensillum,the densities of olfactory pores and shapes of placoid sensillum and the shapes of ampullaceum sensillum among the three species of Trichogramma,were also discussed.
