半闭弯尾姬蜂触角感觉器的超微结构研究

Ultrastructural studies on the antennal sensilla of Diadegma semiclausum Hellen (Hym., Ichneumonidae)

采用扫描电镜观察了半闭弯尾姬蜂触角表面的超微形态.结果表明,在雌、雄蜂的触角上共存在着7种感觉器,分别为毛形感觉器、刺形感觉器、板形感觉器、B hm氏鬃毛、柱形感觉器、锥形感觉器、钟形感觉器.对触角感觉器的形态、分布进行了描述,并对两性间的差异进行了讨论.

Antennal surface structure of Diadegma semiclausum Hellen was observed by scanning electron microscope. Seven types of sensilla were found on the antennae of both the female and the male. They were sensillum trichodeum, sensillum chaetium, sensillum placodea, Bhm bristles, sensillum cylindric, sensillum basiconca, and sensillum campaniformia, respectively. The shape of these sensilla and their distribution were described, and their difference between sexes was discussed.
