大豆食心虫触角感器的扫描电镜观察

Observation on antennal sensillia of Leguminivora glycinivorellawith scanning electron microscope

利用扫描电镜观察了大豆食心虫Leguminivora glycinivorella Matsumura成虫的触角感器的形态和分布。结果表明,大豆食心虫成虫触角呈线型,感器包括毛型感器、耳型感器、刺型感器、腔锥型感器、栓锥形感器、鳞型感器和Bhm氏鬃毛,共7种。雌雄个体之间触角感器的分布特点基本相同,但是种类、数量有差异,存在性二型现象。

The appearance and distribution of sensilla on the antenna of Leguminivora glycinivorella Matsumura were observed with a scanning electron microscope. The results show that the antenna of L. glycinivorella adults were filiform, and were of seven types; sensilla trichodea, sensilla chaetica, sensilla squamiformia, sensilla styloconica, sensilla coeloconica, sensilla auricillica and Btihm bristles. Though the distribution of sensilla in both genders was the same, the types and numbers of sensilla differed in males and females.
