摘要:

白背飞虱Sogatella furcifera (Horváth)是水稻的主要害虫之一。采用扫描电镜技术对白背飞虱触角感器进行了观察。结果表明,白背飞虱成虫触角上有3种类型的感器——毛形、刺形和耳状感器,以及由毛形和耳状感器组成的一种菊花状的感器簇,且这些感器在雌雄中不存在二型性。同时,对其高龄若虫触角感器的观察也表明,白背飞虱触角感器的数量随若虫龄期的增加而增加,且在羽化为成虫时数量会大幅度的增加。

Abstract:

Sogatella furcifera (Horváth) is one of most important pests of rice. Morphology of antennal sensilla of S. furcifera was observed with scanning electron microscope. Three types of sensilla and a kind of sensilla cluster were observed on the antenna of the adult, and no morphological difference was found in these sensilla between the male and female adults. The number of sensilla increased with the development of S. furcifera nymph, especially after ecdysis and eclosion.
