蠼螋Labidura riparia Pallas成虫触角感器的超微结构观察

革翅目昆虫是河南省中部地区鳞翅目害虫的一类重要捕食性天敌昆虫,在农业无公害化的发展趋势下,具有广阔的应用前景.本研究采用扫描电子显微镜技术,对其中的蠼螋科,蠼螋属中的蠼螋雌、雄成虫触角感器的形态特征进行了研究,结果表明:蠼螋触角呈丝状,由柄节、梗节和鞭节组成,雌、雄成虫鞭节分别由26和30个亚节组成.共有8种感器类型:...

Observation on the Ultrastructures of Labidura riparia Pallas Adult Antennal Sensilla

Dermoptera insects are a group of important predatory insects in central region of Henan Province and show a high application potential in the development of pollution-free agriculture. In this study, morphology and ultrastructure of antennal sensilla of Labidura riparia Pallas were observed with scanning electron microscope. Our results showed that the antenna of female and male adult of L. riparia is filamentous and composes of scapus, pedicel and flagella. The flagellum consists of 26 and 30 segments in female and male adults, respectively. There are 8 types of antennal sensilla in the antenna of female and male adult, i.e., trichode, chaeticum, gemmiformium, squamiformia, styloconica, BÖhm bristles, ampullaceum, and cavitata-peg. The types and numbers of sensilla differ between subunits of antenna. The sensilla on flagella are much more abundant than on scapus and pedicel. The sensilla types and numbers on male antenna are much more than those on female antenna. Sensilla gemmiformium is specific to the male adult.
