摘要：

为研究短角曲姬蜂成虫触角的外部形态及其感觉器的种类问题,通过扫描电镜观察,对短角曲姬蜂雌、雄成虫触角及感觉器进行差异性比较。观察表明,短角曲姬蜂成虫触角为鞭状,触角由柄节、梗节和鞭节3个部分组成。雌性成虫触角鞭节21个亚节,雄性成虫触角鞭节25个亚节。短角曲姬蜂成虫触角上有刺型、板型、毛型、腔锥形乳突状、钟形和B?hm氏鬃毛6种类型感觉器。短角曲姬蜂雌、雄成虫触角感觉器在形态和密度上存在性二型现象。

Abstract:

To study the external morphology and the type of sensilla of adult Scambus brevicornis’s antennae, the sex difference was compared by scanning electron microscope. The results showed that the antennae of the adult S. brevicornis was flagelliform and the antennae were composed of scape, pedicle and flagellum. The female adult had 21 subsegments and the male adult had 25 subsegments. There were six sensillas on the adult antennae, including sensilla trichodea, sensilla placodea, sensilla coeloconica, sensilla chaetica, B?hm bristles and sensilla campaniformia. There were sexual differences in the density between male and female adults.

Key words: Scambus brevicornis, antenna, sensilla, morphology, scanning electron microscopy
