中文摘要：
中黑盲蝽Adelphocoris suturalis Jakovlev是目前我国棉花上的一种重要害虫。采 用扫描电镜技术对其触角形态和感器进行观察，结果表明：中黑盲蝽雌雄成虫及若虫触角 上分布4种类型的感器，分别为刺形、毛形、锥形和蒲姆氏鬃毛，且这些感器不存在性二型现象。其中毛形感器有2个类型，若虫触角上的部分蒲姆氏鬃毛组合成弧形感觉簇。
英文摘要： Adelphocoris suturalis Jakovlev is a most important pest of cotton in China at p resent. Antennal morphology and sensilla of A. suturalis were studi ed w ith scanning electron microscopy. The results showed that four types of sensilla were observed on the antenna of adults and nymphae, including sensilla chaetica , sensilla trichodea, sensilla basiconca, and bahm bristles, and no morphologic a l difference was found in these sensilla between male and female adults. There were two types for sensilla trichodea. Some bohm bristles formed sensilla cluste r on antenna of nymphae.
