摘　　要：应用扫描电镜技术观测了茶棍蓟马若虫、蛹、雌雄成虫触角感器的类型、分布及超微结构。结果表明,各种虫态的茶棍蓟马触角上共存在9种感器:B?hm氏鬃毛(BB)、钟形感器(SCa)、锥形乳头状感器(BMS)、刺形感器(SCh)、锥形感器(SB)、腔锥形感器(SCo)、腔形感器(SCav)、耳形感器(SA)和特殊结构感器(US)。其中,刺形感器分3种亚型,锥形感器分4种亚型。若虫、蛹、雌、雄成虫的触角感器在触角上的种类和分布有较大的差异,雌虫上具8种感器,无锥形乳头状感器;雄虫上着生7种,缺少锥形乳头状感器和腔形感器;若虫上感器种类有8种,无耳形感器,独具锥形乳头状感器;蛹的感器类型及数量最少,只有2种,即刺形感器和锥形感器。The type, distribution and ultrastructure of sensilla on the antennae of nymph, pupa, adult female and male of Dendrothrips minowai Priesner thrips were observed under the scanning electron microscope （SEM）. Results showed that nine kinds of sensors existed on D. Minowai thrips, which were B？hm bristles, sensilla campaniformia, basiconic mastoid sensillum, sensilla chaetica, sensilla basiconica, sensilla coeloconica, sensilla cavity, sensilla auricillia and unusual sensillum. The sensilla chaetica and sensilla basiconica contained three and four subtypes, respectively. The type and distribution of sensilla significantly varied among different developmental stages： 1） Eight types of sensilla except basiconic mastoid sensillum were existed on the adult female. 2） Seven types of sensilla were existed on adult male other than basiconic mastoid sensillum and sensilla coeloconica. 3） The nymph possessed eight types of sensilla except sensilla auricillia, and with distinctive basiconic mastoid sensillum. 4） The types and number of sensilla on pupa were the least, only with sensilla chaetica and sensilla basiconica.
