摘　　要：应用扫描电镜技术,对沙蒿大粒象Adosomus sp.触角感器的类型、分布、数量以及雌雄之间的差异进行了详细研究。结果表明:沙蒿大粒象触角上共有5种感器类型,包括板形感器(Ⅰ、Ⅱ和Ⅲ型)、毛形感器和刺形感器。触角各节的感器类型和分布差异较大,以板形感器的分布最广、数量最多,在触角各节均有分布;刺形感器分布在索节第1亚节和棒节,而毛形感器仅分布在棒节且数量较少。雌雄触角的感器类型及分布基本一致,但分布数量上雄虫明显多于雌虫。The antennal sensilla of Adosomus sp.（Coleoptera： Curculionidae） were studied with a scanning electron microscope to determine their type,quantity,distribution and sexual dimorphism.Five types of sensilla were identified,including placoid（Ps,typeⅠ,Ⅱand Ⅲ）,chaetica（Ch） and trichoid（T）.These types of sensilla differ markedly in their distribution;Ps are the most abundant and widely distributed;Ch are distributed in the first section of the funicle and the club,and T are the least abundant and confined to the club.The types and distribution of sensilla are basically the same in males and females,except that they are significantly more abundant in males.
