中文摘要： 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。
英文摘要： 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.
