摘　　要： 利用扫描电镜观察了蝇蛹俑小蜂Spalangia endius Walker雌虫触角、产卵器及腹部的超微结构,描述了其感器的形态、类型和分布。触角上共有8种感器,分别为Bhm氏鬃毛、毛形感器、刺形感器、板状感器、锥形乳头状感器、薄壁化学感受器、厚壁化学感受器和鬃形感器;腹部上有4种感器:毛形感器、刺形感器、芽孢形感器和腔形感器;产卵器上有两种感器:毛形感器和钟形感器;各主要感器类型在触角上的分布:板形感器和薄壁化学感受器分布在第二索节至第七索节和棒节;锥形乳头状感器和鬃形感器分布在第三索节至第七索节;厚壁化学感受器在棒节;刺形感器分布于柄节和梗节;毛形感器除了柄节外,其它各节均有分布。 The antennal, ovipositor and abdomen ultrastructures were observed with scanning electron microscopy （SEM） for female Spalangia enditrs Walker. The types, numbers, morphological characteristics and the relative positions of these sensilla were depicted. The results indicate that eight types of sensilla, namely BOhm bristles, chaeticum sensilla, trichodea sensilla, placoid sensilla, thick walled chemoreceptor, bristle sensilla, thin walled chemoreceptor and basiconic mastoid sensilla, were found on the surface of antenna. Four types of sensilla, namely trichodea sensilla, chaeticum sensilla, sensilla gemmiformium and coeloeonica sensilla were found on the terminal abdomen. Two types of sensilla, namely trichodea sensilla and sensilla campaniformia were found on the ovipositors. Placoid sensilla and thick walled chemoreceptor mainly distributed on second funicle to seventh funicle and the club, basiconic mastoid sensilla and bristle sensilla located in third funicle to seventh funicle, thick walled chemoreceptor distributed on the club, chaeticum sensilla located in scape and pedicel, trichodea sensilla located on every segments except scape.
