摘　　要：应用扫描电镜对蝇蛹金小蜂Pachycrepoideus vindemmiae Rondani雌虫触角、产卵器及腹部末端上的感受器(简称感器)进行了观察.结果表明,雌蜂触角上有8种感受器类型,分别为Bhm氏鬃毛、板形感器、锥形乳头状感器、薄壁化学感器、厚壁化学感器、毛形感器、刺形感器和感觉孔;腹部上发现3种感受器类型:毛形感器、刺形感器和芽孢形感器;产卵器上分布了4种感器类型:毛形感器、刺形感器、芽孢形感器和分泌孔.本研究还对感器的形态、数量及分布进行了描述.The antennal , ovipositor and abdomen of female wasp Pachycrepoideus vindemmiae were ob-served with scanning electron microscopy （ SEM ） .The results indicated that eight types of sensilla , namely B？hm bristles, chaeticum sensilla,trichodea sensilla, placoid sensilla, basiconic mastoid sensil-la, thick walled chemoreceptor , thin walled chemoreceptor and sensory pore , were found on the surface of the antenna .Three types of sensilla , namely trichodea sensilla , chaeticum sensilla and bud-shaped sensilla were found on the terminal abdomen .Four types of sensilla , namely trichodea sensilla , chaetic-um sensilla, bud-shaped sensilla and sensory pore , were found on the ovipositor.The types, numbers, morphological characteristics and the relative positions of these sensilla were also depicted .
