蝇蛹金小蜂雌虫触角、产卵器及腹部感受器的扫描电镜观察

Scanning Electron Microscopic Observation on Sensilla of the Antennal, Ovipositor and Abdomen in Female of Pachycrepoideus vindemmiae

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.

Abstract: The antennal, ovipositor and abdomen of female wasp Pachycrepoideus vindemmiae were observed 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 sensilla, 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, chaeticum 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.
