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。
Scanning electron microscopy was used to observe the ultrastructure of the antennae, ovipositor and abdomen of Spalangia endius Walker female, and the morphology, type and distribution of the sensilla were described. There are 8 sensors on the antennae, which are Bhm’s mane, hairy sensor, prickle sensor, plate sensor, papillary sensor, thin-walled chemosensor, thick-walled chemoreceptor, There are four sensors on the abdomen: hairy sensor, thorn sensor, spore sensor and cavity sensor; there are two sensors on ovipositor: hair sensor and bell sensor; The distributions of the major sensor types on the antennae: the plate sensor and the thin-walled chemosensor are distributed in the second node to the seventh node and the rod node; the pyramidal sensor and the mane sensor are distributed in the third Salk section to the seventh section; thick-walled chemoreceptors in the rod section; thorn-shaped sensors are distributed in the handle section and stem section; hair sensor in addition to stem section, the other sections are distributed.
