【摘要】：霍氏啮小蜂Tetrastichus howardi(Olliff)是许多鳞翅目害虫的群居性蛹寄生蜂。为分析霍氏啮小蜂成虫产卵器和交配器上与成虫产卵和交配有关的感受器类型,本文利用扫描电镜对霍氏啮小蜂成虫产卵器和交配器的超微结构进行了观察。在霍氏啮小蜂成虫产卵器上共发现了7种感受器,分别是毛形感器1(TS1)、毛形感器2(TS2)、刺形感器2(CH2)、分泌毛孔(SP)、栓锥形感器1(SS1)、栉齿状感器(DS)、浅凹形感器(SD)和火山形感器(VS)。交配器上共发现6种感受器官,分别是栓锥形感器2(SS2)、火山形感器(VS)、表皮孔(CP)、鸡冠状结构(Crs)、钟形感器(CAS)和毛形感器3(TS3)。结果表明霍氏啮小蜂可通过产卵器和交配器上感受器获得与寄主和配偶相关的信息,进而调控产卵行为和交配行为。
[Abstract]:Tetrastichus howardi (Olliff) is a colony parasite of many Lepidoptera pests. In order to analyze the types of receptors related to adult oviposition and mating on the ovipositor and crossover, the ultrastructure of the ovipositor and the cross orchestration was observed by scanning electron microscope (SEM). Seven kinds of receptors were found on the ovipositor of Elastomus hominis, namely, hairy sensilla 1 (TS1), hairy sensilla 2 (TS2), spinous sensilla 2 (CH2), and secretory pore (SP), corrugated sensilla 1 (SS1). Ctenoid sensilla (DS), shallow concave sensilla (SD) and volcanic sensilla (VS). A total of 6 kinds of sensory organs were found on the transponder, namely, corrugated sensilla 2 (SS2), volcanic sensilla (VS), epidermis pore, (CP), coronal structure (Crs), bell-shaped sensilla (CAS) and hairy sensilla 3 (TS3). The results showed that the host and spouse information could be obtained by the ovipositor and the receptor on the ovipositor, and then the oviposition behavior and mating behavior could be regulated.
