摘　　要：【目的】明确茶园寄生性天敌昆虫巩特桨角蚜小蜂(Eretmocerus gunturiensis)不同器官上感受器的种类、形态和分布,为巩特桨角蚜小蜂在茶园中的高效利用提供理论支持。【方法】运用扫描电镜观察了巩特桨角蚜小蜂触角、复眼、口器、雌性外生殖器、前足胫节和后足胫节上的感受器,并进行拍照保存和感器标注。【结果】巩特桨角蚜小蜂触角上的感器有板形感器、毛形感器、坛形感器、刺形感器、锥形感器、Böhm氏鬃毛,其中以毛形感器数量最多;复眼上仅有1种锥形感器,着生在复眼的小眼之间;口器上有毛形感器和刺形感器,毛形感器位于上颚,刺形感器在下颚须和下唇须末端各具1根;外生殖器有鳞形感器和刺形感器;前足广泛分布着刺形感器;后足感器主要为指形感器、毛形感器,指形感器分布在后足胫节末端,毛形感器分布广泛。【结论】本研究为巩特桨角蚜小蜂感受器的功能及感受外界信息的生理生化机制研究奠定基础。【Objective】Classification,morphology,and distribution of sensilla on Eretmocerus gunturiensis were studied to better utilize the nature predator commonly found at tea plantations.【Method】Under a scanning electron microscope(SEM),types,morphological characteristics,and distribution of various sensilla,such as antennae,compound eyes,mouthparts,ovipositors,forefoot tibia,and hind foot tibia,of the parasitic wasp,E.gunturiensis,were observed and classified.【Result】Sensilla placodea(SP),sensilla trichodea(ST),sensillum ampullaceum(SA),sensilla chaeticum(SC),sensilla basiconica(SB),and Böhm bristles(BB)were found on the antennae.SB only existed between ommatidia of the compound eye,ST and SC on the mouthparts,ST on the upper jaw,and two SCs at the end of the mandibular palpus and labial palpus.The ovipositors had squamiformic sensillum(SS)and SC;the forefoot tibia was widely distributed with SCs;and the hind foot had mainly seiisma digit-like(Sdi)and ST.【Conclusion】The SEM images detailed the appearance of various sensilla on E.gunturiensis which facilitated further studying on the function and mechanism of the organs and possible use of the wasp as a biocontrol agent against pests like Aleurocanthus spiniferus at tea plantations.
