摘　　要：为了明确桉树枝瘿姬小蜂雄成虫感器的外部形态特点,对桉树枝瘿姬小蜂雄成虫触角、口器、足、腹部和复眼的超微感器进行电镜扫描,并对雌、雄蜂感器进行差异比较。结果表明,在雄成虫触角上有Bhm氏鬃毛、毛形感器、刺形感器、锥形感器、耳形感器、板形感器、带形感器和乳形感器8类感器;口器上有Bhm氏鬃毛、毛形感器和刺形感器3种感器;足上有Bhm氏鬃毛、毛形感器、刺形感器和锥形感器4种感器,其前足上还具有触角清洁器;腹部共有3种感器,即Bhm氏鬃毛、毛形感器和刺形感器;而复眼上只有1种锥形感器。The sensilla of antennae,mouthparts,legs,terminal abdomen and compound eyes of the male adult of Leptocybe invasa w ere observed w ith scanning electron microscope to define the external morphological characteristics of its sensilla,and the differences betw een the sensilla of the female and male w ere compared. The result show ed 8 kinds of antennal sensilla,namely Bhm bristles,trichoid sensilla,chaeticum sensilla,basiconic sensilla,auriform sensilla,placoid sensilla,zonated sensilla and mammilliformia sensilla,w ere observed. There w ere 3 kinds of sensilla on the mouthparts,viz Bhm bristles,trichoid sensilla and chaeticum sensilla. Bhm bristles,trichoid sensilla,chaeticum sensilla and basiconic sensilla w ere observed on the legs of the males. Furthermore,there w ere antenna cleaners on the legs of the male. Bhm bristles,trichoid sensilla and chaeticum sensilla w ere found on the terminal abdomen.On the compound eyes only basiconic sensilla w ere found. The biological function of the sensilla found on the males w as discussed.
