摘　　要：利用扫描电镜观察了同属的桑天牛卵啮小蜂(Aprostocetus prolixus)和桑天牛长尾啮小蜂(Aprostocetus fukutai)的触角感器,对这两种寄生蜂触角感器的种类、形态、数量及分布进行了描述,并对雌雄两性触角之间的差异做了比较。结果发现,在两种寄生蜂的触角上着生着6种感器,分别为指形感器、板状感器、毛形感器、坛形感器、刺形感器、蒲姆氏鬃;两种桑天牛卵寄生蜂触角感器的种类、数量及分布模式在种间没有明显差异,但在种内雌雄个体间差异较为显著。研究结果将有助于揭示桑天牛卵寄生蜂的寄生机制。The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too. The results indicated that there were six types of sensilla, namely, finger-like sensilla, platcodeum sensilla, trichoid sensilla, ampullaceous sensilla and chaetic sensilla on the antenna of two wasps. The type, number,and distribution patterns of the antennal sensilla were similar in the two species, but the differences between two sexes were significant. These results are helpful to reveal the parasitic mechnism of parastic wasps.
