摘　　要：【目的】盛冈纹瘿蜂是在栎树上形成虫瘿危害的重要害虫。明确盛冈纹瘿蜂雌虫的超微形态,主要包括复眼、触角、口器、足和产卵器上感器的种类、数量和分布等,为瘿蜂综合防治与利用提供理论依据。【方法】运用扫描电子显微镜对雌虫的超微形态结构进行观察。【结果】盛冈纹瘿蜂的复眼由多个小眼组成,其间有锥形感器。雌虫触角由柄节、梗节和鞭节组成,鞭节分为11亚节,柄节呈漏斗状,梗节较短呈球状。鞭节1—3亚节呈长圆柱状,末节粗壮、端部渐尖,其余呈短圆柱状。触角上分布有毛形感器、刺形感器、锥形感器、板形感器和腔锥形感器5种感器,其中毛形感器的数量最多、分布最广泛。板形感器较为特殊,形状宽长,表面光滑,分布在第3—11亚鞭节上。口器为咀嚼式口器,下颚须发达,密被毛形感器。足上有许多毛形感器和刺形感器;产卵器上分布有毛形感器、刺形感器、锥形感器、耳形感器和火山形感器。【结论】盛冈纹瘿蜂雌虫复眼、触角、口器、足和产卵器上有各种不同类型的感器,感器的功能与瘿蜂栖息、取食、繁殖等一系列生理活动密切相关。【Objective】Andricus moriokae is an important pest that induces galls on oak.This study aimed to clarify the ultramorphology of the female A.moriokae,especially for the types,quantity,and distribution of sensilla on the compound eyes,mouthpart,antennae,legs and ovipositor.【Method】The ultramorphology of female A.moriokae was observed under the scanning electron microscope.【Result】It was found that the compound eyes of A.moriokae are composed of a number of ommatidia with conical sensilla.The antennae of female insects are composed of a scape,a pedicle and 11 flagellomeres.The scape is funne-shaped,and the pedicle is short and globular.The first three flagellomeres are long columnar,and the last one is a bullet-shaped.The rest flagellomeres are short columnar.There are 5 kinds of sensillum distributed on the antennae of the gall wasp,including sensilla trichodea,sensilla chaetica,sensilla basiconica,sensilla placodea and sensilla coeloconica,of which the number and distribution of sensilla trichodea are the most extensive.The sensilla placodea is particular in the flagellomeres 3-11,with long and wide shape and smooth surface.The mouthparts are developed with sensilla trichodea on the maxillary palps.The legs are fluted with sensilla chaetica and sensilla trichodea.The ovipositor bears sensilla trichodea,sensilla chaetica,sensilla basiconica,sensilla auricillica and sensilla volcanica.【Conclusion】There are different types of sensilla distributed on the compound eyes,antennae,mouthpart,legs and ovipositor of the female of A.moriokae.The functions of all kinds of sensory organs are closely related to a series of physiological activities such as roosting,feeding and reproduction of A.moriokae.This study may provide a theoretical basis for the comprehensive control and utilization of A.moriokae.
