为了了解自然界中几种寄生蜂的相互关系，对几种共存的多食性寄生蜂的生殖生物学进行了比较。本文研究了日本姬小蜂、白环姬小蜂、油桐姬小蜂、大斑姬小蜂、金龟子姬小蜂和金龟子姬小蜂6种姬小蜂的发育历期、寿命、雌卵数、雌卵数、羽化率和性比等生殖性状。松村茶Galleria mellonella（L.），甘蓝夜蛾，和间斑螟Plodia interpunctella Hubner（鳞翅目）为寄主。各蜂种雄蜂的发育历期和寿命均显著短于雌蜂。雌蝇卵巢管和成熟卵的平均数量均较少。寄主接受，羽化率，和性比的寄生蜂变化显着，无论是寄生蜂的种类或对主机的种类。我们的研究结果表明，寄主利用不同的六种寄生蜂。
The reproductive biology of several coexisting polyphagous parasitoids was compared in order to understand the interactions among them in nature. Developmental period, longevity, number of ovarioles and mature eggs per female, emergence rate, and sex ratio were examined as an index of reproductive characters in six pimpline ichneumonid parasitoids, Pimpla nipponica Uchida, P. alboannulata Uchida, P. luctuosa Smith, P. pluto Ashmead, Itoplectis naranyae Ashmead, and I. alternans spectabilis Matsumura. Galleria mellonella (L.), Mamestra brassicae L., and Plodia interpunctella Hubner (Lepidoptera) were used as hosts. Developmental period and longevity of males were significantly shorter than those of females in all the parasitoid species. Both average numbers of ovarioles and mature eggs per female were relatively few in all the parasitoid species. Host acceptance, emergence rate, and sex ratio of parasitoids varied markedly, depending either on the parasitoid species or on the host species. Our results suggest that host utilization differs among the six parasitoid species.
