摘　　要：2013―2014年对新疆巴州地区枣大球蚧Eulecanium gigantea（Shinji）进行寄生蜂调查,发现一种寄生率较高的小蜂——等缘蚧金小蜂Eunotus aequalivena Xiao et Huang,平均雌雄性比为1.51：1。通过对枣大球蚧发生密度较大的4种主要寄主植物白榆、黄榆、紫穗槐和灰枣树上的寄生蜂进行调查,发现等缘蚧金小蜂在田间的自然寄生率为0-21.00%,其中白榆、黄榆和紫穗槐3种树上对枣大球蚧的寄生率为14.37%-21.00%,但灰枣树上的寄生率仅为0。The parasitic wasps on Eulecanium gigantea in Bayingolin Mongolia Autonomous Prefectre of Xinjiang were investigated during 2013—2014. Eunotus aequalivena Xiao et Huang（Hymenoptera： Chalcidoidea： Pteromalidae） was found to be another highly parasitic rate species to E. gigantea. The average sex ratio was 1.51：1 in farming area. The parasite rate of E. aequalivena on E. gigantea was investigated on four host plants of E. gigantea, Ulmus pumila L., Ulmus macrocarpa Hance, Amorpha fruticosa L. and Ziziphus jujuba cv. Huizao, respectively. The result shows that the natural parasitic rate ranged from 0 to 21.00%. Among the four hosts plants, the parasitic rate of Z. jujuba was only 0 contrast to other three＇s 14.37%―21.00%.
