Notes: 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 a highly parasitic species on 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 0 in contrast to other three which were 14.37%―21.00%.
