摘　　要：榕树褐软蚧的寄生蜂在玉溪有9种,在昆明有4种,其中优雅岐脉跳小蜂(Diversinervus elegans Silvestri)和蜡蚧啮小蜂(Tetrastichus ceroplasteae Girault)是主要寄生蜂,在玉溪占寄生蜂总数的60.36%,在昆明占寄生蜂总数的80.48%.在方位上,寄生蜂在榕树树冠东面、北面的寄生率高于西面、南面,以北面为最高,南面为最低.通过Iwao的回归分析,褐软蚧寄生蜂种群在榕树上的空间分布型为聚集分布.Nine species of parasitic wasps of Coccus hesperidum in Yuxi and four species of parasitic wasps of Coccus hesperidum in Kunming were identified.Diversinervus elegans and Tetrastichus ceroplasteae were the two main parasitic wasps,occupying 60.36% in Yuxi and 80.48% in Kunming.The spatial distribution of parasitic wasps population was different on different orientation of figs.The parasitic rate in average was higher on the north and east side than that on the south and west side,and highest on the north si...
