中文摘要： 调查西双版纳地区黄琼蚁Oecophylla smaragdina Fabricius对橡胶盔蚧Para saissetia nigra (Nietner)种群数量和寄生蜂的影响。结果表明： 黄琼蚁对橡胶盔蚧种群消长及寄生蜂均有影响。“有蚂蚁”枝条上介壳虫种群数量 显著高于 “无蚂蚁”枝条。“有蚂蚁”枝条介壳虫死亡率和寄生蜂都显著低于“无蚂蚁”枝条。说明 黄琼蚁的存在影响了橡胶树介壳虫的种群繁殖率和死亡率。建议在今后综合防治中 ，充分利用蚂蚁与橡胶树介壳虫关系。通过驱逐橡胶树上的蚂蚁来有效遏制介壳虫的发生。
英文摘要： The effect of Oecophylla smaragdina Fabricius on Parasaissetia nigra (Nietner) pop ulation dynamics was investigated in Xishuangbanna. The results showed that O. smaragdina may influence P. nigra population dynamics and its parasitic wa sps. Population size of P. nigra was significantly higher on the branches of trees with ants than those without ants, and mortality and amount of parasitic wasps were significantly lower on trees with ants than those without ants. It wa s suggested that the interaction of O. smaragdina and P. nigra should be applied in IPM, in which ants should be excluded to control P. nigra.
