摘　　要：对松突圆蚧优势本土寄生蜂——友恩蚜小蜂Encarsia amicula林间人工释放后的扩散能力进行了调查。结果表明:友恩蚜小蜂在林间释放后,360d的寄生扩散半径可达到200m,在山地横向扩散速度快于纵向扩散。环境条件的变化对该蜂繁殖量影响较大,而对扩散速度没有影响。The dispersal ability of Encarsia amicula, a dominant native parasitoid of Hemiberlesia pitysophila, in the forest was investigated. The results showed its dispersal radius was 200 m 360 days after the release and the speed of its traverse dispersal was quicker than that of vertical dispersal in hills. The changes of environmental conditions had great influence on the parasitoid population, but no influence on the dispersal speed
