摘　　要：应用花绒寄甲和管氏肿腿蜂防治杨树光肩星天牛试验,结果表明：2种天敌对光肩星天牛均能起到很好的防治效果,联合应用效果更佳.在不同释放模式下,林间有虫株率均分别下降了20.84％ ～43.71％,其中联合应用区域有虫株率仅为37.5％,下降显著,较对照区有虫株率下降了52.5％.同时发现2种天敌对不同位置的寄主具有一定的选择性,其中对南向枝干上的寄主寄生几率最低.The experiment of releasing Dastarcus helophoroides and Scleroderma guani to control Anoplophora glabripennis, showed that these natural enemies could both play a good effects, and the effect of combined application was better. The percentage of insectinfected trees descended 20.84% -43.71% with different release mode. The combined application decreased significantly insect - borne tree ratio to 37.5% only, 52.5% lower than that in control area. Meanwhile, the ex- periment found that these natural enemies had certain a selectivity to the host at different positions, with the parasitization rate of the south branch lowest.
