摘要
利用管氏肿腿蜂防治新疆杨光肩星天牛幼虫,测定管氏肿腿蜂对光肩星天牛幼虫的寄生率。试验确定,在放蜂15 d后,光肩星天牛幼虫开始停止排粪,管氏肿腿蜂对光肩星天牛幼虫寄生率为46.6%,防治效果为45.2%。管氏肿腿蜂对新疆杨农防林带中的光肩星天牛幼虫有一定的防控作用。
Scleroderma guani Xiao et Wu was a parasitic hymenoptera of Anoplophora grabripennis. It was released artificially for controlling the larvae ofAnoplophora grabripennis on Populus alba var. pyramidalis Bge. And the parasitism was investigated after a few days. The results showed that after releasing Scleroderma guani Xiao et Wu for 15 days, the larvae of Anoplophora grabripennis stopped to defecate. The parasitic rate of Scleroderma guani Xiao et Wu was 46. 6%, and the controlling effect was 45.2%. Releasing Scleroderma guani Xiao et Wu can control Anoplophora grabripennis in farmland shelter belt of Populus alba var. pyramidalis Bge.
