摘要
桦三节叶蜂是近几年来在湖北省神农架林区危害红桦的重要害虫。野外调查和室内饲养观察的研究结果表明,桦三节叶蜂在湖北省神农架地区1年发生1代,以幼虫取食叶片,以预蛹在寄主树干皮内茧中越冬;寄生性天敌主要有寄蝇、姬蜂和大腿小蜂3类,天敌对叶蜂茧的寄生率为8%～14%,其中以寄蝇的数量最多。利用3%高渗苯氧威乳油、1.2%烟碱.苦参碱乳油等仿生农药对叶蜂幼虫进行喷烟喷雾具有良好的防效。
The biological characteristics of Arge pullata Zadd,one of important deforliators of Betula albo-sinensis in Shennongjia Forest Region,were preliminarily studied in the field and laboratory.The results showed that it occurred one generation each year and overwintered as prepupae in the chrysalis under the bark of the host tree.There were 3 kinds of parasitic enemy of the sawfly including parasitic fly,ichneumon fly and thigh wasps,the natural parasitization of the prepupae was 8%-14%,and the parasitic fly was the dominant natural enemy.The pest could be controlled effective by using high permeation fenoxycarb 3% EC,matrine-nicotine 1.2% EC against the pest by means of spraying or fogging.
