摘要
对行道树、防风林杨树采用注干农药方法防治光肩星天牛成虫、幼虫的试验研究结果表明：以长效内吸注干乳油效果最好，具有传导快，杀虫效果好，残效期长的特点。长效内吸注干乳油防治结果：行道树罩笼接虫，成虫死亡率达９２．９％，室内饲喂注于后的枝条，成虫死亡率达９９．９％，大面积防风林成虫死亡率达９４．７％，总体被害率４．４％，幼虫１～２龄死亡率达８９．８％。对比了注干农药和农药涂干的效果，防治１～２龄幼虫注干防效比涂干防效高１８．６％。注于农药方法防治光肩星天牛可提高防治效果，降低防治成本，减少对环境的污染，并可兼防其它食叶性和刺吸性害虫。
The stem injection of insecticides were applied to control the larvae andadults of A. glabripennis. The results showed that the efficiency of the long-efficient sys- tematic stem injection insecticide was best with quick conduction,high insecticidal efficiencyand long residual efficiency.The control results were as follows:adult mortality was up to92.9%in the cage-Covered,insect-inculated trees, 99.9%after feeded insecticide-in-jected shoots indcor and 94.7%in the large area windbreak forest; At the total injury rate4.4%condition,the 1-2instar larva mortality was up to 89.9%. The control efficiencies ofstem injection and stem coating of insecticide were compared, stem injection efficiencies was18.6%higher than stem coating in controling the 1-2instar larvae. Stem injction methodcould improve high control efficiency,reduce control costs,decrease environmental pollutionand also control other defoliate and piering-sucking pests.
