【摘要】 为了探索对吉林西部地区杨树防护林2种蛀干害虫的最佳防治技术，以白杨透翅蛾、青杨天牛为研究对象，通过林间控制变量试验，对比4种药剂虫孔注射和喷雾施药的防治效果，分析最佳防治措施和最适药剂。研究结果表明：虫孔注射的防治效果比喷雾施药略好，虫孔注射防效最佳的药剂为3%高渗苯氧威乳油（3 000倍液），喷雾施药防效最佳的药剂为1.5%苦参碱可溶液剂（1 000倍液）。1.5%苦参碱可溶液剂是防治白杨透翅蛾、青杨天牛成虫的最佳药剂。1.8%阿维菌素乳油、阿维·苏云菌可湿性粉剂和3%高渗苯氧威乳油也具有良好的防效，生产中可根据实际情况选择使用。更多还原

【Abstract】 In order to explore the optimal control techniques for two types of stem boring insects in poplar protective forests in western Jilin, taking Paranthrene tabaniformis and Saperda populnea as research objects, through forest controlled variable experiments, the control effects of two control measures and four insecticides were compared, and the optimal control measures and suitable biological pesticides were analyzed. The results showed that the control effect of wormhole injection was better than that of spray. The best insecticide for wormhole injection was fenoxycarb 3% EC(3 000-fold diluent), and the best insecticide for spray was matrine 1.5% SL(1 000-fold diluent). Matrine 1.5% SL was the best insecticide in four insecticides for the adult of Paranthrene tabaniformis and Saperda populnea. Avermectin 1.8%EC, avermectin·Bacillus thuringiensis WP, fenoxycarb 3% EC also had good efficacies, and could be selected and used according to specific situations in production practice.更多还原
