摘 要: 通过选用350g·L-1吡虫啉悬浮剂、30%甲维毒死蜱乳油和40%氧化乐果乳油3种药剂,每种药剂设2个浓度梯度,喷洒树干对白杨透翅蛾低龄幼虫开展防治试验。结果表明:施药后20d,6种处理无显著差异,防治效果均达到90%以上;3个药剂平均虫口减退率为97.29%。350g·L-1吡虫啉悬浮剂500倍液、30%甲维毒死蜱乳油800倍液和40%氧化乐果乳油1 000倍液可用于白杨透翅蛾低龄幼虫防治。 Three kinds of agents (350 g L-1 imidacloprid suspension,30% chlorpyrifos and 40% omethoate EC) were selected.Each agent is located 2 concentration;control experiments for larvae of Parathrene tabaniformis were conducted by spraying agents on the trunk.Result shows that 20 days after application,six kinds of treat-ments has no significant difference,prevention effects being above 90%;the decreased average rate of insect popula-tion of three agents are 97.29%.500 times 350 g L-1 imidacloprid SC,800 times 30% chlorpyrifos and 1 000 times 40% omethoate EC larvae are available for combating Parathrene tabaniformis .
