1989～1990年,在经过室内毒力测定证明溴灭菊酯对马尾松毛虫有很高毒效的基础上,用其进行了林间和飞机大面积防治马尾松毛虫试验。防治结果表明,林间喷药对3～4龄马尾松毛虫幼虫防效达96.5%～100%;飞机大面积喷洒,对4～5龄马尾松毛虫幼虫防效达87%～95.08%。与此同时,对松实小卷蛾和松梢螟兼治的效果分别为87.91%和71.5%。
From 1989 to 1990, on the basis of indoor toxicity test, it was proved that there was a high toxic effect of clomathrin on Dendrolimus punctatus, and the large-scale control test of Dendrolimus punctatus in the forest and aircraft was conducted. The results of prevention and treatment showed that the forest spraying efficiency of 96.5% -100% against 3 ~ 4-year-old Dendrolimus punctatus larvae was large and the spraying efficiency was 87% -95.08% against 4-5-year-old Dendrolimus punctatus larvae. In the meantime, the effects of treating both pine moth and pine needles were 87.91% and 71.5%, respectively.
