2种不同类型烟雾剂喷烟防治杨树食叶害虫药效试验

对2种不同类型烟雾剂2%阿维菌素油烟剂和4.5%高效氯氰菊酯乳油利用喷烟机喷烟防治杨树食叶害虫的防治成本、效果及污染情况进行了对比试验。试验结果表明,2种烟雾剂的杀虫效果都很好,害虫死亡率均达95%以上,但防治成本前者比后者低,而且后者对人畜有较高的毒性,杀伤天敌,对环境产生污染,而前者属于抗生素类杀虫杀螨剂,对虫螨具有胃毒和触杀作用,对环境无污染,不杀伤天敌,防治效果好,应大力推广使用阿维菌素油烟剂防治害虫。

Efficacy Test of the Aerosol Spraying of Two Type Aerosol Poplar against the Defoliator in Poplar

The experement was conducted on the control cost,effect and the pollution situation with two types of aerosol polar,2% jet smoke fumes abamectin and 4.5% doses of beta-cypermethrin EC,using fog machine to speay.The results showed that fine effect was observed in both aerosol,and the mortality of insect was above 95%,but the latter was more toxic,harm to natural enemy and caused pollution.While the former belonged to a category of the antibiotic acaricides insecticide on insects and mites with gastric toxicity poisoning effect,environment pollution-free,no harm to anti-predators,good effect and lower control cost.So,it should be popularized and applied.
