摘要
选用乙酰甲胺磷、甲氨基阿维菌素苯甲酸盐微乳剂联苯菊酯乳油等8种对鳞翅目幼虫高效的农药,采用树干注射法对未受害的红椿(Toona ciliata)林进行麻楝蛀斑螟(Hypsipyla robusta)预防试验。结果显示:在野外对红椿林注射不同药剂预防麻楝蛀斑螟,预防效果不同,其中,乙酰甲胺磷2倍液效果较好,防效达94.37%。
Eight kinds of pesticides, such as acephate and amino-avermectin benzoate microemulsion, were used to efficiently lepidopteran larvae. A trunk-injection method was used to test the Hypsipyla robusta control of the unredged Toona ciliata. The results showed that the acephate 2 times liquid is better,control effect of94.37%. Different agents have different control effects on H. robusta.
