树干注射不同药剂防治麻楝蛀斑螟试验

Trunk Injection of Different Pesticides to Control the Larvae of Hypsipyla robust

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 of 94.37%.Different agents have different control effects on H.robusta.
