通过四种常用农药对桑树朱砂叶螨进行防治,观察防治效果以及对桑蚕的残效期。结果表明：30%氧化乐果乳油1000倍液和25%甲氰菊酯·辛硫乳油500倍液防治效果最好,95%蚧螨灵乳油和30%氧乐果乳油对桑蚕的残效期最短。建议防治桑树朱砂叶螨时要注意药物选择,即在养蚕生产前选用30%氧化乐果乳油1000～2000倍液防治;在早春和非养蚕季节选用25%甲氰菊酯·辛硫乳油500～1000倍液进行防治。
通過四種常用農藥對桑樹硃砂葉螨進行防治,觀察防治效果以及對桑蠶的殘效期。結果錶明：30%氧化樂果乳油1000倍液和25%甲氰菊酯·辛硫乳油500倍液防治效果最好,95%蚧螨靈乳油和30%氧樂果乳油對桑蠶的殘效期最短。建議防治桑樹硃砂葉螨時要註意藥物選擇,即在養蠶生產前選用30%氧化樂果乳油1000～2000倍液防治;在早春和非養蠶季節選用25%甲氰菊酯·辛硫乳油500～1000倍液進行防治。

By applying four kinds of commonly used pesticides to prevent Tetranychus cinnabarinus, the preventive effect and the residualife were observed. The results showed that 1000 times of flolimat missible and 500 times of fenpropathrinoPhoxim emulsifiable concentrate by 50% had the best preventive effect , and Mite ec pest spirit by 95% and flolimat missible by 30% had the shortest residualife. Therefore, it is suggested to choose the right pesticide when preventing Tetranychus cinnabarinus, namely, to apply 1000 to 2000 times of flolimat missible by 30% at silkworm rearing season; to apply 500 to 1000 times of fenpropathrinoPhoxim emulsifiable concentrate by 25% at early spring and non-silkworm rearing season.
