| 摘 要： | 在室内运用浸渍法和叶片残毒法测定了4种杀螨剂对二斑叶螨抗性种群不同发育阶段的致毒作用。结果表明：阿维菌素对雌成螨的毒力最高，LC50为0．0876mg；L^-1；其次为三唑锡和白红螨清，LC50分别为1．2826mg·L^-1和1．4369mg·L^-1。对卵的毒力也是阿维菌素最高，LC50为0．4951mg·L^-1；其次为螨及时和白红螨清，LC50分别为1．0749mg·L^-1和4．6578mg·L^-1。对二斑叶螨的室内控制效果依次为阿维菌素〉三唑锡〉白红螨清〉螨及时。

| Abstract: | The toxicities of four kind Of acaricides and their mixtures to Tetranychus urticae Koch were measured by both slide-dip method and leaf-dip method in the laboratory. The results showed that avermectin had the highest toxicity to female adults, LC50 was 0.0876 mg·L^-1 ; Azocyclotin and Baihongmanqing had higher toxicities, LC50 were 1.2826 mg·L^-1 and 1.4369 mg·L^-1. While, the acaricides which had the highest toxicity to eggs also was avermectin, LC50 was 0.4951 mg· L^-1; Manjishi and Baihongmanqing had higher toxicities, LC50 were 1.0749 mg· L^-1 and 4.6578 mg. L^-1 The orders of four kind of acaricides from high to low were avermectin〉Azocyclotin〉Baihongmanqing〉Manjishi. |
