摘　　要：使用15%哒·阿维热雾剂和15%克螨特热雾剂2种药剂进行防治橡胶六点始叶螨的药效试验结果表明:施药3 d后,克螨特热雾剂防效为76.68%,哒·阿维热雾剂防效为89.33%,处理间差异显著,哒·阿维热雾剂的速效性优于克螨特热雾剂;施药后7 d后,克螨特热雾剂防效为83.43%,哒·阿维热雾剂的防效为87.62%,处理间差异不显著;药后15 d,哒·阿维热雾剂还保持在85%以上,而克螨特热雾剂的防效降至63.35%,哒·阿维热雾剂的持效期显著优于克螨特热雾剂。The efficacy trials of two hot fogging concentrate showed that the mite population was respectively reduced 76.68% and 89.33% on the third day after treatment of 15% propargite and 15% abamectin, obvious difference between the two treatments. Abamectin better than propargite; The mite population was respectively reduced 83.43% and 87.62% on the seventh day after treatment of 15% propargite and 15% Abamectin, no significant difference between the two treatments. On the fifteenth day after treatment, the mite population was reduced at 85% or more by 15% Abamectin, but the mite population was reduced at 63.35% or less by 15% propargite.
