摘　　要：利用10%叶螨净WP(自制)、5%噻螨酮EC、10%浏阳霉素EC和10%溴虫腈SC共4种农药对酢浆草岩螨进行田间药效试验.结果表明:速效性最好的是10%叶螨净WP1 000倍液,药后5 d的校正防效为78.8%;试验药剂的长效性均较好,药后15 d,10%叶螨净WP1 000倍、2 000倍液,10%浏阳霉素EC 1 000倍、2 000倍液的校正防效均达到了100%,5%噻螨酮EC 1 000倍、2 000倍液,10%溴虫腈SC 1 000倍、2 000倍液的校正防效也均超过了96%.Four acaricides such as 10% Yemanjing WP （self-spotting）,5% hexythiazox EC,10% Liuyangmycin EC and 10% chlorfenapyr SC were applied to compare the effect of controlling Petrobia （Tetranychina） harti （Ewing）. The results showed that the control effect of 10% Yemanjing 1 000 times was the best after 5 d,correction control effect was 78.8＆#177; 6.1%;Long term test agents were better,10% Liuyangmycin 1 000 times,2 000 times the correction control efficiency reached 100% and 5% hexythiazox 1 000 times,2 000 times,10 % chlorfenapyr by 1 000 times, 2 000 times more than the correction of the control efficiency was 96%15 days after application.
