摘　　要：茶橙瘿螨和茶跗线螨是世界性害螨,也是茶树上为害较重的害螨,爆发时会严重影响茶叶的产量和品质。目前田间防治方法大多采用的水溶性农药,考虑到抗药性等问题,因此亟需推广一种替代农药防治茶树害螨。本研究对比浙西南地区茶树害螨替代农药在田间的药效,结果表明虫螨腈和哒螨灵对茶橙瘿螨均有控制效果,防治效果随施用时间均逐渐上升,用药后14天达到最佳防治效果,最高防治效果分别为86.40%与57.07%。虫螨腈防治效果最好,喷药后三周,校正防效仍在80%以上。Acaphylla theae(Watt)and Polyphagotarsonemus latus(Banks)are worldwide harmful mites and they are also harmful to tea plants by seriously affecting the yield and quality of tea.At present,water-soluble pesticides are used to control them.Considering to the pesticide resistance and other factors,it is urgent to promote an alternative pesticide to control pest mites on tea plants.This study investigated the efficacy of alternative pesticides to pest mites on tea plants in southwestern Zhejiang.The results showed that Chlorfenapyr and Pyridaben had control effects on Acaphylla theae(Watt).They reached the best control effect at 14th day after field application,with the highest control effects being 86.40%and 57.07%,respectively.Chlorfenapyr had a better control effect than Pyridaben.Three weeks after field application,the corrected control effect was still above 80%.
