摘　　要：评价了40个常规草莓品种对二斑叶螨、西花蓟马和根腐病的抗性,同时测定了9种药剂对二斑叶螨的田间防效。结果表明,综合抗虫性较强的品种有黑珍珠、红珍珠、红星、紫金早玉等9个品种,田间对根腐病抗性较强的有丰香、越心、粉玉等3个品种。药效试验结果表明,5%甲氨基阿维菌素苯甲酸盐微乳剂对二斑叶螨具有良好的防效,药后1~5 d的防效为87.23%~98.78%,速效性和持效性俱佳,可推荐用于草莓田间二斑叶螨的防治。40 conventional strawberry varieties were evaluated for their resistance to Tetranychus urticae,Frankliniella occidentalis and root rot,and the field control effects of 9 insecticides against T.urticae were tested.The results showed that among the 40 strawberry varieties tested,there were 9 varieties with strong comprehensive resistance to insect pests,including‘Black Pearl’‘Red Pearl’‘Hongxing’and‘Zijinzaoyu’,while the varieties with strong resistance to root rot in the field were‘Fengxiang’‘Yuexin’and‘Fenyu’.Field efficacy test results showed that 5%emamectin benzoate microemulsion had the best control effect on T.urticae,and the control efficacy was 87.23%to 98.78%in 1-5 days after treatment,which indicated good rapidity and persistence,it could be recommended for the control of T.urticae in strawberry production.
