| 叶螨和蚜虫是草莓生产中的重要害虫, 为减少化学农药使用同时提高防治效果, 本研究选择几种生物源农药对草莓叶螨和蚜虫进行防治效果比较。研究结果表明, 对叶螨, 1.8%阿维菌素微乳剂(ME) 1 400倍液防治效果最佳, 药后7 d防治效果达81.15%, 显著高于其他处理; 2.5%鱼藤酮乳油（EC） 600倍液防治效果最差, 药后7 d防治效果为46.87%。对蚜虫, 2.5%鱼藤酮EC 400倍液防治效果最佳, 药后7 d防治效果达85.08%, 1.3%苦参碱水剂（AS） 1 200倍液防治效果最差, 药后7 d防治效果为62.75%。供试生物源药剂对草莓生长安全, 无药害发生。在草莓生产中, 可优先选择1.8%阿维菌素ME 1 400倍液、2.5%鱼藤酮EC 400倍液分别对叶螨、蚜虫进行防治。 |

| Leaf mite and aphid are important pests in strawberry production. In order to reduce the use of chemical pesticides and improve the control effect, several bio-pesticides were selected to compare the control effect on mites and aphids. The results showed that the 1 400 times solution of abamectin 1.8% ME had the best control effect on the mites, with the efficacy of 81.15% seven days after application, which was significantly higher than those of other pesticides. The control efficacy of rotenone 2.5% EC 600 times solution was the worst, which was only 46.87% seven days after application. Rotenone 2.5% EC 400 times solution had the best control effect against the aphids, with the efficacy of 85.08% seven days after application, and matrine 1.3% AS 1 200 times solution showed the lowest control effect, which was 62.75% seven days after application. All of the tested bio-pesticides were safe to strawberry and no damage was observed. In strawberry production, abamectin 1.8% ME 1 400 times solution and rotenone 2.5% EC 400 times solution are recommend as a priority for the control of mites and aphids, respectively. |
