| 摘 要： | 为探索扑利旺在柑橘红蜘蛛上的应用效果，开展了扑利旺防治柑橘红蜘蛛卵室内试验以及在不同虫口基数和不同温度条件下的田间试验。结果表明：扑利旺可明显抑制柑橘红蜘蛛卵的孵化，且孵化后幼螨存活率降低，并对幼螨、若螨和成螨均有较好的防治效果。生产使用中，在虫口基数低（2-3头/叶）或春季红蜘蛛发生期，推荐扑利旺200-300倍喷雾处理或扑利旺500倍+24%螺螨酯5000倍喷雾处理；而在虫口基数高（9-10头/叶）或秋季红蜘蛛繁殖高峰期，推荐扑利旺200-300倍+ 24%螺螨酯5000倍喷雾处理来控制柑橘红蜘蛛的危害。

Application Research of PREV-AMPREV-AM Against Panonychus citri McGregor |
| |
| Abstract: | The laboratory tests of PREV-AMPREV-AM against Panonychus citri McGregor, and the field trials under different initial population numbers and temperatures, were studied to explore the application effect of PREV-AMagainst Panonychus citri McGregor. The results showed that PREV-AM had a good control effect against the spawn, larva, nymph and mite. Spraying treatment of PREV-AM diluted for 200-300 times or PREV-AMdiluted for 500 times with 24% spirodiclofendiluted for 5000 times was recommended to use when the initial population number was low (2-3 each leave) or during the spring emergence period of Panonychus citri McGregor. However, when the initial population number was high (9-10 each leave) or during the autumn reproduction period, spraying treatment of PREV-AM diluted for 200-300 times with 24% spirodiclofen diluted for 5000 times was recommended to control the Panonychus citri McGregor. |
