摘　　要：蜕皮激素类似物美满(methoxyfenozide)对甜菜夜蛾(SpodopteraexiguaHubner)有突出的防治效果,田间使用24%美满悬浮剂3000倍、6000倍,药后1天、3天、7天防治效果分别达到93.42%,97.05%,98.39%和82.61%,88.87%,89.38%,与10%除尽(chlorfenapyr)1500倍相当。美满与乐斯本(chlorpyrifos)混配使用,也可以达到理想的防治效果。且能节约用药成本,在作物生长前期可适当使用。仿生的蜕皮激素类似物是当前无公害蔬菜生产中值得推荐的好农药。Field trial for effect of methoxyfenozide, a moetion hormone analon, on Spodoptera exigua was carried out in Zhejiang, China in 2002. The result shows that methoxyfenozide is very effective on larvae of the pest, with the efficacy of 93.42%, 97.05%, 98.39% at the concentration of 3 000 dilution for 24%SC at 1, 3, 7 DAT, and 82.61%, 88.87%, 89.38% at 6 000 dilution, respectively. The effect of methoxyfenozide on the pest is the same as chlorfenapyr at 1 500 dilution for 10%SC. When mixed with chlorpyrifos, methoxyfenozide controls the pest at lower concentration, making control cost less.Therefore, methoxyfenozide is recommended to be used in production of non-hazard vegetable.
