摘　　要：[目的]确立安庆市单季中稻主要害虫的防治模式,以达到最佳经济效益。[方法]通过不同防治模式的对比试验,分析不同单剂和混剂对单季中稻主要害虫(稻纵卷叶螟、二化螟、稻飞虱)的防治效果,按节约成本、增加收入的原则,评价最佳防治模式。[结果]2种防治模式的对比试验表明,在水稻生长分蘖期施用5%锐劲特750 ml/hm2,穗期施用40%毒死蜱1200 ml/hm2+25%扑虱灵1200 g/hm2的防治模式可全程控制单季中稻田主要害虫的为害,较常规防治方法每公顷可提高经济效益千元以上,减少成本176元,同时减少了农药对环境的污染,保护了稻田的生态平衡。[结论]该防治模式防治效果显著,并达到最佳经济效益,是安庆市单季中稻主要害虫的最佳防治模式。[Objective] The objective of the study was to establish the control model of major pests in single cropping medium rice so as to achieve the optimum economic benefit.[Method]Through the comparative experiment on different control modes,the control effects of single and compound pesticides on the major pests（Cnaphalocrocis medinalis,Chilo suppressalis,Planthopper species） in single cropping medium rice were analyzed and optimum control model according to the principles of saving cost and increasing revenue was evaluated.[Result] The comparative experiment on 2 control modes showed that the control model of using 5% Regent at 750 ml/hm^2 at rice tiller stage,40% Chlorpyrifos at 1 200 ml/hm^2 and 25% Buprofezin at 1 200 g/hm^2 at rice booting stage could control the major pests at all the rice stages in single cropping medium rice.Compared with traditional controls,the control mode could increase the economic efficiency at more than 1 000 RMB and save 176 RMB cost per acre and also lessen the pollution of pesticides on environment and protect the ecological balance.[Conclusion] The control model,which could achieve the optimum economic benefit and have best control effects,was effective to the major pests in single cropping medium rice.
