研究了强化栽培单季稻稻田生态系统中水稻主要病虫的发生规律及使用农药防治靶标病虫时对非靶标病虫的影响.结果表明,强化栽培方式下褐飞虱种群数最较常规栽培方式增加了21.47%,白背飞虱增加了27.19%,稻纵卷叶螟增加了57.95%,二化螟增加了200.0%,纹枯病病情指数增加了29.10%.防治病虫靶标对非靶标病虫种群发展的影响以稻飞虱最为突出,用杀虫双、茚虫威、井冈霉素和苯甲·丙环唑等药剂防治螟虫,稻纵卷叶螟和纹枯病等靶标病虫时,均会刺激褐飞虱和白背飞虱种群数量增殖,其增殖幅度较常规栽培方式提高了26%～60%.

The occurrence of the key diseases and insect pests in single crop rice system under intensified cultivation has been investigated. Effects of pesticides on non-target diseases and insect pests when the pesticides were used to control targets in rice field was also studied. The results showed that the populations of brown planthopper (Nilaparvata lugens),whitebacked planthopper (Sogatella furcifera),rice leaf folder (Cnaphalocrocis medinalis) and striped stem borer (Chilo suppressalis) under intensified rice cultivation system were increased by 21.7%, 27.19%,57.95% and 200.0%,respectively,while the rice sheath blight (Rhizoctonia solani) disease index was increased by 29.10% compared with that under conventional rice cultivation system. Non-target diseases and insect pests were obviously affected by spraying pesticides such as dimehypo, indoxacarb, validamycin, difenoconazole and propiconazole to control striped stem borer, rice leaf folder and rice sheath blight, and the populations of brown planthopper and whitebacked planthopper were all stimulated and proliferated with the increase of 26%-60% than that in conventional rice cultivation system
