Abstract: The field trials on the sustainable management of the whitebacked planthopper, Sogatella furcifera through planting resistant cultivars and reducing insecticide use were conducted by investigating number of insect pests and spiders, measuring rice yield and 1000-grain weight and comparison of net income from rice production in Fuyang, Zhejiang and Xiu- shan, Chongqing. Insecticide treatments were sprayed insecticides twice and farmer-self management,and not spraying insecticides severed as control. Results indicated that number of adults and nymphs of S. furcifera on the resistant cultivar Jiahua 1 under all insecticide treatments was at 0 9-3 3 insects/plant, and 826 7 times lower than that on the susceptible cultivar Zhongxiang 1 without insecticide treatment. Number of spiders in the plots without insecticide treatment was 2 8-5 5 and 1 6-4 1 times more than ones with insecticides sprayed twice and farmer-self management. Under the same insecticide treatment, the quantity and percentage of yield loss on resistant or tolerant cultivars were obviously lower than those on susceptible ones. Planting resistant cultivar Jiahua 1 could increase net income up to 1 13%-15 91% of without insecticide use. It could be concluded that S. furcifera could be efficiently suppressed by planting resistant or tolerant cultivars, reducing insecticide use to 2 times and up to no insecticides, and maximizing the controlling effect of spiders to insect pests so as to achieve the similar net income with ordinary use of insecticides at 4-5 times per rice season and even higher.

摘要： 采用田间虫情和天敌数量调查、水稻产量与千粒重测定和水稻生产实际收益比较的方法，在浙江富阳和重庆秀山两地进行了种植抗虫品种和减量使用杀虫剂的白背飞虱可持续治理技术的田间试验。设使用杀虫剂2次和农户管理(使用杀虫剂4~5次)两个处理，无杀虫剂作为对照。试验结果表明，抗虫品种嘉花1号在各种杀虫剂处理中，白背飞虱成、若虫数量最低(0.9～3.3只/株)，是感虫品种中香1号无杀虫剂处理的0.12%。无杀虫剂处理的蜘蛛数量分别是农户管理和杀虫剂2次处理的2.8～5.5倍和1.6～4.1倍。在同样的杀虫剂处理条件下，抗虫和耐虫品种的稻谷损失量和损失率较感虫品种明显地低。水稻生产的实际收益比较显示，无杀虫剂处理，种植嘉花1号可以增收1.13%～15.91%。因此，稻农种植抗虫或耐虫品种，减量使用杀虫剂至2次或不使用杀虫剂，充分利用蜘蛛等天敌的控制作用，完全能够有效地抑制白背飞虱种群的发生和发展，获得与常规杀虫剂用量 (4~5次)相仿或更高的收益。
