摘　　要：本文研究了由新的抗虫材料‘中9A-07/WH1462’与控氮、晒田和天敌保护等措施有机结合的环境友好集成技术体系对稻飞虱的控制效果。结果表明,该技术体系在未施用化学农药的情况下,使稻飞虱等害虫种群数量得到有效控制,较好地保护了天敌,使稻田节肢动物群落结构得到一定优化。集成技术稻田的害虫所占比例比对照田降低了57.6%,其天敌所占比例比对照田增加了19.6%,同时集成技术稻田的水稻产量比对照田增加了10.9%。The effects of the environment friendly integrated technology, containing the new insectresistant materials ‘zhong 9A07/WH1462’, nitrogen control measures, sunning the fields, protection of natural enemies, on rice planthopper control were studied. The results showed that these measures could effectively control the quantity of rice planthoppers and other pests, protect natural enemies, and optimize community structure of arthropods without application of chemical pesticides. The proportion of pests in fields managed by integrated technology was 57.6% lower than that in the control field; the proportion of natural enemies in fields managed by integrated technology was 19.6% higher than that in control field. The yield of rice in fields managed by integrated technology was 10.9% higher than that in the control field.
