| 摘 要： | 褐稻虱(Nilaparvuta lugens)是我国水稻的主要害虫。以往的粳稻品种,感褐稻虱;近几年来一系列抗褐稻虱品种如秀水620、秀水664已经育成,1990年已种植150万亩。种植抗性品种可少用或不用杀虫剂,能大量保存天敌,抗性品种与天敌的协同作用,对控制褐稻虱种群,改善防治策略,具有现实意义。该文报道了田间和实验室观察调查多种天敌的数量和捕食或寄生效果,估计了在不同抗感品种上褐稻虱种群趋势指数1值,并分析了粳稻抗性品种与蜘蛛类抑制褐稻虱的协同作用。

| Abstract: | Since the resistant japonica rice varieties to brown planthopper(BPH) Nilaparvata lugens(Stål) were developed and commercially used in Zhejiang Province,a great number of natural enemies have been preserved.The importance of the coordinate effects of resistant rice varieties and natural enemies on BPH population were explored.The results were as follows:(1) The natural enemies complex,including Anagrus spp.,dryinids,entomogenous nematode Agamermis sp.,Elenchi-nus japonicus,etc.,caused 63%(1985) and 73%(1989) suppressions ofBPH population. |
