摘  要：
通过田间调查,分析比较了有机耕种稻田和常规耕种稻田害虫和天敌的发生动态.结果表明,在有机稻田主要害虫的发生动态较对照缓和,次要害虫发生种类有所差异,而蜘蛛、捕食性昆虫和寄生蜂等稻田主要天敌数量上明显高于对照,表明停用化学合成物质后天敌的控害作用得到了恢复和明显的加强.

摘  要：
Through a whole year field investigation,this paper analyzed the population dynamics of pests and their enemies in organic and normally cultivated rice fields.The results indicated that the population of main pests varied more lightly in organic than in normally cultivated rice field,while subordinated pest species had little difference between these two fields.The individuals of enemies were more in organic than in normally cultivated rice field.It is suggested that the pest-control effect of enemies could be restored and became stronger when no chemical pesticides were applied.
