对稻飞虱及其节肢类捕食性天敌的空间、时间以及时间—空间生态位关系进行分析,从理论上说明了捕食性天敌对稻飞虱的控制作用。早稻群落中,食虫沟瘤蛛和水狼蛛是稻飞虱的主要捕食者,而且它们之间存在明显的竞争作用。晚稻群落中食虫沟瘤蛛对稻飞虱的捕食作用仍然占主导地位,但由于缺乏食物资源,各捕食性种类之间的竞争作用加剧。 The space, time and time-space niche relationships of planthoppers and their predatory predators were analyzed, and the controlling effects of predatory natural enemies on planthoppers were theoretically demonstrated. In the early rice community, the predatory insectivore and water wolf spider are the main predators of planthoppers, and there is a clear competitive effect between them. The predation of Botryosporidium furcifera on planthoppers in late-season rice communities still dominates, but the competition between predatory species is aggravated by the lack of food resources.
