| 摘 要： | 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。

| Abstract: | The role of predators in controlling rice planthopper was theoretically studied according to the analysis of their space, time, and time-space niches. Ummeliala insecticeps Boes. et Str. , and Pirata spp. were the key predators of rice planthopper, and competed with each other for preys in early rice community. For lack of rice planthopper and other preys, competition between these predators was intense,and their niches changed obviously,but Ummeliata insecticeps Bose. et Str. still played a key role in controlling rice planthopper in late rice community. |
