| 摘 要： | 研究了7—8月份夏大豆田主要食叶性害虫及其天敌的生态位宽度和生态位重叠度。分析了各昆虫种间的竞争动态，害虫与其天敌在时间上的同步性和空间上的同域性均较强，为保护利用自然天敌控制夏大豆害虫提供了科学依据。

| Abstract: | The main leaf-eating pests in soybean fields in summer from july to August and the breadth and overlap of the niches of their natural enemies were studied,with the analyzing for the competition among each species of insects.The results showed that the synchronization of time and the same-region of space between the pests and their natural enemies are both stronger,which provided a scientific foundation for protecting and using natural enemies to control the pests in soybean fields in summer. |
