| 摘 要： | 本研究了BT基因棉与常规棉主要害虫及天敌的生态位。结果表明：主要害虫及天敌的种类一致,但棉铃虫幼虫的数量差异显;33B棉田各昆虫种群的生态位宽度指数偏高;棉铃虫、棉蚜对主要天敌的生态位重叠指数偏高。应用生态位概念分析了造成区别的原因。

| Abstract: | A research result on the niches of major pests and their natural enemies between BT cotton and common cotton showed that major pests and their natural enemies were similar, but the number of cotton bollworm on BT cotton was lower than that on common cotton. The niche breadth index of insect population on BT cotton was higher than that on common cotton. The niche overlap index of cotton bollworm and Aphis gossypii Glover to four natural enemies on BT cotton was higher than that on common cotton. The reason was analysed by the theory of niches. |
