| 中文摘要: |
| 以Bt棉和常规棉为对照，研究了转cry1Ac+cry2Ab棉对棉田节肢动物群落的影响。研究结果表明，转cry1Ac+cry2Ab棉田、转cry1Ac棉田和常规棉田节肢动物群落、害虫亚群落和天敌亚群落的结构与组成无明显差异；转cry1Ac+cry2Ab棉田刺吸类害虫、蛀食类害虫和食叶类害的数量均低于转cry1Ac棉田和常规棉田；转cry1Ac+cry2Ab棉田蜘蛛类、瓢虫类和捕食类天敌的数量均低于转cry1Ac棉田和常规棉田；转cry1Ac+cry2Ab棉田节肢动物群落、害虫亚群落和天敌亚群落的多样性指数与转cry1Ac棉田和常规棉田相比均无明显差异，说明转cry1Ac+cry2Ab棉田节肢动物群落、害虫亚群落和天敌亚群落的稳定性和转cry1Ac棉和常规棉相比均无明显差异。 |
| 英文摘要: |
| The effects of transgenic cotton with cry1Ac+cry2Ab on arthropod communities were studied, with transgenic cotton with cry1Ac and conventional cotton as the controls. The results showed that there were no significant differences in the structure and composition of arthropod community, pest sub community and natural enemy communities among the three cotton fields. The numbers of piercing sucking pests, trunk boring pests, defoliating insects and spiders, ladybirds and predatory natural enemies were decreased in transgenic cotton with cry1Ac+cry2Ab fields than in transgenic cotton with cry1Ac and conventional cotton fields. The diversity indexes of arthropod community, pest sub community and natural enemy communities showed no significant difference among the three cotton fields, indicating that there was no significant difference in the community stability of arthropod community, pest sub community and natural enemy communities among different cotton fields. |
