| 摘 要： | 为开展棉田害虫生态控制,于2004年5～8月系统调查了新疆阿克苏棉区捕食性天敌的种群数量消长动态。结果表明:该地区捕食性天敌种类多数量大,有7目15科28种以上,高峰期天敌虫量平均达到8.86头/株;无干扰情况下能建立稳定的自然种群,对棉田发生的害虫基本上可有效控制;不同天敌田间消长动态存在差异,瓢虫和草蛉为优势种类。 |

| Abstract: | In order to implement ecological pest control effectively, the population dynamics of predatory enemies of cotton field were investigated. The results showed that natural enemies not only had a large number of kinds, but also could establish rather stable population in field, which had an effective control on pests. There were 28 species of predators belong- ing to 15 families of 7 classes;during the peak period, the number of enemies could reach 8.86 per plant. Natural population dynamics from various types of enemies were different. Lady beetles and green lacewing were the dominant species of predatory entreties. |
| Keywords: | pest biocontrol predatory enemies population dynamics dominant species |
