| 中文摘要: |
| 棉田中种植玉米诱集带不仅可以增加棉田捕食性天敌的数量,而且还有诱集天敌的作用。在棉花生长期间,瓢虫、蜘蛛和草蛉三者的总数均为玉米诱集带>处理棉田>对照棉田。其中瓢虫占捕食性天敌的89.89%,草蛉占2.24%,蜘蛛占7.86%。棉田天敌优势种群是十一星瓢虫,它占瓢虫总数的82.66%,而且处理棉田十一星瓢虫的数量明显高于对照棉田,是对照棉田的1.8倍。 |
| 英文摘要: |
| Planting trap corn could not only increase the quantity of native predators in the cotton fields, but also concentrate them on the trap corn. The distribution of ladybirds, green lacewings and spiders during cotton growth period was: the trap corn>the treatment cotton field>the contrast cotton field. There were 89.89% ladybirds, 2.24% green lacewings and 7.86% spiders in the native predators. Coccinella undecimpunctata Linnaeus was the dominant species among them in the cotton fields, whose rate being 82.66%. Its quantity in the treatment cotton field was 1.8 times compared to that in the contrast cotton field. |
