| 摘 要： | 大草蛉(Chrysopa septempunctata)是华北农区的主要天敌昆虫,研究了作物主要生长季节大草蛉的分布动态及其对栖息地的选择取向,结果表明,(1)大草蛉对栖息生境有较强的选择性,明显趋向于田间杂草地生境;(2)大草蛉在田间草地带上的栖息较为稳定,且受田间草地带宽度的直接影响,宽度1m左右的草地带有更高的大草蛉密度;(3)林带对大草蛉分布显示出积极作用,其效应范围因林带结构不同表现各异;(4)作物生长后期林带逐渐成为大草蛉栖息的重要场所。 |
| 关 键 词： | 大草蛉 栖息地选择 草地 林带 |

| Abstract: | The study is on the distribution dynamics and habitat selection of C.septempunctata which is the main predator in crop fields in North China.The result shows that:firstly,C.septempunctata is inclined to the weed habitats;secondly,the distribution of C.septempunctata in the weed is stable,and it is affected directly by the width of weed,with 1m width of weed having larger density of C.septempunctata;thirdly,the forest belt plays a positive role in the distribution of C.septempunctata,and the function extents of forest belt is different along with the structure of forest belt;fourthly,forest belt becomes an important habitat in the later period of crop growth. |
