摘要
中黑盲蝽已经成为我国农业生产的重要害虫,本文应用生态位和地统计学的理论和方法研究了紫花苜蓿田中黑盲蝽、东亚小花蝽、龟纹瓢虫和三突花蛛的空间相关性和空间分布。结果显示,中黑盲蝽与东亚小花蝽和龟纹瓢虫的生态位重叠度较高,与三突花蛛的生态位重叠度较低。地统计学分析显示,在紫花苜蓿田中,中黑盲蝽、东亚小花蝽、龟纹瓢虫都呈聚集分布,其空间相关范围分别为11.59、31.32和5.29 m。
Adelphocoris suturalis has been one of the most serious pests in the agricultural production. The spatial correlation and structure of A. suturalis , Orius sauteri , Propylaea japonica and Misumenops tricuspidams in alfalfa （Medicago sativa） field were studied with ecological niche and geostatistics methods. The re- suits showed that the ecological niche of A. suturalis highly overlapped withO. sauteri and P. japonica, while lowly overlapped with M. tricuspidatus. The geostatistics analysis indicated that the spatial patterns of A. suturalis, O. sauteri and P. japonica were all aggregate type with the range of 11.59 m, 31.32 m and 5.29 m.
