摘要: 苜蓿是河西干旱半干旱生态脆弱区的重要农作物。本研究采用生态学和地统计学方法系统研究了河西地区苜蓿田节肢动物群落组成结构及主要害虫蚜虫与优势捕食性天敌的时空格局。群落调查中,共采集到节肢动物60641头,分属2纲9目33科67种,蚜虫为苜蓿田优势害虫,瓢虫为优势捕食性天敌。时空格局分析表明,苜蓿田蚜虫与龟纹瓢虫关系最为密切,在田间呈现明显的时间跟随效应和空间跟随效应。苜蓿具有作为河西地区重要功能植物进行天敌保育及害虫生态调控的应用潜力。

Abstract: Alfalfa is an important crop in the arid and semi-arid ecologically fragile areas of Hexi. In this study, the composition structure of arthropod community and the spatio-temporal pattern of main pest aphids and dominant predatory natural enemies of alfalfa field in Hexi region were systematically studied by means of ecology and geostatistics. In the community investigation, a total of 60641 individuals were collected, belonging to 2 classes, 9 orders, 33 families and 67 species. Aphids were the dominant pests and ladybugs were dominant predatory natural enemies of alfalfa field. The analysis of spatio-temporal pattern showed that aphids were most closely related to Propylaea japonica, showing obvious time and space-following effect in the field. Alfalfa has the application potential of natural enemy conservation and ecological control of insect pests as an important functional plant in Hexi region.

Key words: alfalfa, arthropods community, aphids, Propylaea japonica, spatio-temporal pattern
