| 摘 要： | 对武汉地区春播和夏播豇豆田生态系统中主要害虫、天敌的种类及空间、时间生态位进行了调查研究。结果表明,春播和夏播豇豆中,瓢虫、蜘蛛和捕食蝽同主要害虫的生态位重叠较大,跟随作用强,具保护利用价值;害虫生态位宽度以蚜虫LipaahiserysimiKaltenbach、蓟马ThripspalmiKarny、豆野螟MarucatestulalisGeyer较宽,天敌生态位春播田中瓢虫较宽,夏播田中蜘蛛较宽。

| Abstract: | The species of important pests and naturl enemies and their temporal and spatial niches in eowpea field in Wuhan were studied. The result showed that there were obvious niche overlaps among ladybgs, spiders, preying true bugs. The natural enemies were worth of protecting because they bad strong pursuing effect to the main pests. The niche width of Lipaahis erysimi Kahenbach, Thrips palmi Karuy and Maruca testulalis Geyer were wider among pests. Among natural enemies, the niche width of ladybugs were wider in spring sowing field and that of spiders were wider in summr sowing field. |
