对严重危害豇豆和菜豆的 2种主要潜叶蝇及其天敌在时间和空间维度上的生态位重叠与生态位宽度作了定量估计 结果表明 ,豇豆田寄生蜂对美洲斑潜蝇有较强的控制效果 ,几种天敌对豌豆植潜蝇控制效果不明显 菜豆田七星瓢虫和寄生蜂对蜿豆植潜蝇有较强的控制作用 ,龟纹瓢虫、异色瓢虫、蜘蛛、寄生蜂对美洲斑潜蝇也有较好的控制效果
The ecological niche overlap and niche breadth of two main leaf miner and its natural enemies that seriously endangered the cowpea and kidney bean were quantitatively estimated. The results showed that the cowpea parasitoids had stronger Control effect, the effect of several natural enemies on the control of pea moths was not obvious. The ladybugs and the parasitic wasps had a strong control effect on the moths, the ladybugs, the ladybugs, the spiders, the parasitic wasps There is also a good control effect on the leafminers
