| 摘 要： | 异色瓢虫显现变种在野外对杨树上两种主要蚜虫白杨毛蚜和白毛蚜有较好的控制作用。在实验室条件下,测定了异色瓢虫显现变种对两种蚜虫的选择效应。白杨毛蚜和白毛蚜种群数量同步增加时,EG-S值和EI值变化是从1到0,EI值是在0到-1范围内依次减少,且数值变化较少,表明异色瓢虫显现变种喜好捕食白毛蚜略高于白杨毛蚜;白杨毛蚜数量不变,白毛蚜数量增加时,EG-S值和EI值是从1到0,EI值在0到-1范围内依次减少,表明异色瓢虫显现变种明显喜好捕食白毛蚜;白毛蚜数量不变,白杨毛蚜数量增加时,EG-S值和EI值变化从＋1到∞,EI值在0到＋1范围内依次增加,表明异色瓢虫显现变种明显喜好捕食白杨毛蚜。 |

| Abstract: | Harmonia axyridis ab.conspicua was one of important predators of Chaitophorus populeti and C.populialbae.Selection effect of Harmonia axyridis ab.conspicua to Chaitophorus populeti and C.populialbae was investigated in lab.The result showed that change of EG-S value and EI value was from 1 to 0,EI value was in order to decrease between 0 and-1 during synchronic augmentation of Chaitophorus populeti and C.populialbae population.This result indicated that Harmonia axyridis ab.conspicua was more likely to prey... |
