系统比较了不防除杂草、不整枝打杈、喷施缩节胺、设置黄板、棉田种植诱集作物及邻作诱集作物等不同生态带棉田与其对照棉田的棉蚜种群消长动态。结果表明,棉蚜发生期,棉田临近设置黄板、喷施缩节胺、及时防除杂草、条带种植玉米、绿豆和向日葵诱集带、整枝打杈均对棉蚜有良好的控制作用。玉米、蔬菜和果树与棉花邻作对棉田苗蚜发生有较好的控制作用,但对后期棉田棉蚜未见抑制作用;后期应根据预测预报进行化学防治。
The population dynamics of cotton aphid populations in different ecotypes and adjacent cotton fields were compared systematically. The results showed that the population dynamics of cotton aphids was not controlled by weed control, pruning, pruning, yellowing, cotton planting and adjacent crops. The results showed that cotton aphid had a good control effect on cotton aphid when the cotton aphid occurred, the yellow plate was set near the cotton field, the amylin was sprayed, the weeds were controlled and the corn, mung bean and sunflower traps were planted in the strip. Maize, vegetables, fruit trees and cotton neighbors had better control effect on seedling aphid in cotton field, but had no inhibitory effect on cotton aphid in cotton field in late stage. Chemical control should be carried out in the later stage according to forecasting and forecasting.
