摘要
为给桃蚜生态防治提供参考,作者对生草处理区和清耕处理区的桃蚜及其天敌发生情况进行监测。结果表明,生草处理区桃蚜发生数量显著低于清耕处理区,且发生平缓,高峰期推迟;桃蚜天敌的发生数量增加,这对控制早春桃蚜虫口密度和全年发生程度作用显著。
In order to provide reference for ecological control of Myzus persicae,the occurrence of Myzus persicae and its natural enemies in grass growing treatment area and clear tillage treatment area were monitored.The results showed that the number of Myzus persicae in grass treatment area was significantly lower than that in clean tillage treatment area,and the occurrence was gentle,and the peak period was delayed;The number of their natural enemies increased,which played a significant role in controlling the population density of Myzus persicae in early spring and the occurrence degree in the whole year.
