摘　　要：梨瘿蚊在河南1年发生3～4代。翌年3月下旬越冬代成虫开始出现，4—6月为发生为害盛期。平均枝梢被害率，第1代为22．10％，第2代为58．91％。在做好树上化学防治的同时，应注意加强地面防治。龟纹瓢虫、草蛉、小花蝽等对第3代梨瘿蚊具有较好的控制效果，应注意保护和利用。Dasineura pyri （Bouche） reproduces three to four generations every year in Henan. The adults of over- wintering generation began to appear in late March the following year, and the period for occurrence and damage was from April to June. The average rate of damage to the shoot was 22. 10% for the first generation, and 58.91% for the second generation. The control of D. pyri should be taken both in the tree and on the ground at the same time. Propylaea japonica, lacewings and Orius minutus had better control effects on the 3rd generation, which should be protected and utilized.
