旋纹潜叶蛾又名苹果潜叶蛾。主要以幼虫潜食叶片为害,过去一般在防治其他害虫的同时即可兼治。最近几年尤其是93、94两年该虫大发生,成了苹果、桃树的主要害虫。旋纹潜叶蛾幼虫在叶内螺旋状潜食叶肉,使叶形成圆形或不规则形的褐色虫斑,叶斑内黑色虫粪形成轮纹状,为害严重时每叶有十几个虫斑,可引起落叶。旋纹潜叶蛾在唐山地区一般每年发生三代,我省中、南部地区可发生四代。由于其幼虫潜叶危害,农药不易触到虫体,防治效果不太理想。今年我们通过试验观察,发现旋纹潜叶蛾成虫的活动范围小,一 Curved leaf miner, also known as apple leaf miner. Mainly to larvae eaten fresh leaves, in the past generally in the control of other pests at the same time can be both. In recent years, especially 93,94 two years the worm occurred, became the main pests of apple and peach trees. Helical leafhopper larvae in the leaves of spiral-like potential food leaf mesophyll, the leaves form a round or irregular brown spots, leaf spot black pest formation wheel-shaped, serious damage when there are dozens of insects per leaf Spot, can cause deciduous. Spinosa leaf moth in Tangshan area generally occur three generations each year, in our province, southern region can occur four generations. Due to its larvae latent leaf damage, pesticides are not easy to touch the parasites, control effect is not ideal. This year we passed the experimental observation and found that the activity of the adults of the leaf-spotted moth was small,
