潜叶蛾(Phyllocnistis citrella Stainton)是我省柑桔重要害虫之一。主要为害夏梢和秋梢嫩叶。幼虫潜入表皮下取食叶肉。卵产在新梢嫩叶上,孵化的幼虫即潜入叶内为害,是较难防治的害虫。近几年我们使用拟除虫菊酯在夏梢与秋梢放梢5—9天,大部分新梢长3—4厘米时喷布叶面,对杀伤幼虫和保梢护叶均获得满意的效果。 1984年我们使用日本住友化学工业株式会社生产的速灭杀丁乳油防治柑桔潜叶蛾,也获得良好效果,现将试验结果报导如下: Leaf moth (Phyllocnistis citrella Stainton) is one of the important citrus pests in our province. The main damage summer tip and autumn tip young leaves. The larvae sneak into the epidermis to eat the mesophyll. Eggs on the tender tip of young shoots, hatching larvae that sneak into the leaves, is more difficult to control pests. In recent years, we use pyrethroids in the summer shoots and autumn shoots shoot 5-9 days, most of the shoots 3-4 cm long when spraying the foliage, the killing of larvae and protect the leaves of leaves are to obtain satisfactory results. In 1984, Sumitomo Chemical Co., Ltd., Japan Sumitomo Chemical Co., Ltd. production of metronidazole butter cream control citrus leaf moth, also obtained good results, the test results are reported as follows:
