苹果小卷叶蛾(Adoxophyes oranaFischer von R(?)slerstamm)是我国北方苹果产区一种重要害虫,除为害苹果外,还为害桃、梨、李、杏、山楂等果树的叶片和果面。对于苹果小卷叶蛾等卷叶蛾类害虫的防治,以往偏重于化学防治,常用药剂是有机磷或有机氯等广谱杀虫剂,取得了较好的防治效果,但这类药剂对苹果园中另一类主要害虫——叶螨效果很差,或因多年使用而产生抗性种群,防治效果减退。相反,对叶螨的多种捕食性天敌杀伤作用很大,如使用不当往往导致叶螨猖獗为害。所以,提高防治卷叶蛾的水平,是苹果害虫综合防治中急待研究解决的问题之一。
Adoxophyes oranaFischer von R (?) Slerstamm is an important pest in the apple producing area in the north of China. In addition to apples, it also damages the leaves and fruit surfaces of fruit trees such as peach, pear, plum, apricot and hawthorn. In the past, the prevention and treatment of leaf roller moth pests such as apple leaf roller had been focused on chemical control. The commonly used pesticides were broad-spectrum insecticides such as organophosphorus or organochlorine, and the better control effect was obtained. However, The main pest - spider mite is very poor, or due to years of use and produce resistant populations, prevention and control effect diminished. In contrast, spider mites on a variety of predatory natural enemies killing a great role, such as improper use often lead to spider mite rampant damage. Therefore, to improve the level of prevention and control of leaf roller moth, apple pest is one of the problems to be solved in the comprehensive prevention and treatment.
