苹果对环境的适应性较强,从我国东部沿海平地到西部海拔几千米高原,在这广阔的不同生态条件下,都能生长结果。苹果上的害虫同样表现出对各种生态条件的适应能力,某些种类几乎在各个苹果栽培区内都有发生,特别是食心虫类为害损失最为严重。采用化学农药防治,虽然可以减轻损失;但长期、广泛使用,杀伤了大量天敌,使苹果园中原来不重要的叶螨类猖獗起来。继之以有机磷等杀螨剂防治,不久,叶螨中的某些种类形成了抗性种群。
Apple has a strong adaptability to the environment. From the coastal plain in the east of China to the altitude of several kilometers in the western part of the plateau, the apple can grow in this vast and diverse ecological environment. Pests on apples also showed their ability to adapt to various ecological conditions. Some species occurred in almost all apple-growing areas. In particular, the damage caused by gummy insects was the most serious. The use of chemical pesticide control, although it can reduce the loss; but long-term, widespread use, killing a large number of natural enemies, so that the original apple orchard spider mite rampant rampant. Followed by organic phosphorus and other acaricide control, and soon, some species of spider mites formed resistant populations.
