生态防治 Ecological prevention and control 　　

　　生物防治是指根据有害生物种群分类、生活习性、及当地的环境、气候、温度与害虫的活动频率等，结合相关技术规范要求，采取各种措施或开展各项活动，创造不利于害虫滋生之条件。而增加对害虫天敌的种类或数量，来打破自然界的相对平衡，使之不利于害虫种群的增长，从而减少和防止它们的为害。其特点是对人、畜安全，不污染环境，有较长的持续抑制作用。 　　

　　Ecological prevention and control means to take various measures and carry out a series of activities to create conditions that are unfavorable to growth of pests according to relevant technological regulations based on classification of species of pests, their biological habits, local environment, climate, temperature and frequency of their activities. We can break the balance of nature by increasing the category and quantity of pests' natural enemy so as to limit their growth and thus prevent the harm. It is safe to human and livestock, environment-friendly and of long-lasting effect on pests.

　　4、对发现害虫严重为害时应及时反馈害虫防治单位进行处理，切勿忽略或自行处理。 生态创建不利于害虫的蔓延、孳生、栖息场所，对预防害虫侵害起到事半功倍的效应。 　　

　　When serious harm is discovered, pest prevention and control institution should be called promptly to deal with it. Never ignore it or handle it by yourself. Ecological prevention and control creates conditions unfavorable to proliferation, propagation and habitation for pests, and thus can achieve outstanding results with minimum effort
