昆虫在自然界中通过物质交换和能量代谢的方式与环境紧密联系,并在长期进化过程中形成了对环境的适应性。不同种类的昆虫对环境条件的要求及其适应的程度、范围有所不同,因此它的生长发育等一系列生命活动均受环境条件的影响。环境条件适宜,对昆虫的发生发展有利。昆虫的生命活动也不断影响栖息的环境,因此,昆虫和它所生活的环境是一个复杂的体系。在这个复杂的体系中,各种环境条件彼此相互联系而又同时综合作用于昆虫。我们防治害虫利用益虫既要研 Insects are closely linked with the environment through the exchange of matter and energy metabolism in nature, and form the environmental adaptability in the long-term evolutionary process. Different types of insects on the environmental conditions and the extent of their adaptation requirements, the scope is different, so its growth and development and a series of life activities are subject to environmental conditions. Appropriate environmental conditions, the occurrence and development of insects beneficial. Insect life activities also continue to affect the habitat of the environment, therefore, insects and the environment in which it lives is a complex system. In this complex system, a variety of environmental conditions are interconnected with each other and simultaneously act on insects. It is necessary for us to prevent and control insect pests by using beneficial insects
