抗药性是一种进化现象。本文从遗传角度对抗性进化的本质进行探讨,并分析抗性基因突变的主要类型,以期对害虫抗药性的进化和防治的有更好的理解。一害虫抗药性进化的遗传本质1.遗传变异是害虫抗药性进化的基础害虫对杀虫剂的抗性是生物进化的一个典型例子,可以从生物进化角度对害虫抗药性进化进行分析。生物进化的基础是生物遗传结构的不稳定性和变异的普遍性,这种变异的普遍性结合环境的复杂性造成了生物的多样性,给生物进化带来可能。
Drug resistance is an evolutionary phenomenon. This article discusses the nature of resistance evolution from the genetic point of view, and analyzes the main types of resistance gene mutations in order to better understand the evolution and control of pest resistance. The genetic nature of a pest resistance evolution 1. Genetic variation is the basis for pest resistance evolution Pest resistance to insecticides is a typical example of biological evolution, from the perspective of biological evolution of pest resistance evolution analysis. The basis of biological evolution is the instability of biological genetic structure and the universality of mutation. The universality of such variation causes the biological diversity in combination with the complexity of environment, and brings the possibility of biological evolution.
