众所周知,防治农林作物害虫的杀虫剂,主要是通过胃毒作用、触杀作用、内吸作用、熏蒸作用等方式毒杀害虫的。随着人们物质生活水平的不断提高,人们对赖以生存的环境质量的要求也越来越高,对新开发的农药必须首先考虑的是与环境友好、相容,其次是杀虫的生物活性,即要求符合安全性高、选择性强、无公害、低残留、生物活性高,使用方便且成本低。近几十年来,各国科学家
It is well-known that pesticides for controlling pests of agricultural and forestry crops are mainly used to kill pests through stomach poisoning, contact killing, internal absorption and fumigation. With the continuous improvement of people’s living standards, people’s requirements for the quality of the environment they depend on are also getting higher and higher. Newly-developed pesticides must first of all be considered environmentally friendly and compatible, followed by insecticidal biological activity , Which requires compliance with high safety, selectivity, pollution-free, low residue, high biological activity, easy to use and low cost. In recent decades, scientists from various countries
