昆虫抗药性是化学防治中的一个重要问题。远在60年代初期,我国很多科研部门,对农、林、卫生等重要害虫,进行了大量抗性研究,个别单位对益虫的抗性亦进行了一些探索,取得了不少成效。但在十年动乱中,绝大多数科研部门停止了这方面的研究,以致几种重要害虫抗性的发展情况不很清楚,加以近几年来,不少农药的质量下降,有些地区的使用情况亦比较混乱,目前不少农药对害虫的防治效果减退,是质量问题,还是抗性问题?应该弄清楚。 近20年来,国外在抗性调查与抗性机理研究有很大的进展,世界卫生组织与粮农组织,对不少重要害虫提出了统一规定的调查方法;不少专业研究单位对重要害虫的生理、 生化、遗传等抗性机理方面亦发表了不少论著。 为了赶上形势发展,本刊从本期起开辟专题讲座专栏,并约请从事这方面研究的专业人员,结合国内外情况,较有系统的陆续刊登不同类型昆虫抗性的培育与测定方法、抗性生化机理、抗性遗传机理、防治抗性害虫策略等文章,以供读者参考。
Insect resistance is an important issue in chemical control. As far back as the early 1960s, many scientific research departments in our country conducted a great deal of resistance research on important pests such as agriculture, forestry and public health, and some individual units also made some explorations on the resistance to beneficial insects. Much has been achieved. However, during the ten years of turmoil, the vast majority of scientific research departments stopped their research in this area. As a result, the development of resistance to several important pests was not well understood. In recent years, the quality of many pesticides has dropped. In some areas, Also more chaotic, at present, many pesticides on the prevention and control of pests diminished, is the quality problem, or resistance? It should be clear. In the recent 20 years, great progress has been made in the research on resistance investigation and resistance mechanism in foreign countries. WHO and FAO have put forward unified survey methods for many important pests. Many professional research institutes have studied the physiology of important pests , Biochemistry, genetic resistance mechanism also published a lot of work. In order to catch up with the development of the situation, this issue has opened a special lecture column from this issue and invited professionals engaged in research in this area. Based on the domestic and international situations, we systematically published different types of insect resistance cultivation and determination methods Sexual biochemical mechanism, genetic mechanism of resistance, pest control strategy and other articles, for readers reference.
