我們认为昆虫毒理学的研究对象应来自田間,来自生产实践。因此,提出田間毒理的发展方向問題,进行研討。 田間毒理的目的和任务 近几年来昆虫毒理学有一定的发展,特别是应用示踪原子方法及示踪原子和彩譜相結合的方法进行研究后,加快了发展的速度。但是过去大部分工作局限于室內,偏重于杀虫作用机制,药剂在虫体內的代謝及致死量中率(LD_50)測定的研究,而在田間进行的試驗一般只 We think that the object of insect toxicology research should come from the field, from the production practice. Therefore, put forward the direction of the development of field toxicology problems, to discuss. Aims and tasks of field toxicologyIn recent years, insect toxicology has some development, especially the application of tracer atom method and tracer atom and the method of combining color spectrum to speed up the development of the speed. However, in the past most of the work was limited to indoors, focusing on insecticidal mechanism of action, drug metabolism in the body and mortality rate (LD_50) determination of the study, and in the field trials generally
