最近几十年来昆虫毒理学有一定的进展,特别是应用示踪原子方法后,发展比较迅速。但研究工作大部分局限于实验室内,在田间所进行的试验一般只限于药效的测定,没有从药剂应用的实际情况全面来研究问题。在实验室内进行的工作,关于杀虫作用机制、致死量中率的测定等做得特别多,这些资料当然有一定的价值,但拿它来说明田间农药使用的实际效果,总结提高为理论,则具有很大的局限性。因为昆虫毒理学是合理生产和使用杀虫药剂的理论基础,它应该是杀虫剂在生产实践和田间使用的基础上所发展形成的学科,但室内毒理 In recent decades, insect toxicology has made some progress, especially after the application of tracer atom method, the development is relatively rapid. However, most of the research work is confined to the laboratory. The tests conducted in the field are generally limited to the determination of the efficacy, and the problems are not comprehensively studied from the actual situation of the application of the medicament. In the laboratory work done on the insecticidal mechanism, the determination of the proportion of lethal dose has done so much, of course, these data have some value, but to illustrate the actual effect of pesticide use in the field, summed up as theory , It has great limitations. Because insect toxicology is the rationale for the rational production and use of insecticides, it should be a discipline developed by pesticides based on production practices and field use, but indoor toxicology
