化学防治是解决害虫问题最为有效的手段之一,三十年来曾对杀虫药剂和毒理学做了不少的科学研究。据统计,《昆虫学报》发表的有关论文在第一个十年中占总篇数的9％,反映我国对害虫的化学防治在早期已有一定的基础。然而,最早试验用昆虫病原防治害虫开始于五十年代中期,对于昆虫病毒的研究开始于六十年代,所以昆虫病理学在我国的开展较晚。这两门能密切结合生产实践的昆虫学分支学科的内容和在我国发展的过程不同,宜加以分述。
Chemical control is one of the most effective ways to solve pest problems. In the past 30 years, many scientific researches have been done on pesticides and toxicology. According to statistics, the related papers published in the Journal of Entomology account for 9% of the total number of articles in the first decade, which shows that chemical control of pests in our country has already had some foundation in the early stage. However, the earliest experimental pest control of insect pathogens began in the mid-1950s, and the research on insect viruses began in the 1960s. So, the insect pathology is carried out later in our country. The two branches of entomology, which closely integrate production practices, differ from the course of development in our country and should be divided.
