近代有机杀虫剂的问世,是人类同害虫斗争史上的一个里程碑。但由于不合理的使用和个别品种本质上存在的问题,导致害虫产生抗药性、环境污染、人畜中毒、破坏生态平衡等问题,从而引起了举世的关注。研究工作者们试图从各个途径来解决这些问题,如生物防治、农业技术防治、培育抗虫品种等。但目前在国内外较为广泛研究,并取得重大成果的是从天然产物中寻找生物活性物质,经分离、提纯,测定分子结构后,作为人工合成新农药品种的模板(如拟除虫菊酯、沙蚕毒的衍生物等),已成为当代杀虫剂的
The advent of modern organic pesticides is a milestone in the history of human struggle with pests. However, due to unreasonable use and the inherent problems of individual breeds, pest problems such as drug resistance, environmental pollution, poisoning humans and animals, and destruction of ecological balance have attracted worldwide attention. Researchers are trying to solve these problems in various ways, such as biological control, prevention and control of agricultural technologies, and development of insect resistant varieties. However, at present, it is widely studied at home and abroad and has made significant achievements in the search for bioactive substances from natural products. After being separated, purified and the molecular structure determined, it is used as a template for synthesizing new pesticides (such as pyrethroids, Toxic derivatives, etc.), has become a contemporary pesticide
