随着害虫对常规杀虫剂抗性的不断增加,以及化学农药对人类和环境的影响所引起公众广泛的关注,人们对可作为取代害虫防治剂的生物农药产生了很大的兴趣.许多生物技术公司正从事于从大量的资源中寻找微生物毒素并进行遗传改良,许多有雄心的年轻科学家正致力于这些微生物毒素的作用方式到有效使用策略等方面的研究.1985年全世界所用杀虫剂的总金额估计为42.6亿美元,其中生物农药的销售额现在不到1%,估计到2000年可达到50%.
Pesticides have attracted a great deal of public interest as biopesticides replacing pest control agents due to their increasing public resistance to conventional insecticides and to the effects of chemical pesticides on humans and the environment. Many organisms Technology companies are engaged in the search for microbial toxins from genetically plentiful sources and genetically modified, and many ambitious young scientists are working on the ways these microbicidal toxins work and their strategies for effective use.1998 Pesticides used throughout the world in 1985 The total amount is estimated at 4.26 billion U.S. dollars, of which less than 1% of biopesticide sales are now estimated to reach 50% by the year 2000.
