农业中用以控制有害生物的经济成本是非常难估量的,如病虫害这样的生物威胁约可占全球粮食损失的40%。预计到2017年,全世界花费在杀虫剂上的费用约为650多亿美元。同时开发只针对有害生物,而极少对有益生物造成伤害的“绿色”杀虫剂成为一种迫切的需要。来自包括德国科隆大学动物研究所在内的国际科学家团体正在开发新的、生物友好型杀虫剂,由此降低大量害虫对作物产生的危害。2020年开始,欧盟的研究与创新基金将获准700万欧元启动研究开发经筛选的集中昆虫激素系统。研究人员意在用人工合成 The economic costs of controlling pests in agriculture are extremely difficult to measure. Biological threats such as pests and diseases can account for about 40% of global food losses. It is estimated that by 2017, the cost spent on insecticides worldwide will be about 650 billion U.S. dollars. It is also urgent to develop “green” insecticides that target only pests at the same time with minimal harm to beneficial organisms. International groups of scientists, including the Institute of Zoology at the University of Cologne, Germany, are developing new, bio-friendly insecticides to reduce the harmful effects of large numbers of pests on crops. Starting in 2020, the EU’s Research and Innovation Fund will be approved for € 7 million to start research and development of a screened concentrated insect hormone system.
