美找到推迟害虫产生抗药性新方法美国科学家找到一种新方法,可有效减缓农业害虫通过遗传而产生的抗药性。试验结果表明,在某些情况下,这种新方法可使害虫产生抗药性的时间推迟几十年甚至上百年。目前,一种杀虫剂一旦使用多年,害虫就会对它产生抗药性,人们不得不用另一种化学药剂来替代,直至害虫再次“适应”。然而,新发明的 NCR 方法通过混合使用多种杀虫剂,可十分方便地测出一种特效药剂来控制已对某种杀虫 United States to find new ways to delay the emergence of pest resistance American scientists to find a new method that can effectively reduce the resistance of agricultural pests through genetic resistance. Test results show that in some cases, this new method can delay the pest insecticide time delay of tens or even hundreds of years. At present, pests are resistant to pests once they have been used for many years, and people have to replace them with another chemical until they “adapt.” However, the newly invented NCR method, by mixing a plurality of insecticides, makes it very easy to measure an effective agent to control the insecticide
