田间害虫一直是人类的大敌,从人类开始种植农作物时起,就与各种害虫开始了一场永不停止的斗争。千百年来,人类所使用的武器不断更新,从最原始的方法发展到今天的各式各样的杀虫剂、复合农药,而害虫也不断产生新的抗药性。今天人们已经认识到,单靠化学杀虫剂害多利少,残留的农药造成了严重的环境污染,最终会聚集到人的体内。由于大量的施用化肥,已经造成了土壤板结地力下降,长此下去,还会造成不可挽回的损失。因此各国的科学家都在竞相研究非化学方法消灭害虫,最近英国牛津大学的科学家就研究出了一种很有趣的消灭害虫的新方法——让害虫饿死。英国牛津大学病毒研究所的一个研究小组采用遗传工程技术把一种叫做“返幼激素酯酶”的基因引 Pests in the field have always been the enemy of mankind, starting from the time human beings began to plant crops, they started a never-ending struggle with various pests. For thousands of years, the weapons used by mankind have been constantly updated, developing from the most primitive methods to a wide range of pesticides and complex pesticides today, and pests have been continuously generating new resistance. Today people have come to realize that chemical insecticide alone harm less, residual pesticide caused serious environmental pollution, will eventually be gathered in the human body. Due to the large amount of fertilizers applied, soil compaction has been reduced, which will lead to irreparable losses. Therefore, scientists from all over the world are competing to study non-chemical methods to eliminate pests. Recently, scientists at the University of Oxford in the United Kingdom developed an interesting way to eliminate pests - starving pests. A team of researchers at the Institute of Virology at Oxford University in the United Kingdom used genetic engineering to introduce a gene called “juvenile hormone esterase”
