随着国内首个生物农药工程技术国家级研究中心落户湖北,一种旨在剔除“农药残余”的生物农药进入产业化研发。玉米生长过程中,玉米螟的危害无疑是致命的。这种俗称钻心虫的害虫,以疯狂啃食玉米植株地上各部位为生,不过科学家发现,一种微生物却能侵入玉米螟体内,杀虫于无形之中。“杀死害虫的是一种名叫苏云金杆菌的微生物。”国家生物农药工程技术研究中心主任杨自文介绍,通过药剂喷洒,这种微生物产生的代谢物被玉米螟食用并进入其体内,让其患上败血病死亡,而对其他昆虫和动物无害。
With the establishment of the first national research center for biopesticide engineering technology in China, a bio-pesticide aimed at eliminating “pesticide residue” has entered the industrialized research and development. The damage of corn borer is undoubtedly fatal during the growth of corn. This commonly known as bore worms pests crazy to eat corn plants all parts of the ground a living, but scientists found that a micro-organisms can invade the corn borer body insecticide in the invisible. “To kill pests is a called Bacillus thuringiensis microorganisms. ” National Biological Pesticide Engineering Research Center Yang Ziwen introduction, through the pharmaceutical spraying, the metabolites produced by this microorganism was corn borer consumption and into its body, let It suffers from septicemia and is harmless to other insects and animals.
