日本农业科研人员利用基因工程培育的一种水稻能够使一种抗栗蚕蛾幼虫的生物杀虫剂效力大增。研究人员介绍,向水稻植株的细胞內注入一种有增强病毒作用的基因,可使病毒制剂的杀虫剂效力提高40倍。这种病毒制剂可使某些害虫的消化道感染一种病毒。人们把这种农药喷
A rice cultivar genetically engineered by Japanese agricultural researchers is capable of making a biopesticide that is resistant to chestnut moth larvae more effective. The researchers introduced into the cells of rice plants have a role in enhancing the role of the virus genes, the pesticide efficacy of the virus can be increased by 40 times. This virus preparation can infect the digestive tract of some pests with a virus. People spray this pesticide
