武汉大学研制的基因工程病毒杀虫剂，经过５年来的４次田间实验，取得理想效果，有望近期内投入批量生产。 据专家介绍，这种基因工程病毒杀虫剂主要用于杀除素有“蔬菜癌症”之称的甜菜夜蛾、小菜蛾和菜青蛾等害虫。实验表明，这种杀虫剂是一种高效、无公害生物农药，２～３天 The genetically-engineered virus insecticide developed by Wuhan University has achieved ideal results after four field experiments in five years and is expected to be put into mass production in the near future. According to experts, this genetically-engineered virus insecticide is mainly used to kill pests known as “vegetable cancers”, such as Spodoptera exigua, Plutella xylostella and Pieris moth. Experiments have shown that this insecticide is a highly effective and pollution-free biological pesticide and it can take 2 to 3 days.
