国家“863计划”课题“转基因抗虫小麦”育种日前通过专家鉴定,这标志着我国转基因小麦育种取得突破。蚜虫病是危害小麦的主要害虫之一,特别是在我国东部小麦生产区。蚜虫在取食时分泌一种粘液,会降低叶片的光合作用效率,其刺吸式口器刺入叶片时也会产生伤口,传播多种病毒。长期以来,我国主要靠喷施杀虫剂来防治,在杀死蚜虫的同时,杀虫剂也会消灭蚜虫的天敌,破坏生态环境。 National “863 plan ” subject “transgenic insect-resistant wheat ” breeding recently passed the expert appraisal, this marks our country breeds of transgenic wheat made a breakthrough. Aphids are one of the major pests that endanger wheat, especially in the eastern wheat-producing areas of our country. Aphids secrete a mucus during feeding, will reduce the efficiency of photosynthesis of leaves, the piercing mouthparts piercing the leaves will produce wounds, spread a variety of viruses. For a long time, insecticides are mainly controlled by spraying insecticides in our country. While killing aphids, insecticides also destroy the natural enemies of aphids and destroy the ecological environment.
