美国农业部计划在墨西哥和德克萨斯南部培育和释放数十亿只无菌苍蝇,以对抗食肉性螺丝蝇,因为食肉性螺丝苍蝇会杀死牲畜和宠物。 The U.S. Department of Agriculture plans to breed and release billions of sterile flies in Mexico and southern Texas to combat the flesh-eating screwworm fly, which can kill livestock and pets. 不育的雄性苍蝇将与野生雌鸟交配,防止生儿育女,并消灭害虫人口。 The sterile male flies will mate with wild females, preventing offspring and collapsing the pest population. 美援署将投资850万美元用于德克萨斯州分配中心,2 100万美元用于转换墨西哥设施,目的是每周生产多达4亿只无菌苍蝇。 The USDA will invest $8.5 million for a Texas distribution hub and $21 million to convert a Mexican facility, aiming to produce up to 400 million sterile flies weekly.
