飞机释放群体饲养不育羊皮螺旋蝇[CochIiomyia hominivorax(Coquerel)],使其自然虫口在美国,墨西哥大部地区及加勒比海部分地区得到根除。目前,从墨西哥南部至特万特佩克地峡的螺旋蝇正在得到控制。由于螺旋蝇自然虫口整年存在,生产和释放有效的不育蝇是至关重要的。经年连续群体饲养后,更换工厂生产的螺旋蝇品系(以下简称工厂品系)的策略是取得根除计划成功的保证。虽然第一个工厂品系(佛罗里达品系)在1956年——1966年有较高的成功率,但也逐渐暴露出潜在的缺点。因此在群体饲养前,对那些后备工厂品系
Plane release groups were kept sterile Cochinchomycosis (Cochiomyia hominivorax (Coquerel)], so that its natural population in the United States, Mexico, most parts of the Caribbean and parts of the eradication. Currently, spiral flies are being controlled from the south of Mexico to the Gulf of Tvantepe. Due to the natural presence of helminthes throughout the year, it is crucial to produce and release effective infertile flies. After years of continuous group feeding, the strategy of replacing the helical fly strain (hereinafter referred to as the factory strain) produced by the factory is to ensure the success of the eradication plan. Although the first factory strain (Florida strain) had a higher success rate from 1956 to 1966, it gradually revealed potential shortcomings. Therefore, before the group feeding, those reserve plant strains
