The eradication of the screwworm, Cochliomyia hominivorax, from USA, Central America and the North of Africa has been achieved by rearing and releasing sterile males. Why we do not decide to eradicate this insect from the southamerican countries too? In this paper the scientific, ecological and economic reasons before taking such a courageous decision are discussed. The human botfly, Dermatobia hominis, has not been eradicated from any country, because there is so far no technique available for mass production in artificial diets. Studies on dispersion, sexual behavior and aggregation sites of the adults in the field are also not known. Why the neotropical myiases will continue to be treated basically with chemicals, recommendations for insecticide resistance management and studies on alternative methods are discussed trying to apply in the future an ecologically based pest management of the screwworm and the human botfly.
