Abstract
One of the arguments for the rapid adoption of genetically modified (GM0 corn in Brazil is the economic advantage that this technology can offer. Given that its benefits and gains are subject to the conditions of modifications of critical variables, the present work aimed to estimate the economic returns of Bt (Bacillus thuringiensis) corn by analyzing variations in quantities and prices of insecticides used, productivity gains, the price of using GM seed compared with non-GM seed, as well as changes in corn prices. It was concluded that the GM technology generated net economic gains of US235.50/ha.Umdosargumentosparaaraˊpidaadoc\ca~odemilhotransge^niconoBrasileˊavantagemecono^micaqueestatecnologiapodeoferecer.Considerandoquetantoosbenefıˊciosquantoosganhosesta~osujeitosaˋscondic\co~esdealterac\ca~odevariaˊveiscrıˊticas,foiobjetivodestetrabalhodimensionarosretornosecono^micosdosoptantesdomilhoBt(Bacillusthuringiensis),apartirdaanaˊlisedevariac\ca~odasquantidadeseprec\cosdeinseticidasutilizados,ganhosemprodutividadeevariac\ca~odosdiferenciaisdeprec\cosdesementesdemilhoBtemrelac\ca~oaˋssementesconvencionais,bemcomoavariac\ca~odosprec\cosdemilho.Observaram−seganhosecono^micoslıˊquidosmeˊdiosdeR555,79/ha, favorável à semente Bt
