| description | The official authorization for planting Bt maize in most Central and South American countries was granted more than 20 years ago. This permission has raised concerns, has revealed inconsistencies in the information provided for farmers, has shown unknowns, motivating comments, and produced publications, often not scientific. Given the theoretical impact on environment, economy, and health, and the development of fall army worm´s resistance, despite the existing research capacity in these countries, the scientific literature is scarce, probably due to lack of funding and influence by the holders of the patents and the producers and traders of seeds of transgenic maize. The aim of this review is to debate the benefits and disadvantages originated by the sowing of the maize hybrids that contain any of the different Cry´s of the bacteria Bacillus thuringiensis. The documents reviewed do not elucidate conclusions; it will be necessary to wait years to define if the transgenic maize plantings represented a benefit for the growers and consumers of this plant species, which originated in these areas. However, at this moment an existing balance between the benefits and the risks of Bt maize plantings could be deduced. |

La autorización official de siembras de Bt maíz fue otorgada en la mayoría de los países de Centro y Sur-América hace más de 20 años, lo que ha despertado inquietudes, revelado inconsistencias en la información producida para los agricultores, mostrado incognitas, motivado comentarios y producido publicaciones, a menudo no científicas. Dado el impacto teórico, ambiental, económico y salubridad y desarrollo de resistencia del cogollero del maíz, se considera que a pesar de la capacidad investigativa existente en estos países, la literatura científica reciente es más bien escasa, probablemente, por falta de financiación de estudios y la influencia de los dueños de los patentes, de la producción y venta de semillas de maíz transgéncio. Con esta revisión, se pretende relacionar los beneficios y desventajas originados por la siembra de los híbridos de maíz a los que se han incorporado Crys de la bacteria Bacillus thuringiensis. De los documentos revisados, todavía no se desprende una conclusión definitiva; habrá que esperar años para poder definir si las siembras de maíz transgénico representaron un beneficicio para los cultivadores y consumidores de esta especie vegetal originaria de esta zona. Sin embargo, en este momento se podría deducir que existe un equilibrio entre los beneficios y los riesgos de las siembras de maiz Bt.
