| description | Based on preliminary experimental data, and a critical review of studies executed in North and South America, the possibility of the existence of two strains or biotypes of fall armyworm (FAW), Spodoptera frugiperda, in Colombia was studied. Moreover, its influence on the management of this polyphagous pest and the prospects of controlling the insect with transgenic corn and cotton hybrids that express one or more Bacillus thuringiensis toxins were analyzed and discussed. Based on the similarity of CL50 obtained during evaluations for tolerance to Bt toxin Cry1Ac of different FAW strains collected on different hosts and in diverse geographic regions, the existence of a strain that attacks both corn and cotton and another one that affects rice and pastures has been assumed. Populations collected from corn and cotton exhibited a tolerance up to 127 times higher than that of pasture population, which further showed a CL50 to the toxin Cry1Ab between 3.45 and 5.64 ppm. Likewise, some advances in the attainment of plant species, genetically transformed hosts of the insect with toxins different from those coming from Bt, have been shown and evaluated at an international level. |

Basado en datos experimentales preliminares y una crítica revisión de estudios realizados en Norteamérica y Suramérica, se analiza y se discute la posibilidad de la existencia en Colombia de dos razas o biotipos del cogollero del maíz, Spodoptera frugiperda, su influencia sobre el manejo de esta plaga polífaga y las perspectivas de su control con variedades o híbridos de maíz y algodonero transgénico que expresan una o más toxinas del Bacillus thuringiensis. Se propone, fundamentado en la similitud de las CL50 determinadas a través de evaluaciones por tolerancia a la toxina Cry1Ac del Bt de diversas razas del cogollero, recolectados en diferentes huéspedes y regiones geográficas, la existencia de la raza que ataca tanto maíz como al algodonero y la raza que afecta arroz y pastos. Poblaciones procedentes de maíz y algodón mostraron una tolerancia hasta 127 veces mayor que la población colectada en pastos. Esta última raza exhibió además una CL50 entre 3,45 y 5,64 ppm al Cry1Ab. Igualmente, se muestran y evalúan algunos avances a nivel internacional en la obtención de especies vegetales, huéspedes del cogollero, genéticamente transformadas, con toxinas diferentes a las procedentes del Bt, huéspedes del cogollero.
