Abstract or Summary

The present study aimed to evaluate under field conditions, the effect of genetically modified maize hybrids in control of Spodoptera frugiperda, Elasmopalpus lignosellus and Diatraea saccharalis, to identify Trais which is more efficient in controlling this complex caterpillars. The experiment was conducted in city of Lucas doRio Verde, State of Mato Grosso, Brazil, the experimental design was randomized blocks with six treatments consist of transgenic materials: Cry1Ab, Cry1F, Cry1A.105+ Cry2Ab2 and Vip3Aa, and the conventional material with and without insecticide application. For the environmental conditions of this study, the genetic materials with biotechnology Cry1F, Cry1A.105 +Cry2Ab2 and Vip3Aa entered the hybrids were the highest yields of maize, as well as those with lower intensities damage from S. frugiperda. Regarding the control of E. lignosellus, only the conventional and hybrid technology Vip3Aa were susceptible to this insect pest incidence. All biotechnology inserted into maize hybrids were effective for control of D. saccharalis.
