LEP2.1 is an engineered three-domain crystalline protein active against fall armyworm, Spodoptera frugiperda J. E. Smith. This protein is an engineered variant of a novel Cry1B that shows a 33-fold increase in bioactivity against S. frugiperda in diet bioassay as compared to the parent Cry1B. Additionally, LEP2.1 is bioactive in both diet bioassays and maize, Zea mays L., plants against Cry1F resistant and Vip3A resistant S. frugiperda strains derived from both the US and Brazil. Further results from greenhouse and field studies conducted in the US (mainland and Puerto Rico) and Brazil will be discussed.
