discovery and characterization of field resistance to bt maize: spodoptera frugiperda (lepidoptera: noctuidae) in puerto rico.	transgenic maize, zea mays l., event tc1507 produces the cry1f protein to provide protection from feeding by several important lepidopteran pests, including spodoptera frugiperda (j.e. smith) (lepidoptera: noctuidae). reports of reduced field performance against this species in puerto rico were investigated, and laboratory bioassays showed that s. frugiperda collected from the affected area exhibited lower sensitivity to the cry1f protein compared with typical colonies from other regions. the re ...	2010	20857709
fitness costs of cry1f resistance in two populations of fall armyworm, spodoptera frugiperda (j.e. smith), collected from puerto rico and florida.	the development of resistance in target pest populations is a threat to the sustainability of transgenic crops expressing bacillus thuringiensis (bt) proteins. fall armyworm, spodoptera frugiperda (j.e. smith), is a major target pest of bt maize in north and south america. this insect is the first target pest that has developed field resistance to bt maize at multiple locations in these regions. the objective of this study was to assess the fitness costs associated with the cry1f resistance in t ...	2015	25791021
