Strong Fitness Costs of Fall Armyworm Resistance to Dual-Gene Bt Maize Are Magnified on Less-Suitable Host-Crop Cultivars

Strong Fitness Costs of Fall Armyworm Resistance to Dual-Gene Bt Maize Are Magnified on Less-Suitable Host-Crop Cultivars

We examined the fitness costs of resistance to transgenic Cry1A.105+Cry2Ab2 <i>Bacillus thuringiensis</i> (Bt) maize in the fall armyworm, <i>Spodoptera frugiperda</i>, a globally invasive pest species. Using Bt-resistant and -susceptible populations of similar genetic backgr...
