Resistance to Biotech Crops Is on the Rise

Caption: By 2011, the area planted worldwide to genetically engineered Bt corn and Bt cotton increased to 66 million hectares (160 million acres) and the number of pest species with resistance causing reducing efficacy of Bt crops climbed to five. The asterisk indicates the number of resistant pests could be underestimated for 2011 because reports of field-evolved resistance typically are published two or more years after resistance is first detected.
