Increased activity of a hybrid Bt toxin against Spodoptera frugiperda larvae from a maize field in Cuba
Biotecnología Aplicada（2006）
Abstract
Spodoptera frugiperda is the most important maize pest in Cuba. The activity of seven Bacillus thuringiensis Cry1 toxins (five wild-type and two domain-swapped) was investigated in bioassays against newly hatched larvae from adults collected in a Cuban maize field. The CryAAC (1Ac/1Ac/1Ca) hybrid showed the lowest effective dose (50% lethal dose, LD50) of 288 ng/cm 2 contrasting with parental Cry1Ca and Cry1Ac, which were not lethal (LD50 >
