Weight distribution of backcross larvae tested in bioassays. (A) Backcross family 9B was tested with the survival bioassay (10 μg of Cry1Ac per ml of diet for 21 days). Of 58 larvae tested, 30 were heavy (>10 mg), 13 were light, and 15 died. (B) Family B9 was tested with the growth bioassay (1 μg of Cry1Ac per ml of diet for 11 days). Of 60 larvae tested, 30 were heavy (>20 mg), 27 were light, and 3 died.
