A, Mean (+1 se) mass of 20 replicate M. sexta larvae fed on individual plants from each of the three N. attenuata asGLP T2 lines (A860-19, A871-16, and A911-10) and one wild-type, untransformed line (WT) plants, 2, 4, and 6 d after the larvae hatched and were placed on plants. B, Percentage of T. notatus adult and nymphs per plant on A860-19 versus wild-type, A871-16 versus wild-type, and A911-10 versus wild-type pairs, 4 d after four-replicate plant pairs were exposed to 80 to 100 insects. Asterisks indicate significant differences between members of a pair (each asGLP line versus wild-type lines, P < 0.05, Student's t test).
