However, 51.3% of fifth
instars that fed on 50 DAP Bt cotton leaves pupated, and 87.1% of the pupae successfully developed into adults.
Of the unfed fifth instars (starved), 55.6% pupated and 88.1% of the pupae emerged. Pupae that developed from
larvae fed on Bt cotton leaves and unfed were significantly smaller, being 89.7 and 73.2% of the weight of the
pupae that developed from larvae fed on non-Bt cotton leaves.
