Effects of transgenic Bt corn on growth and development of the stalk borer Papaipema nebris (Lepidoptera: Noctuidae)

Authors: Binning, R.R., Rice, M.E.
Journal, Volume, Year: Journal of Economic Entomology, volume 95(3):622-627, 2002
Summary

Assessed efficacy of Bt 11(Cry1Ab) and event CBH351 (Cry9C) against stalk borer Papaipema nebris. Growth and development were slowed in Bt corn and mortality was higher. Showed reduced weight of larvae on Bt plants.

Comments

Potential of chronic effects in species that are not susceptible enough to have 100% mortality.
