Effect of Bt cotton on survivability and development of Campoletis chlorideae (Uchida) parasitising Helicoverpa armigera (Hubner)

摘要

An experiment was undertaken to study the effect of Bt cotton on survivability and development of larval endoparasitoid, Campoletts chlorideae (Uchida) on Helicoverpa armigera (Hubner) under laboratory conditions. Results indicated that on Bt cotton there was no development of endoparasitoid as the host larvae itself killed immediately after feeding.
