Abstract
The development, body weight, survivorship, and reproduction of the gram pod borer, Helicoverpa armigera (Hũbner), were evaluated in the laboratory at 25±5°C, 65±5% R. H. and a light : dark cycle of 16:8 h on six different cultivars of chickpea. The larval period ranged from 16.41 to 22.71 days on cultivars CMC-211s and Pb-2008 respectively. Similarly the larval period ranged 9.50 to 14.01 days on CMC-211s and Pb-2008 respectively. The average number of eggs oviposited by adults reared on Pb-2008, Bittal-98, Parbat, CM-2000, Dasht and CMC-211s were 299.68, 323.66, 353.36, 462.84, 492.28 and 522.54 respectively. The survival percentage survival of all larval instars of H. armigera ranged from 73% on comparatively resistant cultivars to 93% on susceptible cultivars of chickpea. Dasht, CM-2000, Parbat and Bittle-98 showed intermediate trend. Cultivar Pb- 2008 was resistant as compared to other cultivars.
