Comparative Development, Survival and Fecundity of Helicoverpa armigera on Different Chickpea Cultivars

The development, body weight, survivorship, and reproduction of the gram pod borer, Helicoverpa armigera (Hubner), were evaluated in the laboratory at 255°C, 655% 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 cul...

Description
Summary:The development, body weight, survivorship, and reproduction of the gram pod borer, Helicoverpa armigera (Hubner), were evaluated in the laboratory at 255°C, 655% 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.
