Comparative development,survival and fecundity of helicoverpa armigera (hubner) (lepidoptera: Noctuidae) on different chickpea cultivars

The development,body weight,survivorship,and reproduction of the gram pod borer,helicoverpa armigera (hbner),were evaluated in the laboratory at 255c,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. copyright © 2016 zoological society of pakistan.
