Present investigation was carried out on four different diets (Tender chickpea leaf, Chick pea socked grains, Green pea and Artificial diet) for different biological events growth and development were compared as different parameters such as larval period, pre-pupal period, pupal period, percent pupation, pupal weight and percent adult emergence along with embryonic development, eggs laying capacity of female, survivability of adult and sex ratio. The effect of different host on the biological growth and development of pod borer maximum larval period was recorded on green pea 19.43 days, pre-pupal period 1.76 and 1.43 days found on chickpea leaf and green pea than maximum pupal period 12.8 and 10.18 days recorded on same host. The maximum percent of pupation recorded on chickpea leaves 93.33% and on the same host highest adult emergence observed on 90.28%The maximum pre-ovipostional, ovipostional and post-ovipostional periods recorded on artificial diet 3.80, 6.16 and 2.19 days, highest fecundity recorded on artificial diet 770.59 eggs/female, the highest longevity of male and female recorded on chickpea leaf 7.86 and 13.13 days, the maximum sex ratio recorded 1:1.9 on artificial diet .The maximum growth index recorded on artificial diet 5.39 , the higher larval pupal Index and survival index recorded 1.19 and 1.05 on the chickpea leaf ,The maximum ovipostional index recorded on the artificial diet 1.00 ,The adult index of male recorded 1.00 same are all food material and female maximum recorded 1.00 on artificial diet and minimum 0.78 on chickpea grain.
