abstract
Apparent mortality at early larval stage was revealed 10.00 percent to control condition (28±1°Ï¹). Highest Survival fraction 0.90 was recorded at egg stage and early instar and late instar larval was investigated 0.90 and 0.96 respectively. Pre-pupal and pupal stage survival fraction was recorded 0.96 and 0.91 at control condition (28±1°Ï¹). While, minimum 0.87 survival fraction at egg stage and early and late instar larval stage were recorded 0.839 and 0.958 percent at control condition (28±1°Ï¹). K-value is the key factor, which is primarily responsible for increase or decrease in number from one generation to another. The k-value 0.18 was observed at control condition (28±1°Ï¹).
