Comparative effect of natural diets and semi synthetics diet on Helicoverpa armigera (Hubner) in development and growth index

Abstract

The present study was conducted to evaluate the comparative effect of natural diets and semi synthetics diet on Helicoverpa armigera (Hubner) in development and growth index. Among all the six different diets on the growth and development of the larvae of gram pod borer (H. armigera), The artificial diets (chickpea flour based diets) to be the most suitable which resulted longer larval period, pre-pupal period, pupal period. Maximum percent adult emergence, highest fecundity, sex ratio, growth index, pupal index, survival index and ovipositional index along with success index of different stage of H. armigera compared to the main diets of chickpea, mungbean and urdbean leaves and pods (control).
