An experiment was carried out to investigate the protein and carbohydrate requirements of the rice stem borer larvae during their thirty day period of growth. This period was devided into two fifteen day periods termed as early and late periods. The data obtained showed clearly that the larvae require protein rich food both during early and late stages of their growth and that the high protein requirements are more distinct in the early stages than in the late growth stages. Thus these requirements are different from the European corn borer because in the latter, during its late stages of growth, carbohydrate requirements are greater.
