Abstract

Three principal diets were used for the nutritional study of the red-banded leaf roller, Argyrotaenia yelutinana (Walker). One was the Fava bean plant, Vicia faba (L.), which was used as a check for growth, development, and reproduction. The other 2 were agar based. One agar-base diet, called the Fava bean medium, contained lyophilized Fava bean leaves, yeast extract, dextrose, salts, bacto-peptone, and water as the sources of the dietary requirements. The third diet, called the casein medium, contained dextrose, salts, casein, 4 amino acids, ribose nucleic acid, linseed oil, cholesterol, vitamins, and water. Growth and development on the Fava bean medium was comparable to that attained on the Fava bean plant. However, the larval growth period on the casein medium was longer and resulted in an increase in body weight over that attained on the Fava bean medium. In the adults, both scale condition and longevity were similar for the insects reared on the 2 media. Growth, development, and reproduction of a second generation reared axenically from egg to adult on the casein medium were similar to those attained in the first generation. Six generations were reared axenically from egg to adult on the casein medium and 3 on the Fava bean medium.
