Growth of red flour beetleTribolium castaneum (Herbst) larvae with brown or milled rice as the carbohydrate source was faster on diets containing milled rice than on those with brown rice. Larval growth was negatively correlated with amylose content of both brown and milled rice. Among high-amylose (>25%) milled rices, heavier larvae were obtained with rices of low gelatinization temperature (alkali-spreading values 6–7) than with those with higher gelatinization temperature (alkali-spreading values < 6). The differences in larval growth reflected relative digestibility of raw rice starch granules.
