Several artificial diets have been screened for rearing Eri silkworm, Philosamia ricini. The newly hatched larva could develop to adult stage on some diets. The cocoon shell ration was almost the same as that reared on natural host plant, but the survival percentage was lower. The highest percent of pupation was 51.25%. Biotin, cholesterol and wheatgerm oil were found to be essential for increasing pupation. Different compositions of artificial diets were studied to rear fourth and fifth instars of Bombyx mori. The results indicated that the larvae could develop to adult stage, however, the cocoon was smaller than that reared from mulberry leaves. The protein requirements were also studied. Mungbean powder was the most active protein source among those beans available in Thailand
