In order to investigate a suitable carbohydrate-resources and the activities of starch decomposing enzymes in artifical diet of silkworm, the experiment was undertaken by adding eight kinds of starch in the diet of silkworm. Major characters and zymograms of amylase in body organs were studied by electrophoresis. The results obtained are as follows: 1. Starches of rice, barey and millet were comparatively good for maintaining practical characters of silkworm. 2. It is assumed that no treatments are need to increas purity of starch resources for artificial diet of silkworm. It was found that starch amounts adding to artificial diet are moeerate ranging 12 to 18 percent as dry weight. 3. Regardless of kinds of starch and varieties of silkwormr sametype of electrophoresis zymogram for amylase was resulted as three bands in hemolymph, four bands in intestine and two bands in intestine and two bands in silkgland. There was no band in the digestive juice. In case of 18 percent addition of starch and check plots, no amylose change was investigated in the hemolymph.
