Artificial diet (AD) has shown with different advantages over mulberry leaves (ML). Various types of such feed for silkworm have been developed and proposed. The aims of this study were possibility rearing whole instar of silkworm on AD and to find some economic formulation for rearing silkworm, compare to that ML. Eleven ADs (D$_1$ to D$_{11}$) were prepared with different percentage of mulberry leaf powder, and other ingredients such as soybean meal, cellulose, potato starch, agar, wheat flour, rice bran, etc. Five formulated diets (D$_1$ D$_2$, D$_{5}$, D$_{10}$ and D$_{11}$) appeared to have similar response to that ML (D$_{m}$). There were no significant differences for duration period between ADs, all of which recorded with higher duration than mulberry leaves. Compared to other died used in the present study D$_1$ and D$_{10}$ showed better growth development and survival rate. Larvae fed D$_1$, D$_2$, D$_{5}$, D$_{10}$ and D$_{11}$ grew faster and produced heavier and more useful cocoons.coons.coons.coons.
