This study was conducted to evaluate the time required to sell Protaetia brevitarsis larvae when larvae fed on three kinds of fermented berries sawdust, such as mulberry, raspberry, and blueberry. The first instar larvae were reared in a plastic container(543x363x188mm) with designated feeds, and investigated the cumulative proportion of larvae more than 2.5g at rearing room regulated at 25±1℃ with 50~60% under 16:8(L:D). When we reared larvae for about 45 days with fermented blueberry sawdust, the cumulative proportion of larvae with more than 2.5g was over 70%. It was about 40 days shorter than fermented oak sawdust. For each group, the average survival rates of larvae at the possible time for sale were 72~93%.
