Abstract


This study evaluated the effect of four different feeds on the larval weight and survival rate of Protaetia brevitarsis seulensis (PBS) over five weeks. Four different types of feed (self-fermentation medium, RM medium, Samsung livestock medium, and bean-curd dregs medium) were given to third-instar larvae of PBS. Weight changes and survival rates of PBS larvae were measured weekly for five weeks. During the experimental period PBS larvae showed the highest growth in Samsung livestock medium, followed by bean-curd dregs medium, RM medium, and self-fermentation medium. Survival rate of PBS larvae were the lowest in bean-curd dregs medium, and then in the Samsung livestock medium. Using the Samsung livestock medium can shorten the delivery period of PBS larvae by approximately 40 days based on the larva shipped on average 75 days. Therefore, this study provides information and data on insect farming techniques useful for insect industrialization.
