Protaetia brevitarsis larvae have been widely used for traditional medicine and food in East Asia. This research comprised two experiments. The first experiment compared the growth in densities (10, 20, 30 larvae), substrates (commercial, self-made), and containers (Tyvek, zipper bags). In the second experiment, different numbers of air holes (16, 32, 48 holes) in zipper bags experiment is ongoing. The results indicated that the larvae development rate was 72.6%, 69.98%, and 55.33% in 10, 20, and 30 larvae densities, respectively. However, there was no significant difference in larvae survival rate and weight. In the different feed material experiments, the average larvae weight of commercial feed was 1.09g and for self-made, it was 2.85g. The survival rate was 86% and 96% in commercial and self-made feed, respectively. Lastly, while 96% of larvae survived in Tyvek bags, none of the larvae survived in the zipper bags.
