Bombus terrestris is imported and now commercially produced, while B. ignitus is the native bumblebee species, which is in the process of commercialization in Korea. For the successful rearing, understanding the body composition is important parameter to understand the diet requirement. We measured and compared body fat and amino acid composition of two bumblebee species under mated condition. The results revealed that there was significant difference in the body weight of two tested species. The quantity of body fat (fatty acids) and proteins (amino acids) was found higher in B. ignitus than that was reported for B. terrestris. However, individual fatty acid and amino acid distribution was similar in both species. Dominant fatty acids were oleic acid and palmitoleic acid of among monounsaturated fatty acid, palmitic of saturated fatty acid, and linoleic acid of polyunsaturated fatty acid. Among amino acids, glutamic acid was predominant followed by glycine and leucine. To foster the population of native bumblebee i.e. B. ignitus through rearing, appropriation of feed formulation could be based on this result which could lead the purpose of feed development for indigenous population.
