Bumblebees are important pollinators in greenhouse and have colonized all parts of the World. In Korea, the value of bumblebees is increasing as pollinator. However, the more recent use of reared colonies may ultimately allow pathogens to spread to peripheral areas for bumblebees. Generally, bumblebees are hosts to a large number of parasites which are mites, flies, protozoa, fungi, virus and bacteria. For most of these, very little is known about their effects against host insect, epidemiology or evolutionary ecology. So, we report pathogenic bacteria isolated from Bombus terrestris and B. ignitus at first time in Korea. Bacillus fusiformis and Klebsiella oxytoca are isolated from B. terrestris and confirmed with 16S rRNA gene nucleotide comparison in NCBI genebank. Pathogenicity of B. fusiformis was 35~40% against B. terrestris. Pantoea dispersa and K. oxytoca are isolated from B. ignitus and confirmed with 16S rRNA gene nucleotide comparison in NCBI genebank. Pathogenicity of these species were 35~40% against B. ignitus. These pathogenicity are considered as low-level.
