Abstract: One of the known transmission pathways of bovine leukemia virus (BLV) is bloodsucking insects. Against this background, this study investigated changes in BLV seroconversion in cattle by season on three private farms in Northern Hokkaido. Study results showed that no BLV seroconversion was observed during winter, a season without horse flies, and that all seroconversions occurred during summer. Thus, we collected horse flies which were observed sucking blood on cattle in public grazed fields and performed BLV detection tests in the insects. The tests showed that 75% of the total collected horse flies were BLV-positive. These results suggested the existence of vectors such as horse flies in grazing filed (in summer) was a risk factor of the spread of BLV infection in Northern Hokkaido.
