We determined the geographic spread of the invasive hornet, Vespa velutina nigrothorax which had established in Young-do, Busan in Southeastern Korean since 2003. After invasion, the hornets is expanding its distribution. Yearly dispersal was estimated as 9.4 Km northward. Distribution area increased exponentially reaching ap. 70% of total districts. CLIMEX model analysis indicates that the ecoclimatic indices (EI) increased as the projection year increased based on RCP8.5 scenario. Because of the lack of the correlation between the estimated EI values and actual distributional value, we project that this type of spread will continue to certain period. Given the important risk and impact on beekeeping, socio-biological as well as ecosystem and biodiversity levels, careful monitoring of phenology, range expansion and preventive efforts mitigating the impact are further required.
