Having conducted numerous research and survey projects, Korea National Arboretum (KNA) has been a centre for Korean insect diversity researches in South Korea for about a decade since its first step as the first national biological collection was taken in 2003. Those projects mainly focused on specimen collection through various surveys and classical taxonomic studies on rather limited taxa. Holding slightly more than 6,000 species in our collection now, we consider it is time to take another approach that will keep insect researches going and expanding its boundary although it seems a little bit late to follow an international trend. The approach we are about to follow is a DNA barcode blitz, which aims for rapid digitization and sequencing of insects. With an integrated system of insect taxonomy we may provide faster and more reliable identification service to the public and other related biological and ecological studies. Digitized morphological and molecular data can be used in various ways such as forest insect pest monitoring, climate change related monitoring, and reverse taxonomic study.
