The Walter Reed Biosystematics Unit (WRBU) is a world-renowned center of taxonomic excellence, undertaking cutting-edge research to provide actionable entomological intelligence tools and products that best assess global vector-borne disease risk. In partnership with the Smithsonian Institution, WRBU has grown the U.S. National Mosquito Collection from 200,000 specimens in 1961, into the world’s largest taxonomically and geographically comprehensive collection of over 1.7 million specimens today. WRBU also manages eight other families including sand flies, horse flies, black flies, biting midges, and four other families of non-biting insects.
