Abstract. — Chilocorus kuwanae, a coccinellid predator of euonymus scale, Unaspis eu- onymi (Comstock) (Homoptera: Diaspididae), was introduced from Korea (1984) and Japan (1985) into the United States. The beetle was released in 25 states in the eastern half of the country and became established in nine states (CN, DE, MA, MD, MI, NC, NJ, OH, PA) and the District of Columbia.
