Managing the Japanese Beetle: A homeowner's Handbook (PDF)

The Japanese beetle (Popillia japonica Newman) is a highly destructive plant pest of foreign origin. It was first found in the United States in a nursery in southern New Jersey in 1916. In its native Japan, where the beetle’s natural enemies keep its populations in check, this insect is not a serious plant pest.
