Scientific Name: 

Popillia japonica Newman, 1841 (ITIS)

Common Name: 

Japanese beetle

Native To: 
Date of U.S. Introduction: 

First discovered in 1916, but was probably introduced around 1911 (Potter and Held 2002)

Means of Introduction: 

Possibly in the soil of imported ornamental plants (Potter and Held 2002)


Destructive pest of turf, landscape plants, and crops; adults feed on the foliage and fruits of several hundred species of trees, shrubs, vines, and crops, while larvae feed on the roots of grasses and other plants (APHIS 2015)

The Japanese beetle (Popillia japonica Newman) is a highly destructive plant pest of foreign origin. It was first found in the United States in 1916 and has since spread to most states east of, and immediately to the west of, the Mississippi River. It has also spread to some western States, but tough regulations and careful monitoring have prevented its establishment elsewhere. The Japanese beetle has become a serious plant pest and a threat to American agriculture.

Scientists with USDA’s ARS and APHIS have developed an integrated pest management (IPM) program that combines biological, cultural, and chemical strategies. In support of this plan, the Midwest Climate Hub Fellow, Dr. Erica Kistner-Thomas modeled how climate change may impact the distribution and voltinism (generations produced per year) of the Japanese beetle. Model projections indicate increases in temperature would enable northward range expansion across Canada while simultaneously shifting southern range limits in the United States northward. For more on Erica’s work, see: The Potential Global Distribution and Voltinism of the Japanese Beetle (Coleoptera: Scarabaeidae) Under Current and Future Climates.
