WAUSAU, Wis. — Entomologist Phil Pellitteri says the Japanese beetle has more impact than any other 10 insects he can put together.

Pellitteri recently spoke at the Master Gardener Program in Marathon County, part of the University of Wisconsin-Extension. The closer one lives to a maintained irrigated lawn such as a golf course the more likely Japanese Beetles will be around, he said. They thrive in such conditions. They feed on more than 300 different host plants.
