Penn State scientists will study stink bugs as they relate to the production of tree fruits, vegetables and grapes. Researchers will explore biological control options, stink-bug chemical ecology (chemically mediated interactions among plants and insects), and monitoring strategies. The project also will assess the pest's economic impact and the economic feasibility of new management methods.

Krawczyk said although the research will focus mostly on specialty crops and will not directly address infestations in homes or in major agronomic crops such as corn and soybean, knowledge gained should aid in the development of recommendations that could be useful for habitat-scale management.

Other Penn State personnel taking part in the project include David Biddinger, senior research associate in entomology at the Fruit Research and Extension Center; Gary Felton, professor and head of entomology; Shelby Fleischer, professor of entomology; Jayson Harper, professor of agricultural economics; Steven Jacobs, senior extension associate in entomology; Michael Saunders, professor of entomology; and John Tooker, assistant professor of entomology.

The project is led by USDA's Agricultural Research Service, along with a core group of land-grant universities: Penn State, Rutgers, Virginia Tech, and the universities of Maryland and Delaware. Also participating are researchers from Cornell, Oregon State University, North Carolina State University, Washington State University and the Northeast IPM Center.
