Welcome

Thanks for visiting the Steffan Lab web page.  We are proud to serve the Wisconsin cranberry industry, which leads the nation in cranberry production.  Our research centers on basic and applied aspects of cranberry entomology.  We strive to improve our understanding of the biology and ecology of insects within the cranberry system, to improve our state’s commercial growing conditions and preserve the surrounding environment.

Read about lab news, research updates and relevant resources on our blog.  Check out some of our sweet cranberry videos, here:

Cultivated cranberry is Vaccinium macrocarpon, but in the wild that species grows along with Vaccinium oxycoccos. This is the latter species, which can be distinguished from the former in part by the slightly pointed tip of the leaves.
