Early Detection, Forecasting, and Management of Halyomorpha halys

$597,795 to create a multi-stakeholder, comprehensive approach for early detection and forecasting, via phenology and climate change models, to improve the timing of management strategies for the brown marmorated stinkbug.

Winter 2017 update

The brown marmorated stink bug (BMSB), Halyomorpha halys, is recent invasive species in the U.S. that is native to Asia. BMSB was first detected in the U.S. in the mid-1990s, but was not found in Minnesota until 2010. As with many stink bug species, BMSB has a wide host range, attacking >250 plant species, including many fruit, vegetable and field crops of economic value. The bug is also a severe nuisance pest, as it often invades homes, commercial buildings and other structures during autumn in search of overwintering sites. Given the previous experience of entomologists in the U.S., the primary crops at risk in Minnesota include corn, soybean, sweet corn, tomato, wine grapes, strawberry, and raspberry. Where BMSB has become established, significant increases in economic losses and pesticide use have greatly disrupted crop production. The focus of our project includes three broad objectives: a) development of new monitoring tools for early, consistent detection of BMSB in Minnesota (via new traps and a new app, the “Midwest Stinkbug Assistant”) to help farmers, crop consultants and homeowners correctly identify BMSB; b) conduct new studies of BMSB population dynamics and develop forecasting models, to understand how and where this pest is invading and colonizing the state; e.g., to determine the number of generations per year relative to the onset of winter; and c) to compare validated forecasting models of BMSB to current and future climate conditions.  Advancements in each of these areas will contribute to improved management programs while minimizing unnecessary insecticide use.
