Interpretive Summary:

Technical Abstract: The invasive brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae) has recently emerged as a harmful pest of horticultural crops in North America and Europe. Native to East Asia, this highly polyphagous insect is spreading rapidly worldwide. Climate change will add further complications to managing this species in terms of both geographic distribution and population growth. This study used CLIMEX to compare potential H. halys distribution under recent and future climate models using one emission scenario (A2) with two different global circulation models, CSIRO Mk3.0 and MIROC-H. Simulated changes in seasonal phenology and voltinism were examined. Under the possible future climate scenarios, the invasion threat posed to Europe is likely to expand northward. In North America, suitable H. halys range shifted northward into Canada and contracted from its southern temperature range limits in the United States due to increased heat stress. Prolonged periods of warm temperatures resulted in longer growing seasons. However, future climate scenarios indicated that rising summer temperatures decrease H. halys growth potential compared to recent climatic conditions, which in turn, may reduce mid-summer crop damage. Climate change may increase the number of H. halys generations produced annually, thereby enabling the invasive insect to become multivoltine in the northern latitudes of North America and Europe where it is currently reported to be univoltine. These results indicate prime horticultural production areas in Europe and northeastern United States, and southeastern Canada are at greatest risk from H. halys under both current and possible future climates.
