Brown marmorated stink bugs are an invasive pest which causes a lot of mid-summer damage to many Southeastern crops, but especially to fruit orchards. A recent study which looked at the likely range of stink bugs in a warmer climate shows that the bugs may migrate to the north and out of the Southeast in the future due to the adverse effects of heat stress on their reproduction. But warmer winters will allow more overwintering of bugs in the future, which will caused increased problems for northern producers.

Here is a description of the research from the Midwestern Regional Climate Center:
The invasive brown marmorated stink bug (BMSB) is a harmful horticultural pest in the United States. Originally from East Asia, this pest is spreading rapidly worldwide and is especially problematic for tree fruits (apples and peaches). As with many invasive insects, climate is likely the dominant force determining BMSB distribution and densities in its range, given the lack of natural enemies and an abundance of suitable host plants. Climate change will add further complications to managing this species as it will influence its range limits.
In this study, the geographic distribution and population dynamics of BMSB were modeled under current and projected future climate scenarios. Climate change enabled BMSB to expand its range northward to higher latitudes in North America while suitable BMSB range in southeastern United States contracted. Under future climate change scenarios, BMSB exhibited earlier spring emergence, longer growing seasons, and more possible generations per year. These results indicate prime horticultural production areas in the Northeastern and Midwestern United States are at greatest risk from BMSB under both current and possible future climates. This work highlights areas of emerging or increasing risks posed by BMSB and can be used to inform biosecurity planning and pest management in light of a changing climate.
