The spotted wing drosophila (SWD) is an invasive pest of berries, stone fruit, grapes, and some pome fruit crops. It is native to Asia but was detected in North America for the first time in California during 2008. Since then, it has spread throughout many of the primary fruit production regions of the United States, including Michigan.
SWD was first detected in Michigan in late September 2010. First fly captures in recent years have been in early June, and this has happened again in 2015 with female SWD trapped in Berrien and Benzie counties in the second week of June.
We expect that this fly is distributed throughout the southern peninsula of Michigan. It has been found in farms, gardens, rest areas, and wild areas suggesting that it is well-established in this region.
