Spotted Wing Drosophila (aka SWD) has been found in Mississippi. Dr. Blair Sampson and his technician Chris Werle identified it in blackberries last week. I went out this morning to take a photo. See it below:
The SWD is the little beige colored spot in the middle of the fruit. It looks like your typical fruit fly. The USDA-ARS here in Poplarville are starting to look into this problem with greater detail, including trapping it. Other states have had more experience with this pest. Michigan State (http://www.ipm.msu.edu/swd.htm) and Oregon State (http://groups.hort.oregonstate.edu/group/spotted-wing-drosophila) have good, informative websites. Dr. Hannah Burrack from NC State has a blog that has covered SWD as well (http://ncsmallfruitsipm.blogspot.com/p/spotted-wing-drosophila.html). These are just a few of the possible links.
So far, we have not seen SWD in blueberries, but it would be foolish to think it will not occur at some point; therefore, we will be vigilant in our scouting for this pest.
