Growers and an alert county agent, Ben Beale, have found what most likely will be an infestation of spotted wing drosophila (SWD) in cherries in southern Maryland (St. Mary’s County). I say "most likely" because I have the cherries and the maggots but it is very difficult to identify SWD from other fruit or vinegar fly maggots.
A few blueberry and cherry growers in central Maryland have reported fruit damage to their crop from Spotted Wing Drosophila (SWD) this week. If you grow any small fruit such as blueberries, cherries, blackberries, raspberries it would be best if you check these crops for the presence of SWD.
