Adult flies have been found in Izard, Johnson and Washington counties, according to a news release.
Suspect larvae were found in blueberries in Pope, strawberries in Van Buren and blackberries in Johnson counties.
Unlike most fruit flies that seek out rotting fruit on which to lay eggs, spotted wing drosophila females look for fruit just nearing maturity in which to oviposit.
Growers should monitor for the fly.
This can be easily done by creating traps of plastic jugs filled with a bat of apple cider vinegar, flour and yeast.
