Here's info about cherry and spotted wing fruit flies:
Early summer when fruit flies emerge (about Memorial Day) | • Cherry fruit fly | –carbaryl, esfenvalerate, malathion, pyrethrins, or spinosad –Applications may need to be repeated at 7- to 14-day intervals. Use traps to properly time treatments. |
Spotted wing drosophila | – carbaryl, esfenvalerate, malathion, pyrethrins, or spinosad –Applications may need to be repeated at frequent intervals. Fruit becomes susceptible to attack around the time of color change to light tan. |
I hope this information helps.
