Diagnosis overview
Cherry fruit fly makes cherries maggoty as larvae feed inside the fruit.
In gardens, Cherry fruit fly can occur on plants including Cornelian cherry, Sour cherry, sweet cherry. In the available profiles, it is linked mainly with Stone fruit.
Its importance depends on how quickly it spreads and whether seedlings, shoot tips, flowers, or fruit are affected. Ripening time, cultivar choice, and removing infested fruit are key.
Inspect leaf undersides, shoot tips, and the soil around the plant at different times of day. Eggs, larvae, droppings, webbing, or slime trails are often more diagnostic than one damaged leaf.
A common mistake is to treat feeding damage without checking the animal, eggs, larvae, time of activity, and affected plant parts.
