Cherry fruit fly
Rhagoletis cerasi
This description was machine-translated.
How to spot it
You will see that the cherry fruit fly lays its eggs in mid May in sweet cherries that are just turning yellow; the hatched larva feeds inside the fruit and makes the cherry soft and rotting.
You will find that mainly medium to late ripening varieties are affected. Very early varieties often escape the flight. The fly recognizes the ripening colour, which is why yellow sticky traps attract it.
Prevention
You should hang yellow glue boards in the canopy from early May to detect the start of the flight, and plant early‑ripening varieties that escape egg laying. Do not loosen the soil under the tree; instead cover it during the flight period with tight mesh or fleece so that hatched flies cannot rise, and harvest promptly and completely so that no larvae enter the soil to overwinter.
