Attacked fruit will be pitted by oviposition punctures, around which some discoloration usually occurs. Infested fruits appear normal until the maggot is nearly full-grown, at which time sunken spots appear. Maggots and their frass inside the cherry render the fruit unsalable. Infested fruits are more susceptible to fungi. The third larval instar forms one to three holes (about 1 mm in diameter) through the skin of the cherry, before it leaves it for pupation in the soil (Frick et al., 1954).
Upon detection, fallen and infected fruit should be removed and destroyed. This aspect is very important, but normally rarely executed as it costs time and money.
Due to the variable regulations around (de-)registration of pesticides, we are for the moment not including any specific chemical control recommendations. For further information, we recommend you visit the following resources:
R. cingulata is an important pest of cherries in eastern North America. In Europe, where it is found in cherry growing regions, it attacks late cherry varities, often tart cherries.
