In conclusion, oil products were shown to reduce oviposition by R. cerasi, by creating a physical
barrier. However, oil deposits on the fruit surface degrade too rapidly to provide a good control of fruit
infestation. Further research is needed to assess whether the combination of oil products with different
formulants and adjuvants or higher application rates might improve field efficacy.
