Since its arrival in France in 2010, Drosophila suzukii has caused extensive damage to several species, including cherries. Its biological characteristics (short development cycle and high number of eggs per female) make it a highly damaging pest.
It is essential that growers develop strategies to combat D. suzukii in every plot in order to minimise production losses.
The purpose of this CTIFL note is to provide technical elements to be taken into account for phytosanitary protection of cherry trees against D. suzukii.
All information in this note is up to 3 May 2023.

A recent study from Poland analyzed the effects of sublethal doses of acetamiprid and nicotine on Drosophila suzukii, evaluating alterations in wing symmetry among exposed insects. The parameter used for evaluation was the "fluctuating asymmetry".

A Chinese study shows how endophytic fungus S16 enhances drought tolerance in sweet cherry trees grafted on Gisela 5 by activating antioxidant defenses, protective metabolic pathways and improving root microbiome. A promising agronomic innovation.

A recent Serbian study tested 14 cherry rootstocks on heavy, acidic soils without irrigation. Results show how each rootstock impacts fruit size, sugars, acidity and antioxidants, helping farmers make better rootstock-cultivar choices for quality yield.

In 2025, the CTIFL research center in La Tapy (France) evaluated 20 cherry varieties, focusing on fruit size, productivity, firmness, and resistance to cracking. Researcher Aliénor Royer-Lanoote presented key data to guide cherry orchard planning across European growing regions.
