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.

In fruits in which PavKLUH was silenced, a decrease in fruit size was observed, due to less expansion of the mesocarp cells. By identifying a new gene encoding for PavKLUH, PavRAV2, a transcription factor capable of physically interacting with the PavKLUH promoter, was selected.

The study compares MAP and controlled atmosphere storage for Rainier, Bing, Skeena and Sweetheart sweet cherries, assessing firmness, stem quality, weight loss and postharvest disorders to identify effective strategies for maintaining fruit quality for long-term storage.

Effective sweet cherry postharvest management protects the canopy, reduces heat stress and restores tree reserves. Balanced irrigation, selective summer pruning and targeted nutrition prepare trees for dormancy while supporting bloom, fruit set and next season’s crop.
