Fatty aldehydes for control of major fruit pest

Tech ID: 21.675

Key Features

  • Natural volatile compounds for control of D. suzukii and other Drosophila species
  • Highly selective, benign - harmless to beneficial insects
  • Treatment prevents pre- and post-harvest infestation


Drosophila suzukii is a fruit fly originating from southeast Asia, which unlike other Drosophila species infests fruit early during the ripening stage to lay eggs under the fruit's soft skin. It is a major pest in America and Europe and is a serious economic threat for the cultivation of soft summer fruits.

Now Matthieu Louis and Ellie Fink at the Sensory Systems and Behavior Lab at the Centre de Regulació Genòmica (CRG) in Barcelona have identified medium-chain and fatty aldehydes and related derivatives, that prevent fruit infestation (egg laying) and provide protection after infestation without affecting honey bees.
