New protection strategies for the carrot fly (Psila rosae Fab., Diptera, Psilidae) in France


Abstract: The carrot fly (Psila rosae Fab.) is a major pest of carrot crops in France and throughout Northern Europe. There can be three generations per year in the climatic conditions of France. This pest is taking on new importance with the reduction in the number of active ingredients now available for crop protection due to the withdrawal of organophosphates and carbamates: currently, only pyrethrins are available. Hence the need to initiate research into new means of both chemical and alternative control.In the first stage of the trials, encouraging results were obtained with several new active ingredients. However, it is necessary to initiate new protection strategies, based on various methods of supervised control and various active ingredients.
