Worldwide invasion by Drosophila suzukii : does being the "cousin" of a model organism really help setting up biological control ? hopes, disenchantments and new perspectives

Abstract : The recent and rapid invasion of Europe and North-America by Drosophila suzukii has generated numerous laboratory and field studies since this fly species is an agricultural pest that causes economical losses by laying eggs and developing in ripening fruits, but also because of its relatedness with the model species Drosophila melanogaster whose biology and genetics are well described. This commentary is based on recent data published by different research groups as well as some of our own preliminary results. It discusses the state of research on D. suzukii and addresses the main following questions: can the wide knowledge on D. melanogaster help us to understand and manage the D. suzukii invasion and how? Are lab results on D. suzukii really informative on its biology? How can the ecological impact of an invasive species be evaluated if the ecological niche is poorly described in terms of biodiversity and trophic network? We also outline constraints for the biological control of this pest species and suggest new possible approaches for its long-term management.
