Chemogenetic characterization of the egg-laying behavior of the fruit pest species Drosophila suzukii – Chemosuz

Submission summary

Drosophila suzukii is an invasive species causing severe damages to the fruit industry in Europe and North America. Indeed, in contrast with other drosophilids that exclusively target decaying fruit, D. suzukii has evolved a preference for laying eggs in ripening fruit, precipitating their decay. D. suzukii is one of the most important pest insect in Europe, that target a broad range of fruit species, and for which we have no efficient control strategies. We have previously established that the egg laying on ripening fruits is mediated by olfactory cues.
The goals of this project are (1) determining which fruit odors elicit egg laying in D. suzukii, (2) identifying the Olfactory Receptors sensing these odors, and (3) identifying novel ligands for these receptors that can be used in integrated pest management strategies.
To achieve these goals we will combine analytical chemistry, computational modeling, and neurogenetics and genome editing technics that we have developed for D. suzukii.
