The objective of this project is to decipher the adaptive changes observed at various traits that occurred during the invasion of the harlequin ladybird (Harmonia axyridis), through the close integration of population genomics with experimental studies.
To this aim, we have produced a large amount of H. axyridis genomic ressources (including de novo genome sequencing and transcriptomic data), and we are developing a BAC library in collaboration with CNRGV to allow local detailed genomic investigations.
We are presently screening the H. axyridis BAC library with some candidate probes associated to a first trait of interest, color polymorphism.
