Sujet :Participation au projet sur Xylella et ses vecteurs en Nouvelle Aquitaine et PACA
Dates :16 juin 2020 – 16 décembre 2021
Responsable CBGP :A. Cruaud & J.P. Rossi

Xavier a travaillé sur l’épidémiologie de la bactérie Xylella fastidiosa en Corse. Il a rejoint le CBGP pour 18 mois afin de participer au programme de recherche sur X. fastidiosa et ses vecteurs en régions Nouvelle Aquitaine et PACA (collaboration INRAE Biogeco, IRHS, SAVE, financement Cognac Hennessy).

Ce programme a pour objectif de mieux comprendre quelles sont les caractéristiques biotiques (composition des communautés d’insectes et de plantes) et abiotiques (configuration du paysage et climat) qui favorisent la transmission et la prolifération de la bactérie, afin d’anticiper et de limiter sa propagation. Il organisera et participera aux campagnes de terrain pour i) déterminer la composition des communautés de vecteurs potentiels et les paramètres abiotiques influençant cette composition ; ii) déterminer la phénologie et le régime alimentaire des vecteurs potentiels les plus fréquents ii) évaluer la présence /prévalence de la bactérie.

Il sera en charge des analyses statistiques des variables étudiées et participera à l’obtention des données moléculaires de caractérisation i) des réseaux d’interaction plantes – vecteurs et ii) des sous-espèces et souches de Xylella fastidiosa potentiellement présentes dans les insectes collectés. Son travail viendra alimenter la thèse de Pauline Farigoule.
