Modélisation de l'environnement d'un moustique vecteur de maladies : l'exemple d'Aedes aegypti à Delhi (Inde) et Bangkok (Thaïlande)

Abstract : Aedes aegypti is the main vector of dengue and Zika virus. Surveillance and vector control are frontline weapons in the battle against arboviruses transmitted by this mosquito. In this framework, the following thesis introduces a conceptual model (MODE) which can be used to recreate in silico the dynamical environment of Aedes aegypti at scales that match the ones at which vector control campaigns are organised (city scale - MODE-macro) and performed (neighbourhood scale - MODE-micro). The environment thus generated can be integrated with an agent-based model to simulate dengue or Zika complex pathogenic systems (environment - vector - host - virus) and can be used to map the environmental hazard of the vectorial risk in a city. The conceptual model MODE is based on a phenomenological approach that is transferable in time and space : it can be applied in different urban contexts, at different periods of time and at different scales. In order to ensure their spatio-temporal genericity, the computer models MODE-micro (neighbourhood scale) and MODE-macro (city scale) have been implemented for the purpose of generating dynamical environments using open or easily accessible data. In this thesis, MODE's potentials were assessed in Delhi (India), and Bangkok (Thailand).Knowledge resulting from the study of the dynamic, multifactorial and non-linear relationships between the environment and the vector should lead to the improvement of vector surveillance and control strategies.
