Impact of plant secondary metabolites on the ability of the Aedes albopictus mosquito to transmit the dengue virus

The main objective of the ALBODIET project was to analyze the effects of plant secondary metabolites on the vector competence of the tiger mosquito Aedes albopictus for the dengue virus. It also aimed to describe the metabolic profiles of the dietary intake of natural populations of Ae. albopictus sampled on the island of Reunion.Réunion.

Recent years have seen a resurgence of arbovirus epidemics worldwide. While the transmission dynamics of these infectious agents by mosquito populations may be affected by variations in environmental conditions, the role of plant biodiversity as a source of nutrients for mosquitoes on one hand and secondary metabolites on the other hand in the interactions between mosquitoes and the arboviruses they transmit is not well understood. The results obtained will contribute to understanding the potential impact of plant diversity on the dynamics of arboviral transmission by mosquitoes.
