Résumé

La mise en œuvre des stratégies de contrôle intégré associant le contrôle traditionnel des Aedes avec une réduction des sources et la combination TIS-TII pour la suppression de la population sera divisée en quatre phases : 1) standardisation de la TIS-TII avec Ae. albopictus ; 2) caractérisation entomologique des populations d'Ae. albopictus dans plusieurs clusters ; 3) mise en œuvre de lâchers massifs en plein champ des mâles d'Ae. albopictus dans le cadre d'un plan LAV mené par le ministère mexicain de la Santé ; 4) évaluation de l'efficacité de l'intervention sur les indicateurs entomo-virologiques (abondance de moustiques, taux d'infection virale) avec des essais contrôlés randomisés en grappes.

The spread of Aedes mosquito vectors of pathogens that infect humans has increased due to uncontrolled/unplanned urbanization, climate change and global trade. The DENV is a major disease that causes public health issues and a global economic burden. Aedes mosquitos are the primary vectors of human disease and a major public health concern in subtropical and tropical regions worldwide. Aedes albopictus has spread from the western Pacific and Southeast Asia to Europe, Africa, the Middle East, North and South America, and the Caribbean in the last two decades. There is widespread concern among public health authorities in recently infested countries and those threatened with the introduction of Ae. albopictus which is known to be infected with at least 22 arboviruses, particularly DENV. This species was recently recorded in urban and suburban areas in the city of Merida, Yucatan. Most vector control strategies focus on the use of insecticides where insecticide resistance has increased due to indiscriminate use (intensive and extensive) of insecticides in mosquito populations. Furthermore, the use of these insecticides has been linked to environmental issues due to contamination, as well as negative effects on human health. As a result, many countries are considering WHO-recommended innovative methods. Among these innovative Aedes control methods is the incompatible insect technique (IIT), which use the intracellular bacterial endosymbiont Wolbachia. The implementation of an integrated vector management (IVM) Aedes control IIT for population suppression in Yucatan, Mexico.
