In the global context of vector control, despite the successes observed with the massive use of impregnated mosquito nets and indoor insecticide treatments, the resistance of vectors to insecticides could compromise these successes. Current observations highlight the existence of behavioral heterogeneities with ethological changes in cycles of aggression or places of sting, which can increase the vulnerability of human populations and be the source of residual transmission in the sites. under anti-vector control.

The intrinsic ability of Anopheles to infect themselves from asymptomatic protors and transmit plasmodia is studied and analyzed in relation to their insecticide resistance status.

The biological, ethological and physiological behaviors of the main vectors of malaria are studied and analyzed in relation to climate and the environment to better define their vectorial capacity.

The general objective of this axis is to explore and characterize the physical, biological, genetic and environmental determinants of natural populations which govern their evolution in the face of global changes.

The maintenance mechanisms of arboviruses are investigated by studies on vertical transmission and the search for vertebrate reservoirs by identifying the origin of blood meals from collected vectors engorged in nature.

The vector competence of naturally infected mosquitoes and the factors associated with the vector or virus involved are investigated.

La dynamique du comportement éthologique et physiologique des vecteurs est étudiée dans différentes et classes écologiques puis analysée en relation avec certains paramètres climatiques.

Entomological surveillance of arbovirus circulation is carried out in Senegal in 2 sentinel sites (Kedougou and Barkedji) during the rainy season.
