Étude des déterminants génétiques, physiologiques et environnementaux des rythmes journaliers d’activité chez les anophèles vecteurs du Plasmodium

Abstract : The appearance of new patterns in Anopheles biting behavior following the universal coverage of LLINs is worrying for malaria control. Indeed, the meticulous selection of vector populations that are able to escape the physical-chemical barrier of LLINs and bite when people are not protected is still ongoing. It is known that many Anopheles life rhythms are governed by an endogenous clock known as circadian which allows their temporal organization. In addition, several biotic (physiological resistance, nutritional status, parasitism, competition) or abiotic (light-dark cycle, temperature) environmental stimuli can modulate the insects’ behavioral rhythms. As part of a better understanding of the shifted aggressive behavior observed in the field among malaria vector, and the determinants that may be involved, we have undertaken experimental studies on the daily rhythm flight activity of population of vectors that are involved in the transmission of malaria in Burkina Faso.
