ETUDE DE LA NUISANCE DES MOUSTIQUES EN MILIEU UNIVERSITAIRE DE LA FACULTE DES SCIENCES ET TECHNIQUES, BAMAKO, MALI

Mosquitoes are potentially harmful and vectors of pathogens. They compromise the rest and well-being of humans and animals. The main goal of this study is to determine the composition of mosquitoes responsible of human biting at the Faculty of Sciences and Technics of Bamako-Mali. Longitudinal monitoring with monthly cross-sectional visit was carried out from September to December 2019, in order to collect the endophilic and endophagic mosquitoes. The spray-catch was used as a collection methodin 21 rooms selected randomly at the FST. Mosquitoes were identified morphologically andthen by PCR. ELISA-CSP test was used for Plasmodium infection index and the ELISA blood-meal test was to determine mosquitoes blood origin. In total, 802 mosquitoes were collected: 794Culex and 8Anopheles. There were 200 males and 602 females. Female mosquitoes were separated by gonotrophic stages: 231 unfed, 223 fed, 80 semi-gravid and 68 gravid. Up to 34% of Culex and 67% of Anopheles had a preference for human blood, but no female tested positive for Plasmodium infection. This result would be due to the small number of Anopheles captured. An. coluzzii is the only Anopheles species collected.This study shows that mosquitoes are linked to serious problems of nuisance and risk of pathogens transmission in the university. They highly prefer to feed on human host.
