%X The effectiveness of implementing vector control strategies for malaria is assessed by monitoring vector dynamics and their role in malaria transmission. This study was carried out between September 2016 and August 2017 in Kintele and Djoumouna, and in August 2019 in Djoumouna alone. The objective of this study was to identify the <em>Anopheles</em> species involved in malaria transmission, their dynamics over time, and to evaluate the entomological indices based on the types of bedrooms investigated. <em>Anopheles</em> mosquitoes were collected manually from the residual fauna in the morning. Entomological indices were determined following the dissection of the Anopheles mosquitoes. Collections were performed in 541 bedrooms. The collected Anopheles species included Anopheles <em>gambiae s.l.</em> (1130), <em>Culex quinquefasciatus</em> (681), <em>Mansonia uniformis</em> (5), <em>Aedes albopictus</em> (1) and <em>Anopheles funestus</em> (1). Out of the 343 female <em>An. gambiae s.l.</em> mosquitoes whose DNA was amplified by PCR, the identified species from the <em>An. gambiae s.l.</em> complex consisted of <em>An. gambiae</em> (248), <em>An. coluzzii</em> (93), <em>An. arabiensis</em> (1) and one hybrid (1). These species were shown to be involved in malaria transmission, with higher intensity observed in sleeping rooms without Long-Lasting Insecticide Impregnated Mosquito Net (LLINs), particularly in Djoumouna. In these bedrooms, an individual received an average of 1 infectious bite every 27 days. Monitoring the status of LLINs and vectors proved to be necessary for maintaining knowledge about the effectiveness of LLINs.<br />
