Entomological analysis reveals distinct malaria vector profiles and biting patterns in Cameroon, highlighting intervention needs.

To evaluate the biting behavior and vector composition of malaria mosquitoes in two ecological settings in Cameroon.
Conducted Human Landing Catches (HLCs) to collect adult mosquitoes indoors and outdoors.
Morphological identification of collected mosquitoes.
Dissection of a subset of mosquitoes to assess parity status.
Molecular analysis using DNA from sampled mosquitoes to identify species and Plasmodium infection.
Estimated Entomological Inoculation Rate (EIR) based on Plasmodium infection rates.
Total of 3,651 Anopheles mosquitoes collected, with significant variations in species composition between Mfou and Tibati.
An. gambiae s.s. predominated in Mfou, while An. funestus s.s. was the major vector in Tibati.
Host-seeking activity peaked outdoors in morning hours, with no significant differences between indoor and outdoor catches.
EIR was notably higher in Mfou (1.47 ib/p/n) compared to Tibati (0.25 ib/p/n), suggesting higher transmission potential.

Bouopda-Tuedom et al. (2026) studied this question.
