Patterns of Ecological Adaptation of Aedes aegypti and Aedes albopictus and Stegomyia Indices Highlight the Potential Risk of Arbovirus Transmission in Yaoundé, the Capital City of Cameroon.

摘要: The dynamic of arbovirus vectors such as Aedes aegypti and Ae. albopictus remains poorly understood in large cities central Africa. Here, we compared the larval ecology, geographical distribution degree infestation Yaounde, capital city Cameroon, estimated their Stegomyia indices revealing a significant potential risk transmission. An entomological survey was conducted April–May 2018 cluster houses randomly selected. Each selected house inspected, number inhabitants recorded, positive containers for were characterized. pupae-based estimated. Overall, 447 954 inspected comprising 10,801 immature stages with 84.95% 15.05% aegypti. Both species bred mainly discarded tanks used tyres, associated turbid water presence plant debris inside containers. most prevalent almost all neighbourhoods. index, Breteau container index higher (38.26%, 71.81%, 29.61%) to those (25.73%, 40.93%, 16.88%). These are high thresholds established by Pan American Health Organization World Organization, which suggests
