Recent studies have observed vectors resting predominantly outdoors in settings where anti-vector tools are extensively deployed. This has been attributed to selection pressure from use of control tools. This present study examined if the outdoor resting behaviour in the vector population is random or indicative of a consistent preference of one resting site over the other. Mark-release-recapture experiments were conducted with outdoor-resting and mosquitoes collected from two villages in northern Ghana during rainy and dry seasons. Mosquitoes were marked with fluorescent dyes and released indoors. The experiments were controlled with indoor-resting mosquitoes, which were marked and released outdoors. Twelves release events were conducted for outdoor-resting mosquitoes and two for indoor mosquitoes, with ten replicates in each event. Species of all recaptured mosquitoes were identified and assessed for consistency in their resting behaviour. A total of 4,460 outdoor-resting mosquitoes comprising .) (2,636, 59%) and complex (1,824, 41%) were marked and released. Overall, 31 (0.7%) mosquitoes were recaptured mostly from outdoor location comprising 25 (81%) and 6 (19%) complex. Only 3 (10%) of the recaptured mosquitoes were found resting indoors where they were released. The majority of the outdoor-recaptured mosquitoes were (11, 39%), followed by (7, 25%); whereas all indoor-recaptured mosquitoes were . For the control experiment, 324 indoor-resting mosquitoes constituting 313 (97%) and 11 (3%) complex were marked and released. However, none of these was recaptured neither indoors nor outdoors. More mosquitoes were captured and recaptured during rainy season, but this was not statistically significant (Z=0.79, P=0.21). These results suggested the tendency for the mosquitoes to retain their outdoor-resting behaviour. Further investigations are required to ascertain if emerging preference for outdoor resting behaviour in malaria vector populations is consistent or a random occurrence.
