Assessment of Indoor and Outdoor Resting Adult Female Mosquitoes Density Exhibiting Vectorial Portent, Insight from Kano State, Nigeria

Mosquito proliferation has been on the increase in most communities of Kano State, leading to a high rate of mosquito-borne diseases, pregnant women, and infant mortality. Mosquitoes spend the daytime resting in human dwellings, frequent survey of these mosquitoes is needed in vector control for breaking disease transmission. Despite this, data on mosquitos’ density are frequently missing. In this study, we have collected and identified all samples of indoor and outdoor resting mosquito species to assess female density. A longitudinal survey was carried out in three different sentinel sites (Darmanawa, Wudil, and Baba Ruga) for the period of 6 months (August 2023 to March 2024). Indoor mosquitoes were collected using the pyrethrum spray Method, while the outdoor mosquitoes were collected using a cardboard box. The knockdown mosquitoes were transported to the laboratory for identification, using a digital LCD microscope to gender and species level with the aid of different taxonomic guides. A total of one thousand and five (1005) female mosquitoes belonging to 5 genera and 21 species were caught. The result showed a significant influence (p 0.05). We concluded that adult female mosquitos’ density is affected by species, months of the year, resting behavior, and season, as well as the high density of An. gambiae and Cx. quinnquefasciatus recorded is a bio-portent of malaria and filariasis spotlight in these communities.
