Abstract:
This study assessed the influence of bed nets and insecticide application on
distribution of Culicine mosquito in urban center of Lavun Local Government of Niger
State. Mosquito borne disease has resulted for about 627,000 deaths in the world
602,000 in African and 199,689 in Nigeria, according to world malaria report by World
Health Organization (2021). Adult mosquitoes were collected indoors using pyrethrum
spray catch (PSC). They were identified morphologically into species and categorized
according to their physiological status, using standard identification keys. Two
Culicines species were recorded, which are Culex quinquefasciatus and Culex pipiens
pipiens in Kutigi Metropolis during the study period. Temperature and relative
humidity played an important significant role in Culicine species abundance that is, it
influenced their number negatively in Kutigi Metropolis (-0.78893 and -0.28089
respectively). Furthermore, Culicine species correlated positively with open, semi close
and close eave types, but between close eave were not significant (r = 0.50341, 0.59705
and 0.27974 respectively) during the study period. The study further recommends
prevalence of Culicine born disease in the subject population living in the locality and
there is a need for more studies on species distribution and abundance of the same
species season-wise to see if their distribution will follow the same pattern year-round.
