Spatio-temporal distribution of Aedes aegypti oviposition activity in Kano metropolis north-Western Nigeria

Abstract

Aedes aegypti are vectors of serious and debilitating arbovirus diseases that affect humans as well as domestic and wild animals worldwide. Center for Disease Control oviposition traps were used (January - December, 2019) to monitor oviposition in four sampling entities within Kano Metropolis. No oviposition activity was observed throughout the dry season with 0.00% Ovitrap Index across all locations. Oviposition activity of the mosquitoes was moderately distributed (50%) during the rainy season. Gardens had the highest oviposition activity during the rainy season (OI = 50±35%, p>0.05). Chi-square of the seasonal mean OI revealed that Aedes aegypti oviposition depends significantly (p
