Abstract
Waste automobile tyres are suitable receptacles of rainwater thus capable of supporting the breeding of vector mosquito species in close proximity to humans and altering disease transmission risks. Bionomics of mosquitoes in carelessly discarded tyres was explored to unravel species composition and abundance, physicochemical parameters of microhabitats and epidemiological significance. Of the 1179 larvae isolated from 90/212(42.45%) positive tyres were ten species belonging to Aedes and Culex genera, including Aedes aegypti (46.56%), Culex albiventris (0.25%), Cx. cinereus (0.25%), Cx. grahami (0.68%), Cx. ingrami (1.44%), Cx. nebulosus (2.37%), Cx. mirificus (0.08%), Cx. pipiens pipiens (0.17%), Cx. quinquefasciatus (47.07%) and Cx. tigripes (1.10%). Abundance of the dominant Ae. aegypti and Cx. quinquefasciatus did not differ significantly ( P > 0.05), but was higher than those of the other eight species (P < 0.05). The microhabitat pH (range 5.20-9.50), total dissolved solids (range 15-802ppm) and electrical conductivity (range 30-1603μscm- 1) were obtained in tyres. Abundance of Cx. quinquefasciatus correlated positively and significantly with EC and TDS of breeding water (P < 0.05). The study revealed high potential of the transmission of filariasis and arboviruses including dengue and yellow fever by mosquitoes domiciled in waste tyres.
