Abstract: The study was undertaken in three ecological zones of Ondo State to determine the abundance and spatial distribution of mosquitoes in the ecological zones of the state. Twenty (20) sampling sites randomly distributed across each of the zones were sampled using aspirators, dippers and pipettes. The results revealed 12 mosquitoes species belonging to 3 genera, these include 5 species of Culex (Cx. quinquefasciatus, Cx. andersoni, Cx. duttoni, Cx. pipiens and Cx. trigripis), 4 species of Aedes (Ae. aegypti, Ae. albopictus, Ae. vittatus and Ae. palpalis) and 3 species of Anopheles (An. gambiae, An. arabiensis and An. funestus). The study further showed that Cx. quinquefasciatus was the most predominant Culex species observed in Idanre and Ese Odo, while Cx. andersoni was the predominant Culex species in Ondo, Ifon and Ikare Akoko. Ae. aegypti was the most dominant in all the locations except Ese Odo. An. gambiae has the highest occurrence in all the ecological zones. The results of this study show that the area is rich in mosquitoes, and the abundance of the mosquitoes especially the An. gambiae is of public health importance.
