Abstract: Oviposition choice is a well-studied aspect of mosquito life cycle and effects a potential venue for species-specific surveillance and control. In the absence of standardized controlled release lures of known composition, infusions remained the most practical means for baiting gravid female traps. This technique has been further improved by adding plant leaf infusions in different strengths to enhance its attractiveness to ovipositing mosquitoes. In the present study, the ovipositional rate of Aedes aegypti in ovitraps treated with infusion of Azadirachta indica, Hevea brasiliensis and Ocimum tenuiflorum leaves was assessed. The results revealed that in all the three plant infusions, there was reduction in the number of eggs laid as the concentration increased and the average number of eggs laid in ovitraps with leaf infusions of Azadirachta indica, Hevea brasiliensis and Ocimum tenuiflorum at concentrations of 30, 50 and 100% were 76.2 ±6.02, 43.6 ±9.09 and 17.8 ±3.97; 80.2 ±8.46, 42.0 ±9.33 and 17.6 ±2.86; 62.0 ±2.81, 49.4 ±2.42 and 21.8 ±4.08 respectively. The present study demonstrated the potential of leaf infusions in stimulating oviposition by mosquitoes in ovitraps. Moreover, leaf infusions represent a new alternative for use in oviposition traps and may expand its usage in homes and consequently assist in the monitoring and management of Aedes aegypti population.
