Abstract
Background
The full-scale impact of odour-baited technology on the surveillance, sampling and control of vectors of infectious diseases is partly limited by the lack of methods for the efficient and sustainable dispensing of attractants. In this study we investigated whether locally-available and commonly used textiles are efficient substrates for the release of synthetic odorant blends attracting malaria mosquitoes.
Methods
The relative efficacy of (a) polyester, (b) cotton, (c) cellulose¿+¿polyacrylate, and (d) nylon textiles as substrates for dispensing a synthetic odour blend (Ifakara blend 1(IB1)) that attracts malaria mosquitoes was evaluated in western Kenya. The study was conducted through completely randomized Latin square experimental designs under semi-field and field conditions.
Results
Traps charged with IB1-impregnated polyester, cotton and cellulose¿+¿polyacrylate materials caught significantly more female Anopheles gambiae sensu stricto (semi-field conditions) and An. gambiae sensu lato (field conditions) mosquitoes than IB1-treated nylon (P¿=¿0.001). The IB1-impregnated cellulose¿+¿polyacrylate material was the most attractive to female An. funestus mosquitoes compared to all other dispensing textile substrates (P¿
