New Bioassay to Evaluate Repellency and Attractively of Chemical Products against Adults Mosquitoes Aedes albopictus and Culex quinquefasciatus - Abstract
Mosquito-borne diseases (MBD) are responsible for millions of people at riskworldwide. To control mosquito-vectors populations, an application of repellent and attractant is becoming a promising alternative but necessitates efficient bioassay methods. The purpose of this study was to estimate the efficiency of known repellents and attractants against mosquitoes Aedes albopictus and Culex quinquefasciatus(Diptera: Culicidae) using a simpler device that is comprised of a large cage (1.5m × 1m × 1m), a release cage and two bottle traps cylindrical (r=4cm, h=22cm). The whole device was placed in an experimentation room where physical conditions were noted regularly. The results showed that the bioassay is effective in measuring the targeted behavioral response. Significant sensitivities of the two species tested to low doses of compounds were observed. The method presented has many advantages including cost and reproducibility. It will allow testing new molecules in countries with limited resources.
