Abstract: Mosquito coils (MC) are used to prevent mosquito exposures indoors by more than two billion people worldwide. Burning mosquito coil indoors generates smoke that can control mosquitoes. The aim of this study was to evaluate novel Pyrethroid based mosquito coil (Renofluthrin 0.025% w/w) for analysis of its physical properties, active ingredient and bioefficacy against Aedes aegypti, Culex quinquefasciatus and Anopheles stephensi under laboratory conditions. The Knockdown time (KT₅₀ and KT₉₅) values of each species were evaluated after exposure of 1, 6 and 11hrs time intervals in Peet Grady chamber. Subsequently, the studies were also conducted with commercial coil containing d-trans Allethrin 0.1% w/w for comparison. The findings of the present study confirm that Renofluthrin (0.025%) mosquito coil was found to be more effective as compared to commercially available mosquito coil (d-trans Allethrin 0.1% w/w).
