Abstract (English): Objective. To evaluate indoor use of commercial aerosols for dengue vector mosquito control, and estimate the number of treatable houses per can. Materials and methods. Four aerosol products containing combinations of pyrethroids (two containing propoxur and one containing synergists too), were evaluated with mosquitoes in a room of a Tapachulastyle house. Eight cages containing 20 insecticide susceptible or resistant females were hung from tripods, another set was placed in sheltered areas of the room. From the entrance of the room, one of 4-9 concentrations was sprayed for each aerosol, leaving the mosquitoes for 30 min after sprayed. Mortality was recorded after 24 h and lethal concentrations were calculated. Results. Aerosol A had the highest LC50, with 0.308 g for mosquitoes hanging from tripods and 0.453 g for sheltered mosquitoes; followed by aerosols C, D and B, with statistical differences between types of exposure. Conclusions. Aerosols B-D could spray 20-25 3-room houses (56 m3-room), killing all resistant mosquitoes. Aerosols may become a good tool for indoor mosquito control, if the optimal concentration and correct spray method are used. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Objetivo. Evaluar el uso en interiores de aerosoles comerciales para el control de mosquitos vectores de dengue, estimando el número de casas tratables por lata. Material y métodos. Se evaluaron cuatro aerosoles que contenían combinaciones de piretroides (dos propoxur y uno sinergistas también), en una habitación de casa estilo Tapachula con mosquitos dentro de jaulas. Ocho jaulas, cada una con 20 hembras susceptibles o resistentes a insecticidas, se colgaron en trípodes, junto con ocho jaulas escondidas en la habitación. Una de 4-9 concentraciones se roció desde la entrada de la habitación, dejando los mosquitos durante 30 min después del rociado; se estimaron las concentraciones letales con mortalidades después de 24 h. Resultados. El aerosol A tuvo los CL50 mayores, con 0.308 g para mosquitos de los trípodes y 0.453 g para mosquitos escondidos; seguido de aerosoles C, D y B, con diferencias estadísticas entre el tipo de exposición. Conclusiones. Los aerosoles B-D podrían rociar 20-25 casas de tres cuartos (56 m3 por cuarto), y matar a los mosquitos resistentes. Los aerosoles pueden convertirse en una herramienta para el control de mosquitos en interiores de casas, si se usa la concentración óptima y el método de rociado correcto. [ABSTRACT FROM AUTHOR]
