Abstract

The use of non-conventional insecticides and entomopathogenic fungi to control adult mosquitoes is increasing; however, the current methods are designed to evaluate the insecticidal action of the active ingredient. We describe the bioassay method to evaluate the effect of non-conventional insecticides and entomopathogenic fungi to control mosquitoes using the Potter tower. Twenty d after application, entomopathogenic fungi produced a proportion of mortality of 0.49 to 0.82, while non-conventional insecticides produced 100% mortality from 15 min after application. Our results showed that this bioassay could provide basic information on the effect of different non-conventional insecticides and entomopathogenic fungi on adult mosquitoes. Sumario El uso de insecticidas no convencionales y hongos entomopatogenos, contra mosquitos esta en aumento, sin embargo, las metodologias actuales de evaluacion estan disenadas para evaluar la capacidad insecticida del ingrediente activo. En este estudio, describimos un metodo de bioensayo para evaluar el efecto de insecticidas no convencionales y hongos entomopatogenos contra mosquitos usando la torre de Potter. Los hongos entomopatogenos a los 20 dias despues de la aplicacion produjeron una proporcion de mortalidad de 0.49 a 0.82, mientras que los insecticidas no convencionales rodujeron 100% de mortalidad desde los 15 minutos despues de la aplicacion. Nuestros resultados muestran que este ioensayo podria proveer informacion basica sobre el efecto de diferentes insecticidas no convencionales y hongos entomopatogenos sobre adultos de mosquitos.
