A new methodology to evaluate entomopathogenic fungi and formulated insecticides to control adults of Aedes aegypti (Diptera: Culicidae)
Keywords:
mosquitoes, Beauveria, botanical insecticides, bioassay, Potter towerAbstract
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 entomopatógenos, contra mosquitos está en aumento, sin embargo, las metodologías actuales de evaluación están diseñadas para evaluar la capacidad insecticida del ingrediente activo. En este estudio, describimos un método de bioensayo para evaluar el efecto de insecticidas no convencionales y hongos entomopatógenos contra mosquitos usando la torre de Potter. Los hongos entomopatógenos a los 20 días después de la aplicación produjeron una proporción de mortalidad de 0.49 a 0.82, mientras que los insecticidas no convencionales rodujeron 100% de mortalidad desde los 15 minutos después de la aplicación. Nuestros resultados muestran que este ioensayo podría proveer información básica sobre el efecto de diferentes insecticidas no convencionales y hongos entomopatógenos sobre adultos de mosquitos.
