Aedes aegypti is the main vector of dengue fever in tropical and subtropical countries in the world. Due to the absence of a vaccine for dengue fever, the vector´s combat is fundamental fot the disease control. The spread of mosquito populations resistant to chemical insecticides shows the necessity to establish integrate vector control programs. Entomopathogenic fungi have potential for biological control of A. aegypti; however, only tow fungal species. Metarhizium anisopliae and Beauveria bassiana, have been stutied more intensely for this purpose. The present study evaluated the pathogenicity of nineteen fungal species of the Hypocreales order against A. aegypti adults, and investigated new methods for fungal application to control these mosquitoes and for detection and isolation of fungi and oomycetes from A. aegypti larvae and adults. The results clearly showed the potential of fungi, especially form the Metarhizium genus, for the combat of eggs and adult mosquitoes. The present study proposes a new pratical method for the detection and isolation of entomopathogenic fungi from infected mosquitoes collected in the field.</dcvalue><dcvalue element="description" qualifier="abstract" language="eng">Aedes aegypti is the main vector of dengue fever in tropical and subtropical countries in the world.
