Microencapsulation of a native strain of the entomopathogenic fungus Beauveria bassiana and bioinsecticide activity against pyrethroid-Rresistant triatoma infestans to vector control of Chagas disease in the Argentine Gran Chaco Region

The blood-sucking bug Triatoma infestans is the main Chagas disease vector in the Southern Cone of Latin America. Populations resistant to pyrethroid insecticides have been detected in the early 2000s and then expanded to the endemic area of northern Salta province, Argentina. In this context, the e...

Populations resistant to pyrethroid insecticides have been detected in the early 2000s and then expanded to the endemic area of northern Salta province, Argentina. In this context, the entomopathogenic fungus Beauveria bassiana has been shown to be pathogenic to pyrethroid-resistant T. infestans.
