In recent years, increased deforestation and replacement of areas intended for intensive cultivation have caused pathogens and parasites of Apis mellifera bees to emerge in regions where they had not previously been reported.

In northern Argentina, few studies have focused on this important entomopathogen. This is the first study on A. apis isolated from commercial pollen in Entre Ríos, Jujuy, and Misiones provinces, where its prevalence in bee colonies has not been reported.
