First records of aphid-pathogenic Entomophthorales in the sub-Antarctic archipelagos of Crozet and Kerguelen
Since the 20th century, the sub-Antarctic islands have suffered an increasing number of biological invasions.

Five of these species were found infected by entomopathogenic fungi of the order Entomophthorales. All these fungal species are cosmopolitan.
