International audience Since the 20th century, the sub-Antarctic islands have suffered an increasing number of biological invasions. Despite the large number of publications on this topic, there is a lack of knowledge on parasitism rates of invasive species and on the role of parasites and pathogens to regulate their populations. Six aphid species have been introduced in the archipelagos of Crozet (Ile de la Possession, 46 degrees 25' S-51 degrees 51' E) and Kerguelen (49 degrees 21' S-70 degrees 13' E). Five of these species were found infected by entomopathogenic fungi of the order Entomophthorales. All these fungal species are cosmopolitan. Conidiobolus obscurus and Entomophthora planchoniana were the most frequently observed on Ile de la Possession and in Archipel des Kerguelen, respectively.
