Friend or foe? The apparent benefits of gregarine (Apicomplexa: Sporozoa) infection in the European earwig

2020

International audience; Studying the costs and benefits of host-parasite interactions is of central importance to shed light on the evolutionary drivers of host life history traits. Although gregarines (Apicomplexa: Sporozoa) are one of the most frequent parasites in the gut of invertebrates, the diversity of its potential impacts on a host remains poorly explored. In this study, we addressed this gap in knowledge by investigating the prevalence of natural infections by the gregarine Gregarina ovata and testing how these infections shape a large set of morphological, behavioural and physiological traits in the European earwig Forficula auricularia. Our results first show that G. ovata was p…
