Porcellio dilatatus males were injected with invasive wVulC Wolbachia strain and their survival as well as their mobility was recorded on the days 60, 75, and 105 PI. A mixed effects linear model with random block effect was used to analyze mobility data. A mixed effects Cox proportional hazards model was fitted using the survival data of the lineages to estimate the effects of the treatment and the Wolbachia status. For both models, first a global model with all of the lineages (symbiotic dilatatus A-wCon, dilatatus A-wDil and asymbiotic dilatatus A) was fitted, then further analysis was made to clarify the differences between symbiotic dilatatus A-wCon and dilatatus A-wDil lineages with help of a sub-model. In bold, statistically significant values (p < 0.05).
