Statistical analyses ran on the life history traits data obtained for P. d. dilatatus injected by wVulC (pure and diluted inoculum), wDil and control treatment.

The gain of weight and mobility were compared between treatments at 60 days post-injection with a Gaussian linear mixed-effects model with randomized block effect fitted by maximum likelihood (ML). For comparison of the P. d. dilatatus location in boxes between treatments through the whole experiment, a generalized linear model with binomial error and logit link function was performed. Survival curves were compared using a general mixed-effects Cox model with randomized block effect as for A. vulgare.
