Survival rate among life stages
Among CJS models, the one better representing our experimental set considers treatment as the main factor affecting survival, more than individuals’ age (WAICs: ψtrat,p = 14.343, ψ,p = 15.809, ψage,p = 16.148). Also, being age less relevant than a constant condition we decided to consider stages more than age as factors affecting survival, so we applied multistate models. Multistate models considered different developmental stages as status: Larvae, Pupa and adult, plus dead stage as default. Age resulted as having an effect reducing survival probability of pupae and adult (Fig. 4A). In figure 4B we depict the three posterior distributions where pupae and adult show some variability. Considering the effect of treatment on survival in the multistate model, we obtained the mean and ranges of survival probability of the four different treatments for the three stages (Table 1). Treatment similarly affected the probability of survival compared to the control group, reporting major effects in pupal and adult stages (Figure 5).
