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).
