Different letters within a column indicate significant differences at α = 0.05: Tukey contrast test (ovipositing females and egg hatch), Kruskal Wallis test (preoviposition period), Tukey test (oviposition period, fecundity, adult longevity).
a The number of adult pairs tested at each temperature is placed in parentheses.
b ANOVA run after using Box–Cox transformation, λ = 0.1.
c Based on the total number of eggs laid per treatment.
d ANOVA run after using Box–Cox transformation, λ = − 0.3.
e ANOVA run after using Box–Cox transformation, λ = − 0.1.
