Comparisons of DT5, fecundity and adult weight for different Sitobion avenae clones under three treatments. DT5, (a); 10-d fecundity, (b); adult weight, (c); DT5, total duration of the nymphal stage; WW, well-watered treatment; IS, intermediate water deficit; SS, severe water deficit; data with different uppercase and lowercase letters indicate significant differences (α = 0.05, ANOVA followed by Tukey tests) among treatments for generation one and five, respectively; stars in bars indicate significant differences between generation one and five within a treatment for a particular area (*P < 0.05; **P < 0.01; ***P < 0.001)
