From: Biological parameters of two syrphid fly species Ischiodon scutellaris (Fabricius) and Episyrphus balteatus (DeGeer) and their predatory potential on wheat aphid Schizaphis graminum (Rondani) at different temperatures

Fig. 1

Relative fitness of I. scutellaris and E. balteatus, under different temperature regimes, expressed in terms of egg incubation period (a) and pupation period (b). The data points presented are means ± SEM. Different lowercase letters above each line demonstrate a significant difference among each data point, while an asterisk above a pair of data points presents a significant difference among two predator species (P < 0.05)
