Survival plot of C. carnea larvae reared in vitro provided with different larval preys. Preys (A. nerri, B. brassicae, A. nerri + S. cerealella eggs, B. brassicae + S. cerealella eggs and S. cerealella eggs) were evaluated for the survival of C. carnea larvae. Legends identify different food sources by different line styles. Survival difference between larval preys was detected using a Log Rank and Wilcoxon test.
