Low pea aphid survival reveals the strong insecticidal activity of crude Manica rubida venom (100% mortality) and peptide U-MYRTX-MANr1 at high (~93% mortality) and medium concentrations (~30% mortality) after 10 days. Survival (60 aphids in three biological replicates of 20 individuals per treatment) was monitored for 10 days following the injection of crude venom (A) or the peptide (B) into pea aphids, Acyrthosiphon pisum. Survival data were analyzed using Kaplan–Meier statistics and comparisons between the treatment and control were based on log-rank tests. Statistical data are shown in Table 2 and Table S2.
