Survival curves of L2 larvae fed on potato leaf discs treated with 0.2 g/L ledprona (dsPSMB5), 0.2 g/L of the non-target control (dsGFP) or water (n = 60) for 10 days. Ledprona-treated CPB larvae demonstrated a significantly lower probability of survival than the control groups. Survival was plotted using Kaplan–Meier statistics and significance was determined using the log-rank Mantel–Cox test (****p < 0.0001). Days where significance begins are marked with asterisks (*). Error bars denote standard errors of the mean.
