Table S1. Mean viability (and standard error) for each treatment (A1–A3 and NA1–NA3 represent three different concentrations of the alkaloid and non‐alkaloid fractions, respectively; ten replicates each, see text for details). Pupal mortality was calculated as the difference between total and larval viability. Entries in bolded differed significantly from the control (P < 0.05 in Dunnett tests, see text for more details).

Table S2. Mean wing size (expressed as the logarithm of centroid size) and standard error (between parentheses) for each treatment (A1–A3 and NA1–NA3 represent three different concentrations of the alkaloid and non‐alkaloid fractions, respectively; see text for details) and sex.
