Quantities of anti-aphrodisiac compounds detected by GC-MS in accessory reproductive gland (ARG) extracts from virgin or mated Pieris rapae females. Mean (± s.d.) amount of methyl salicylate (grey columns) and indole (dark grey column) per gland is shown. Number of dissected ARG, N = 7 of each treatment. Different letters indicate significant differences in quantity within the same compound between the ARG extracts from virgin and mated females (Mann-Whitney U test). Abbreviations: ARG—accessory reproductive gland; MeSA—methyl salicylate; n.d.—not detected
