.Oviposition stimulants from the foliage of wild parsnip, Pastinaca sativa (Apiaceae), were isolated by column chromatography and HPLC and tested in bioassay experiments with hand‐held female black swallowtail butterflies, Papilio polyxenes (Lepidoptera: Papilionidae). Two of the stimulants were identified as tyramine and trans ‐chlorogenic acid. A combination of tyramine, trans ‐chlorogenic acid and an active neutral fraction was needed to elicit a significant oviposition response. These results are discussed in the context of previous research on the oviposition stimulants of swallowtail butterflies and on the significance of tyramine as a neuromodulator of physiological processes in invertebrates.
