Insects pollinating parsnip Pastinaca sativa l. (Apiaceae) in Moscow province

Abstract

The purpose of the study was to test the ability of Pastinaca sativa , as one of the plants whose sap contains furanocoumarins, to attract the same types of insects as the most dangerous weed - Sosnowsky’s hogweed, which is widely spread in Russia. As a result, 46 species of pollinating insects from the orders Hymenoptera (3 species), Hemiptera (2 species), Coleoptera (10 species) and Diptera (31 species) have been recorded on P. sativa . Among the latter, representatives of Tachinidae (6 species), Anthomyiidae (6 species), Calliphoridae (4 species), and Syrphidae (4 species) predominated. About 50% of insects pollinating P. sativa are found on other species of umbrella plants, including native species Anthriscus sylvestris , Aegopodium podagraria , Angelica sylvestris ; on horticultural crops: Anethum graveolens , Petroselinum crispum , Carum carvi , Coriandrum sativum , Levisticum o cinale , and on the invasive hogweed Heracleum sosnowskyi . It was not possible to detect any preference of insects for yellow (parsnip, lovage, dill) or white (kupyr, goutweed, angelica, hogweed, parsley, cumin, coriander) corolla color, plant height (from 30 cm to 2 m) or umbrella diameter (from 8 to 30 cm). Among all the captured insects, the following groups can be distinguished: those found on P. sativa and on wild-growing species of Apiaceae - 6 species; on P. sativa and garden crops - 4 species; on P. sativa and Heracleum sosnowskyi - 4 species; found on many species of Apiaceae - 10 species; found only on P. sativa - 24 species.
