Pollinator-dependent, pollen-rich plants may face a trade-off between the repellence of pollen-feeders and attraction of pollen-dispersers. Common tansy (Tanacetum vulgare, Asteraceae) forms chemotypes with characteristic patters of terpenes in leaves and flowers, which are differentially frequented by herbivores. In this project the relationship of chemotypes and pollination as well as changes in terpene composition after successful pollination or presence of florivores are investigated.
