Abstract
Eighteen leaf flavonoid compounds were isolated from several populations of Rhus tripartita from xeric habitats in Israel, ornamental Schinus terebinthifolius from Israel, and three species of Rhus (vulgaris, natalensis, tenuinervis) from mesic habitats in Kenya. Foodplant preference testing of Rhus-feeding Leaf Beetles (Blepharida sacra from Israel and B. marginalis and B. conradsi from Kenya) correlated well with the flavonoid composition of the different foodplants. Blepharida sacra and B. marginalis foodplant preferences demonstrated an herbivore sibling relationship but there is evidence, including foodplant ecology and distribution, that they are separate species. The herbivorefoodplant coevolution of the xeric B. sacra-R. tripartita is distinct from that of the mesic B. marginalis-R. vulgaris/natalensis, however, this study also indicates possible ancestral relationships between the herbivore species as well as between the plant species.Keywords
