Phylogeny and the evolution of host plant associations in the leaf beetle genus ophraella coleoptera chrysomelidae



Phylogeny and the evolution of host plant associations in the leaf beetle genus ophraella coleoptera chrysomelidae



Evolution 44(8): 1885-1913



Species of Ophraella, a North American genus of leaf beetles (Chrysomelidae), feed variously on eight genera in four tribes of Asteraceae. A phylogenetic analysis, based on morphological features and allozymes, was undertaken to deduce the history of host affiliation within the genus. The two data sets are combined to arrive at a provisional phylogeny of the species, onto which host associations are parsimoniously mapped. Among and within the 12 species studied, at in the same shifts are postulated to have occurred among congeneric plant species, five between genera in the same tribe, and four between different tribes of Asteraceae. The phylogeny of Ophraella appears not to be congruent with that of its hosts. This and other evidence indicates that many host shifts in Ophraella postdate the divergence of the host plants, a conclusion that may apply commonly to phytophagous insects. A phenetic analysis of the plants' secondary compounds provides modes support for the hypothesis that host shifts are facilitated by commonalities in plant chemistry. A possible trend in host shifts is evident, from chemically simpler to chemically more forbidding plants. The chemical barriers to host shifts in Ophraella appear to require adaptation in both behavior and in physiological attributes. There is no evidence that the host associations of these insects or the divergence in secondary chemistry of their hosts can be attributed to coevolution.
