Evolution of feeding preference in a leaf beetle: the importance of phenotypic plasticity of a host plant.

摘要: Much attention has been paid to ecology and evolution of damage-induced plant responses. Recently, it emphasized that phenotypic plasticity, such as induced responses, the potential lead evolutionary changes interacting partners. Here, we report regrowth promotes a locally adaptive feeding preference leaf beetle, Plagiodera versicolora. We found there was among-population variation in strength beetle for leaf-age types conspecific host plants. The positively correlated production plants across populations, intensity likely have responsible geographic new production. Within one population, detected significant additive genetic variance heritability consuming vs. old leaves. Moreover, significantly related egg depending on types. Thus, allopatric populations can evolutionarily develop different preference, according distinct patterns regrowth.
