Taxonomic isolation and the accumulation of herbivorous insects: a comparison of introduced and native trees

Abstract

Abstract. Evidence from leaf‐mining insects on Fagaceous hosts suggests that range expansions of insects onto introduced trees often involve species that feed on native hosts closely related to the introduced host. An examination of the herbivorous entomofauna of British trees illustrates that the size of the entomofauna is partially determined by the taxonomic isolation of the host tree.
