Resumo
The replacement of native plants by introduced or invasive exotic plants may have significant impacts on the fauna of herbivorous insects. These impacts can occur both directly, through changes in reproductive success and population size herbivorous insects that consume the exotic plants, and indirectly through changes in the availability of native host plants. This study is divided into two parts. In the first chapter, I evaluated the effect of phylogenetic isolation on the richness and composition of species of herbivorous insects on exotic plants. In addition, I also examined possible differences in response to phylogenetic isolation of exotic plants between herbivore assemblages made up exclusively of endophagous and exophagous insects.In the second chapter, I evaluated the effect of phylogenetic isolation of host plants on the mean specialization of herbivorous insects fauna associated with host plants. In addition,I also analyzed the effect of phylogenetic isolation of host plants differs between native and exotic plants. Taken together, the results of the two chapters exemplify how the richness, composition and specialization of herbivores respond to phylogenetic isolation of their host plants.
