title: The evolutionary history of maternal plant-manipulation and larval feeding behaviours in attelabid weevils (Coleoptera; Curculionoidea).
abstract: Attelabid weevils manipulate specific structures of their host plants in a species-specific manner, e.g., cutting a shoot, cutting a leaf, rolling a leaf, or constructing sophisticated wrapped leaf rolls, presumably to secure the survivorship of eggs or larvae. To depict the evolutionary history of maternal plant-manipulation behaviours and larval feeding strategies of the family Attelabidae, molecular phylogenetic analyses were conducted by sequencing the nuclear 18S and 28S ribosomal DNA and the mitochondrial cytochrome oxidase subunit I genes. Our analyses indicated that the attelabid weevils form a monophyletic group, and that maternal plant-cutting behaviour originated in a common ancestor of Attelabidae, but was subsequently lost in several lineages. Monophyly of the subfamily Attelabinae was also recovered with high support, but the subfamily Rhynchitinae was not recovered as monophyletic. By employing maximum-likelihood-based ancestral state reconstructions, larval leaf-blade feeding was inferred to have evolved from boring of cut shoots/petioles. Moreover, maternal leaf-rolling behaviours likely originated independently in the Attelabinae and Byctiscini lineages, and in several Deporaini lineages. As the sophisticated behaviours constructing wrapped leaf rolls of Attelabinae originated only once and has not been lost from the lineage, these complex and innovative behaviours may have contributed to the success and diversification of the lineage.
