Many species in the beetle family Cerambycidae are serious pests of trees in forests, plantations, and ornamental settings. Because the larva develop in the woody tissues of host trees, chemical control is often difficult. Natural enemies, particularly parasitoids, can be important natural enemies of wood boring beetles, and so have great potential as biological control agents. Exploitation of parasitoids to manage cerambycid pests, however, is complicated by the poor state of the literature on host associations. We will present an analysis of phylogenetic relationships among parasitoid species that are associated with the Cerambycidae that is derived from the world literature.
