Host specificity of wood-boring beetles (Cerambycidae) in lowland rainforests

This is a study of species richness and host specificity of cerambycid larvae (Cerambycidae) developing in wood of rainforest trees. Baits of freshly cut wood from are exposed in the forest canopy and understorey to allow oviposition by cerambycids, then placed in cages and regularly checked for emerging cerambycids. We surveyed 30 species of trees from various phylogenetic lineages and reared 4,000 cerambycid beetles from 55 species and documented low host specificity of most of the species. . The study is being expanded in two directions: (i) we continue rearing cerambycids from all species of trees with trunk diamter >10 cm found in a 1 ha of a primary lowland rainforest in New Guinea, and (ii) we replicate the host specificity study in lowland forests of Panama, Central Europe, Borneo, and Fiji.
