The ambrosia beetles, Xyleborini, currently include 45 genera and approximately 1300 species which are distributed throughout worldwide forests with most diversity located in the tropics. They also represent the most invasive scolytines in North America. Despite economic concerns and biological curiosity with this group, a comprehensive understanding of generic evolutionary relationships is poorly known. Also, the biological factors contributing to their great diversity have been little explored. In this study, we generate DNA sequences for nearly complete mitochondrial genomes and for nine nuclear genes for 43/45 genera. Bayesian analysis resulted in improve phylogenetic resolution as compared to previous phylogenies. Evolutionary trends of body size and associated biological factors will be analyzed. Results are to be determined.
