The genera Thrips and Frankliniella comprise 460 species from among the 2300 species within the Thripidae (2300 spp.) and ten of these species transmit topsoviruses. It is not known why only these few species serve as virus vectors or whether the vector species within each genus are related. We aim to provide a phylogeny that better explains the species relationships within Thrips and Frankliniella. In this project our specific objectives are to determine if the vector species within each genus are related. The phylogenetic analysis includes nucleotide sequence data from two mitochondrial genes (16S and COI) and two nuclear genes (18S and 28S) from representative species of Thrips, Frankliniella and other genera of Thripidae with outgroups from Aeolothripidae, and Phlaeothripidae families.
