Population structure and pattern of geographic differentiation of Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) in Turkey.

Background: The Colorado potato beetle (CPB) is the most harmful pest of potato in potato cultivation regions globally. Although it is an economically important agricultural pest, the population structure and colonization route of this species in Turkey are uncertain. We used microsatellite and mitochondrial DNA (mtDNA) markers to obtain information about the population source, structure and bio-invasion route of CPB populations in Turkey.
