Characterization of microsatellite loci for the western cherry fruit fly, Rhagoletis indifferens (Diptera: Tephritidae).

The western cherry fruit fly (Rhagoletis indifferens) is a major pest of cherry crops in western North America, yet relatively little is known about its population structure or movement patterns due to the difficulty of studying these parameters directly in the field. We isolated and characterized a set of 16 polymorphic microsatellite loci specific to R. indifferens that display sufficient polymorphism to assess genetic structure and movement patterns. All 16 loci amplified in one or more other Rhagoletis species, indicating that they are useful tools for genetic analysis in other members of the genus, many of which are also agricultural pests.
