Determination of the levels of genetic differentiation and gene flow among populations of the common bed bug, Cimex lectularius

Little is known about the levels of genetic similarity between geographically separated or adjacent populations of bed bugs. Given the existence of strains resistant to pyrethroid insecticides within the U.S., the elucidation of patterns of dispersal, colonization, extinction, and genetic structure is necessary before gene flow within and between populations, and hence the spread of insecticide resistance genes, can be understood. Such information is critical for the development of effective strategies of mitigation. In this preliminary study, sample collection was focused to three U.S. states (New Jersey [n=4], Pennsylvania [n=8], and North Carolina [n=8]). Additional single point samples were collected within New York, Washington D.C. Virginia, South Carolina, and Florida. Samples were screened for a suite of polymorphic microsatellite loci, developed specifically for this project. Results will be discussed.
