Using Genetic Markers And Population Assignment Techniques To Infer Origin Of Boll Weevils (Coleoptera: Curculionidae) Unexpectedly Captured Near An Eradication Zone In Mexico, Kyung Seok Kim, Pedro Cano-Rios, Thomas W. Sappington

Several boll weevils, Anthonomus grandis Boheman, were captured in pheromone traps in 2004 near Tlahualilo, Durango, Mexico, an area where none had been reported for ≈10 yr. It is possible that they were from an endemic population normally too low in numbers to be detected but that increased in response to more favorable rainfall conditions in 2004. Alternatively, they may represent an influx of migrants or the immediate descendents of migrants. To identify the most likely origin of the boll weevils captured in this area, we characterized microsatellite variation of the Tlahualilo weevils and compared it with the variation from ...

Molecular Genetic Variation Of Boll Weevil Populations In North America Estimated With Microsatellites: Implications For Patterns Of Dispersal, Kyung Seok Kim, Thomas W. Sappington

The boll weevil (Anthonomus grandis Boheman) is an insect pest of cotton that underwent a well-documented range expansion across the southeastern U.S. from Mexico beginning about 110 years ago. Eleven microsatellite loci were surveyed to infer the magnitude and pattern of genetic differentiation among boll weevil populations from 18 locations across eight U.S. states and northeast Mexico. Estimates of genetic diversity (allelic diversity and heterozygosity) were greater in Southern than Northern populations, and were greater in the west than the east among Northern populations. Boll weevil populations were genetically structured as a whole across the geographic range sampled ...
