Boll weevil re-infestation demography: A case study

In the US, the boll weevil, Anthonomus grandis grandis Boheman, is a pest of commercial cotton, but has been eradicated from most of its range. However, populations in the Lower Rio Grande Valley, TX and Mexico continue to threaten eradicated areas. When weevils are captured in an eradicated area, eradication programs need information that can give insight on how the re-introduction was initiated, such as the captured weevils source population and demographic information to make informed decisions about management and remedial action. Previous work developed a pipeline to determine origin population using SNP markers, but other demographic information is lacking. In this study, low-coverage, whole-genome sequence data was used to calculate relatedness from trap-captured boll weevils from a re-introduction event in an eradicated area near Kingsville, TX.
