Resistance to fenvalerate was most extensive in potato beetle populations from Carteret and Pamlico counties, with considerable levels of resistance also present in Pasquotank and Currituck counties. Azinphosmethyl resistance was most prominent in beetle populations from Carteret and Pasquotank counties, and carbofuran resistance was most extensive in Carteret, Currituck, and Pasquotank counties. Results also showed significant levels of variation in susceptibility to these insecticides among counties, among fields within counties, and among beetle populations within fields.}, number={4}, journal={Journal of Economic Entomology}, publisher={Oxford University Press (OUP)}, author={Heim, D.
