Maximum densities of colonizing adults ranged from 0 to 14,891/ha and maximum egg mass densities ranged from 0 to 48,451/ha. Crop rotation generally resulted in lower potato beetle populations. Regardless of crop rotation management practices, colonization of fields planted in potatoes began at field edges and progressed inward in all fields for both years. Management of potato beetles is discussed in light of these findings.}, number={3}, journal={Entomologia Experimentalis et Applicata}, publisher={Wiley}, author={French, N.

Mean bioassay mortalities were subjected to correlation analysis to assess patterns of resistance among tested insecticides. Within insecticide classes, cross‐resistance patterns were observed between carbaryl and carbofuran (carbamates), fenvalerate and permethrin (pyrethroids), and among azinphosmethyl, methamidophos, and phosmet (organophosphates). Significant associations between insecticides from different insecticide classes were concluded to be due to multiple resistance. Knowledge of multiple and cross‐resistance patterns are discussed in relation to the bioassay as a tool for monitoring insecticide resistance.}, number={2}, journal={PESTICIDE SCIENCE}, author={FRENCH, NM and HEIM, DC and KENNEDY, GG}, year={1992}, pages={95–100} }
