The story of insecticide resistance is again taking place with the battle against the Colorado potato beetle (CPB) in Wisconsin and the upper Midwest. This beetle has a long history of rapid development of insecticide resistance to nearly all classes of insecticides and this fact has been well documented in portions of the northeastern US and specifically Long Island, NY. It has been documented that the CPB has now developed resistance to virtually every insecticide used for its control and this includes over 40 active ingredients across several chemical classes which now, unfortunately, has begun to include the neonicotinoid class of insecticides. Potato growers rely heavily on neonicotinoid insecticides for the control of damaging populations of this insect. Although this resistance has been discrete in its distribution, it stresses the need for continued vigilance in the management of insecticide resistance and strict adherence to integrated pest management strategies which reduce the likelihood and onset of resistance development.
