Please click here to see any active alerts. Mechanisms of Resistance to Insecticides There are two very important and widespread mechanisms of resistance that have been uncovered by insect toxicology researchers: (1) enhanced rates or pathways of detoxification by the insect, and (2) altered target site. This can happen if one insecticide is used until insects display a resistance and then another is used and the insect population becomes resistant to that one, and so on. Pest Management Providers: Register Today! How Pesticide Resistance Develops - Grapes The use can be intermittent.
