In simple terms, individual susceptibility to insecticides varies within insect populations, and selection pressure caused by utilizing these products allows less susceptible individuals (carrying resistance genes) to survive and pass the resistance trait on to their offspring. (irac-online.org)
Establishing baseline susceptibility involves measuring the initial variability in sensitivity of a given insect population to an a.i. or determining the field performance of an a.i. prior to large scale exposure of target insect field populations (i.e., commercialization in major crop production areas). (irac-online.org)
After baseline establishment, the susceptibility of field populations is systematically monitored using methods in line with those used for establishing the baseline and or insecticide performance (i.e., efficacy) is evaluated over time in regions of high use to identify deviations from the baseline.
