SusceptibilityTest Methods
One of the most important factors governing the management of insecticide/acaricide use is the availability of sound baseline data on the susceptibility of the target pest to the toxicant. Currently a wide range of bioassay and biochemical tests are employed but unfortunately the results may not be comparable since they measure different parameters which can lead to difficulties over the interpretation of monitoring data. IRAC has addressed this issue by recommending a standard range of bioassay techniques to monitor for selected pest species of economic importance.
