Illustration of IPM program. Economic Injury Level (EIL) = lowest population density that will cause economic damage. Economic Threshold (ET) = population density at which control measures should be determined to prevent an increasing pest population from reaching the EIL. The arrow indicates the point where pest levels exceeded the ET and an IPM strategy would be applied.
