Insecticides are organized into classes—organophosphates, carbamates, pyrethroids, neonicotinoids, etc.— that share a common chemical structure and mode of action (MOA). MOA is the specific process by which an insecticide kills an insect, or inhibits its growth. The target site of action is the exact location of inhibition, such as interfering with the activity of an enzyme within a metabolic pathway. MOA and target site of action are often used interchangeably in practice and are combined as MOA in this learning module.

Genetics and intensive application of insecticides are two factors of several responsible for the development of insecticide resistance. Insects with genes that confer resistance to a particular insecticide or class of insecticides survive treatment and are thereby “selected” to pass on this resistance to later generations.
