Classification Of Insecticides

Synthetic organic insecticides may be divided into several major classes: (1) chlorinated hydrocarbons, (2) organophosphorus compounds (often referred to as organophosphates), (3) carbamates, (4) pyrethroids, (5) nicotinoids, (6) fumi-gants, (7) GABA receptor antagonists, (8) chitin synthesis inhibitors (benzoylureas), (9) mitochondrial poisons, and (10) insect hormone mimics. These classifications are based on either group-specific chemical characteristics (classes 1—6) or their action mechanisms (classes 7—10).

Other insecticides belonging to minor classes (i.e., fewer compounds per class or less frequent use) are (11) botanically derived naturally occurring insecticides (other than pyrethroids and nicotinoids), (12) microbially produced insecticides, (13) synergists, (14) semiochemicals such as attractants, including pheromones, (15) insect repellents or feeding deterrents, and (16) behavior-modifying agents for use on insects.
