Figure 6. Insecticide sites of action. Some general methods of insecticide action are shown. Insecticides have many sites of action but most of those in common use affect the nervous system of the insect (B.t., Bacillus thuringiensis; DDT, dichlorodiphenyltrichloroethane; CSIs, chitin synthesis inhibitors; IGRs, interference growth regulators) (Modified from Schneider (2000)).
