Mechanisms of Action, Resistance and Toxicity of ...

Background: γ-Aminobutyric acid (GABA) receptors play a central role in fast inhibitory neurotransmission in insects. Several classes of insecticides targeting insect GABA-gated chloride channels have been developed. The important resistant to dieldrin GABA receptor subunit (RDL) has been used to investigate insecticide sites of action using radioligands, electrophysiology and site-directed ...

Insecticide resistance refers to changes in an insect that increase its ability to withstand or overcome the effects of one or more insecticides. When the frequency of resistant insects in a population increases (e.g. through resistance traits being passed on from one generation to another), the efficacy of an insecticidal intervention can be ...

Pesticides: Mechanisms of resistance to insecticides ...

Insects have evolved three major mechanisms to overcome toxicants; 1) biochemical resistance; 2) physiological resistance; and 3) behavioral resistance. Biochemical resistance : In this form of resistance, an insecticide is detoxified by one or more enzymes before it can reach its site of action.

Insects develop this type of resistance by expressing multiple resistance mechanisms. This can happen if one insecticide is used until insects display a resistance and then another is used and the insect population becomes resistant to that one, and so on.

Insect and mite pest populations can develop resistance to pesticides using different resistance mechanisms. The two most common mechanisms are based on metabolic and physiological resistance. Metabolic resistance involves degradation of the active ingredient by an insect or mite pest.

Mode of Action (MOA) Initiative

Resistance to insecticides was first documented by A. L. Melander in 1914 when scale insects demonstrated resistance to an inorganic insecticide. Between 1914 and 1946, 11 additional cases of resistance to inorganic insecticides were recorded.
