insecticide resistance

the ability of a member of an insect population to withstand the toxic effects of an insecticide to the point that it now resists control with that chemical. The genes controlling resistance are thought to be present in low frequencies within a generally susceptible population before application of the chemical. After treatment, susceptible members of the population are removed and the survivors thrive, becoming common in the population which is then described as ‘resistant’.


an agent that kills insects. May be applied by pour-on technique, dipping, spraydip, jetting, dusting powders. Insecticides come in a wide variety of chemical compounds. See also pyrethroids, rotenone, derris, chlorinated hydrocarbons, organophosphorus compound, arsenical, carbamates, triazines. The toxicity of an insecticidal preparation may be greatly altered by the agents used as emulsifiers and solvents. Called also pesticide.

insecticide resistance
insects exposed to one insecticide for long periods may develop a resistance to it and suffer no ill-effects when it is applied.
