Resistance - Ackerman Lab

Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase. Bt is a form of natural pesticide, as with any kind of pesticide

PUBLICATION Insecticide and Miticide Resistance Management

resistance is the most common mechanism of resistance. The insect uses various enzymes to detoxify (destroy) the pesticide before the poison can kill the insect. Many insects use esterase or mixed-function oxidase enzymes to break down pesti-cides. These enzymes are already in the insect, and resistant insects produce more of

Pesticide resistance in field populations of stored-product insects can be determined by exposing insects to a series of doses of a residual insecticide and recording the mortality of insects at each dose. Offspring of field-collected insects may need to be reared in the laboratory to have enough insects for the dose-mortality test.
