When we speak of "pesticide resistance" we are referring to genetic changes that take place in a population (pests) over time as a result of the natural selection of individuals whose genetic make up confers some measure of immunity to the pesticide. Although the precise genetic and ecological factors differ among pests that have become resistant, in all cases resistance is driven by one process -- selection. c. broad-spectrum products. One form of resistance that can occur among resistant insect and mite pest populations is referred to as "cross resistance." Cross resistance is based on a single resistance mechanism conferring resistance to pesticides in the same chemical class and/or having similar modes of action.

Pesticides possess an inherent degree of toxicity to some living organism. Increased use of 2,4-D could have dramatic impacts on human and environmental health. in the form of insect repellents). The mix of genes in a population is called the gene pool. e. All of these. This incident echoed what had happened with DDT 50 years earlier when researchers first recorded houseflies that had resisted the pesticide. Where larval stages are being controlled, target younger larval instars where possible because these are usually much more susceptible and therefore much more eectively controlled by insecticides than older ones. The shift toward resistance leads to a gradual erosion of control. c. developing DDT and other widely used pesticides. a. have large amounts of money Reset The seeds of the plants that survived may also have this mutation because the gene was passed from the parent plant to the offspring plant.
