When individuals reproduce, they pass along unique combinations of genes to their offspring. Introduction to Pesticide Resistance - Pesticide Environmental Stewardship a pest population dies at normal dose for that species, ability for pest to remain uninjured by a dose normally used to control other pest species, ability of fully susceptible population to survive doses about those that were once sucessful, pest that appear in a population that exhibit resistance, population resistance to 2 or more pesticides within the same mode of action, pests resistant to 2 or more pesticides within different modes of action from different chemical families. By facilitating local persistence all year round, climate change promotes and expands pesticide resistance of the pest globally. With the help of plant breeders, fruit growers have taken advantage of the gene pool's natural variability in a process known as artificial selection. Over time many pesticides have gradually lost their effectiveness because pests have developed resistance a significant decrease in sensitivity to a pesticide, which reduces the field performance of these pesticides. Different environments favor individuals with different physical and behavioral traits.

The key is to rotate which number you use for treatments. 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.
