There are many factors that can affect the resistance of plants to pests, including the type of plant, the age of the plant, and the growing conditions. Plants can increase their resistance to pests by increasing their production of chemicals that deter or kill pests, by physical barriers that prevent pest access, or by attracting predators or parasites of the pest.
Resistance can develop when the same pesticide or similar ones with the same mode of action are used over and over again. It often is thought that pests change or mutate to become resistant. However, it is not the individual pest (insect, weed, or microorganism) that changes, but the population
Pest resistant GM crops (primarily cotton and maize), have been genetically modified so they are toxic to certain insects. They are often called Bt crops because the introduced genes were originally identified in a bacterial species called Bacillus thuringiensis.
