Pesticide resistance
Pesticide resistance describes the decreasing effectiveness of a previously effective pesticide on pests or the increasing resistance of the pest to pesticides. Pesticide resistance usually arises through natural selection : the most resistant individuals in a pest population have the greatest reproductive success and pass on their resistance genes to the offspring. This phenomenon is homologous to the development of antibiotic resistance in disease-causing bacteria .
Even the economically desirable case, the cultivation of a resistance of crops or livestock to pesticides used widely is to be counted under pesticide resistance, such. B. in the herbicide-resistant soybean . The development of such varieties and species is a research topic in so-called green genetic engineering .
Herbicide resistance
In 2013 over 600 cases of herbicide resistance were known worldwide.
Insecticide resistance
An example of a resistant animal pest is the pollen beetle , in whose population more and more pyrethroid -insensitive individuals appear.
