As a result of prolonged use of pesticides in the fields, a sharp increase in the number of pests is sometimes observed.

As a result of prolonged use of pesticides in the fields, a sharp increase in the number of pests is sometimes observed. Suggest at least three explanations for this phenomenon.

1) Due to the high concentration of pesticides, natural enemies of insect pests, predators that feed on pests, die
2) Hereditary variability (mutations) and natural selection lead to the survival of the fittest individuals who do not die from pesticides
3) Due to the high reproduction rate of insects, they transmit beneficial traits (resistance) to the next generations
4) Pests that have acquired resistance gain an advantage: in the abundance of food resources and the absence of natural enemies, they multiply and leave offspring
