Question

multiple choice question
pesticide resistance in insects has rapidly evolved because of _______.
o migration of pests from pesticide infected areas to pesticide free areas
o selection for individuals resistant to pesticides as we increase pesticide use
o the chemical composition of pesticides

Explanation:

When pesticide use is increased, individuals in the insect population that are naturally resistant to pesticides have a higher chance of survival and reproduction. Over time, this leads to the evolution of pesticide - resistant insects through the process of natural selection. Migration of pests between areas doesn't directly cause the evolution of resistance, and while the chemical composition is relevant to how pesticides work initially, it's the selection pressure from increased use that drives the rapid evolution of resistance.

Answer:

selection for individuals resistant to pesticides as we increase pesticide use
