What is the general mechanism for the development of pesticide resistance in insects?
What will be an ideal response?
ANSWER: Pesticide resistance is natural selection on the microevolution level. The general mechanism
is that only a few pesticide resistant individuals have to be present, or migrate into a
population, for the resistant genes to spread through a population. Since the resistant
individuals will survive and reproduce, they will soon become more common in the
population and the evolution of the resistant trait will spread quickly.
