How does an insect species become resistant to an insecticide?
the more exposure an insect has to the insecticide the weaker the effects of it are.
after an exposure if the insect survives, it mutates to become resistant if it encounters it again.
there are some offspring already resistant to the insecticide's effects that survive and reproduce.
after exposure, all the reproductive cells have mutated to become resistant for the next generation.
