Why is resistance to pesticides likely to occur over time when they are used in agriculture?
What will be an ideal response?
A small fraction of large pest populations may have genes that confer some degree of immunity to a given pesticide. If very few resistant pests survive, they may reproduce quickly and create a new population of genetically resistant pests because their population is no longer balanced by the susceptible individuals. The pesticide will not be effective against this new resistant pest population.
