In the question below choose the word(s) or phrase(s) which best fills(s) the gap(s):
Insects can become _____ to insecticides
Answer Details
The word that best fits the blank is "resistant." Insects can become resistant to insecticides over time due to natural selection. When an insecticide is used, it kills the susceptible insects, but a small number of insects may have a genetic mutation that makes them resistant to the insecticide. These resistant insects survive and reproduce, passing on the resistance gene to their offspring. Over time, the resistant population becomes dominant, and the insecticide becomes less effective. This is why it is important to use insecticides responsibly and in combination with other pest management strategies to prevent the development of insecticide resistance.
