Answer:
Insect become resistant to the insecticide and the soil ecosystem will lose its fertility.
Explanation:
When a particular insecticide is continuously utilized to kill an insect, during initial stages of uses, the insecticide gives expected outcome. But due to prolonged usage the insect body system may develop a resistance towards the insecticide due to which the insecticide may lose its killing ability.
On the other hand, chemical insecticide is nothing but artificially collaborated chemicals. When they are continuously used in farming, it may cause serious effects. If the same variety is used again and again it may cause biological imbalance in the soil and may lead to make the soil infertile and unfit for farming purpose.
