Probably insects developed resistance to the pesticide.

Step-by-step explanation:

The term resistance refers to an inheritable change in the population sensitivity,. In the exposed example, the first time that the farmer sprayed the pesticide, the insect population decrease sharply. This means that the chemical affected them severely. They probably passed this modification to the following generations, which expressed it, and developed resistance to the pesticide.

Answer:

The pesticides are worn off by the weather.

Step-by-step explanation:

Becuase the chemicals can only work for a little in the pesticides so when bad weather comes around it finishes the rest of the chemicals in the pesticide.

Hope this Helps :)
