'Natural selection' can be defined as the process of selection of the organisms who are more evolved and better suited for their surroundings and are capable of producing high number of offsprings. Artificial selection can be defined as the selection of the organisms by the humans to selectively breed whether or not they are suited for the changing surroundings or not. Since, the farmer only introduced the pesticide, and the insects evolved and inherited resistance to the pesticide, this is a case of the natural selection.
