Answer: more pesticide-resistant insects
Pesticides are the chemical or biological formulations which are sprayed upon the plants being of high economic value to kill harmful insects and disease causing organisms such as bacteria, fungi and viruses.
Pesticide resistance can be defined as the decrease in susceptibility of pests population against a pesticide. This is because of the fact that the pest species evolve pesticide resistance through natural selection. The most resistant pest against the pesticide will survive and passes the trait to their offspring. Hence, the new generation of pest species becomes resistant to pesticides.
