Question

The phenomenon of using a predator for controlling a pest is
A. Biological control
B. Genetic engineering
C. Artificial control
D. Confusion technique

Answer 1

Hint: Pest control is the management of pests which is a microorganism and can affect adversely on the activities of humans. The pest is also included in the animal kingdom.

Complete step-by-step answer:
Let's discuss the above options and find the correct answer:
- Biological control: It is a method to control the pest by using other organisms as predators. The predators that are used are insects, mites, weeds etc. The natural enemy of insect pests is called predators, pathogens, competitors etc.
- Genetic engineering: It is the technique that can alter the chemistry of genetic materials like DNA in most cases and RNA in case of viruses to introduce these into host organisms and then change the phenotype of the host organisms. It also includes the repair of genetic materials to alter the phenotype which is suitable for human needs.
- Artificial control: In some buildings, the pest is controlled by attracting them with ultraviolet lights or with the usage of synthetic chemicals. Some are killed by electric currents while sometimes glue boards are used to catch cockroaches etc.
- Confusion technique: It is a technique to confuse the pest with the introduction of artificial stimuli that can confuse the individual and discontinue the mating cycle.
Hence, the correct option is A.

Note: Biological control is the most widely used process for pest control. It can be an important part of integrated pest management programs.
