Answer 1

The correct option is B

Pheromones can lure insects into insect traps.

There are many ways by which pests can be controlled naturally. A pheromone trap is a type of insect trap that uses pheromones to lure insects. Pheromones of certain pest insect species, such as the Japanese beetle, acrobat ant, and the gypsy moth, can be used to trap the respective insect for monitoring purposes, to control the population by creating confusion, to disrupt mating, and to prevent further egg laying.

Pests can also be destroyed using ultrasonic sound waves or radiations. Another important way to control a pest is to introduce their natural predators. These eco-friendly methods reduce pollution in nature due to chemical pesticides.
