Question

Biological control component is central to advanced agricultural production. Which of the following is used as a third-generation pesticide?

• A. Pathogens
• B. Pheromones
• C. Insect repellents
• D. Insect hormone analogues

Answer 1

The correct option is B Pheromones

Insect hormones, i.e., pheromones, are third-generation pesticides. Pheromones are chemical substances which when released into an animal's surroundings, influence the behaviour or development of other individuals of the same species.

A pathogen is a biological agent which disrupts the normal physiology of a multicellular animal or plant.

Insect repellents and hormone analogues are synthetic chemicals. Insect repellents are used to repel mosquitoes, ticks, flies, and other biting insects. Synthetic analogues of the insect hormones are used as an insecticide.
