Question

The first sex attractant pheromone identified was that of
a) Cat
b) Dog
c) Gypsy moth
d) Human

Answer 1

Hint: A pheromone is a synthetic factor that is released and causes a social reaction in individuals of similar species. Pheromones are synthetics designed to act like chemicals outside the body of the emitting individual in order to influence the behaviour of those receiving them.

Complete answer:
A pheromone is a substance factor that is emitted or discharged and causes a social reaction in individuals of similar species. The Gypsy moth pheromone was the first to be identified as a sex attractant pheromone. Sex pheromones are pheromones released by a living being to attract a person of a similar species, entice them to mate with them, or perform some other function directly related to sexual pheromone.
Sex pheromones are designed to attract females for reproduction, repel the opposite gender, and transmit information about species, age, sex, and genotype. Non-volatile pheromones, also known as cuticular contact pheromones, are more strongly associated with social bugs because they are normally recognised by direct contact with chemoreceptors on the reception apparatuses or feet of bugs.

Hence, option C- Gypsy moth is the correct option.

Note:
Pheromones that induce a change in the beneficiary's actions are known as releaser pheromones. For example, some living beings use incredible attractant particles to attract mates from two miles or more away. This type of pheromone usually elicits a quick response, but it is quickly degraded. A groundwork pheromone, on the other hand, has a slower start and a longer length. Bunny (moms) release mammary pheromones, which encourage their children to nurse more often.
