Detailed explanation-1: -Pheromones are chemicals produced by one species that affects the physiology or behavior of animals of the same species. Pheromones assist in reproduction, feeding, social interactions and maternal-neonatal bonding in mammals. By definition and according to evolutionary theory, pheromones work within a species.

Detailed explanation-2: -Pheromones are typically secreted by specialized glands or tissues. For example, female moths have a pheromone gland at the end of their abdomen. Rodents have a wide variety of skin glands as well as large and small pheromone molecules delivered in their urine.

Detailed explanation-3: -Bees, wasps, ants, moths and other insects rely largely upon pheromones as a means of communication. Pheromones are chemical substances which may be secreted in urine, dung or produced by special glands. They are usually given off by the female of the species to attract males.

Detailed explanation-4: -Pheromones. Pheromones are chemical substances that are created and emitted by organisms as odorants-often as oils or sweat-into the environment that may influence the behavior or physiology of other members of their species. This is particularly the case for mammals or insects.

Detailed explanation-5: -A pheromone is a species-specific chemical signal that incites a response in another organism. Pheromones are involved in a wide variety of behaviors, including mate selection, food acquisition, alarm responses, territory marking, predation defenses, and other social behaviors indicating social status.
