Detailed explanation-1: -Pheromones are used as communication cues between individuals of the same species. Ants use trail pheromones to help other members of the colony get from their nest to a food source and return to the nest again in an efficient manner.

Detailed explanation-2: -Trail pheromones are produced primarily by social insects that forage on the ground, such as termites and ants, although a few nonsocial insects also use them. Termites, for example, continually produce trail pheromone from abdominal glands and deposit a drop each time the abdomen touches the substrate.

Detailed explanation-3: -What are examples of pheromones? An example of pheromones is Bombykol, which is used by Wild Silk Moths from the species Bombyx mandarina. Female moths secrete bombykol to trigger sexual responses in male moths.

Detailed explanation-4: -Pheromones are chemical signals that have evolved for communication between members of the same species. A pheromone signal elicits a specific reaction in the receiver, for example, a stereotyped behavior (releaser effect) or a developmental process (primer effect). Some pheromones can have both effects.

Detailed explanation-5: -For example, when a rabbit leaves a scent to convey a message to another rabbit, the scent is a pheromone. However, the coyote that follows the same rabbit’s scent cannot read the chemical message. To the coyote, the scent is an odor, not a pheromone.
