Detailed explanation-1: -Chemical secreted by an animal which influence the behavior of others in the same species. Aggregation pheromones. Promote the cohesion of animals. Alarm pheromones. Warn animals of possible predators.

Detailed explanation-2: -Aggregation pheromones gather conspecifics near the pheromone source, either by attracting them from a distance (attractant activity) or inducing passing conspecifics to remain at the pheromone source (arrestant activity)3. These pheromones can comprise a sole compound or multiple compounds.

Detailed explanation-3: -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.

Detailed explanation-4: -Most sex pheromones are produced by the females; only a small percentage of sex attractants are produced by males. Aggregation pheromones have been found in members of the Coleoptera, Collembola, Diptera, Hemiptera, Dictyoptera, and Orthoptera.

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.
