Detailed explanation-1: -Trail pheromones, as the name implies, are used by social insects to lay down an odour trail which other members of the species can follow to guide them from the nest to a food source and back again.

Detailed explanation-2: -Trail pheromones are used for recruitment, for marking pathways to resources, and for indicating resource richness. Often released with alarm pheromones, trail pheromones enable guards to aggregate around a nest invader. Furthermore, short-lived and persistent trail pheromones are known.

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: -Trail Pheromone: Certain ants, as they return to the nest with food, lay down a trail pheromone. This trail attracts and guides other ants to the food. It is continually renewed as long as the food holds out. When the supply begins to dwindle, trailmaking ceases.

Detailed explanation-5: -Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology.
