Pheromone-based communication is one of the most effective ways of communication which is widely observed in nature. Pheromone is used by social insects such as bees, ants and termites; both for inter-agent and agent-swarm communications. Due to its feasibility, artificial pheromones have been adopted in multi-robot and swarm robotic systems.
Ant communication in most species involves pheromones, which is a method using chemical trails for other ants or insects to find and follow. [ 1 ] However, ants of some species can communicate without using pheromones or chemical trails in general.
Structural formula of bombycol, the first clearly chemically identified insect pheromone. Insect pheromones are neurotransmitters that serve the chemical communication between individuals of an insect species. They thus differ from kairomones, in other words, neurotransmitters that transmit information to non-species organisms.
Chemical communication within a species can be usurped by other species in chemical mimicry. The mimic produces allomones or pheromones to influence the behaviour of another insect, the dupe, to the mimic's advantage. The process is important in ant mimicry where species that do not look like ants are accepted into the ant colony.
In some countries the weaver ant is a highly prized delicacy harvested in vast amounts and in this way contribute to local socio-economics. [36] In Northeastern Thailand the price of weaver ant larvae is twice the price of good-quality beef and in a single Thai province ant larvae worth US$620,000 are harvested every year.
In regards to foraging, an ant can communicate the quality of a food source to its colony; the more rewarding a food source is, the higher the concentration of the trail produced. [8] Additionally, some species, like Lasius niger ants, can "eavesdrop" on the trails produced by another species in order to procure food.
Pharaoh ant workers have a non-functional stinger used to generate pheromones. [5] The petiole (narrow waist between the thorax and abdomen) has two nodes and the thorax has no spines. Pharaoh ant eyesight is poor and they possess on average 32 ommatidia. [6] The antennal segments end in a distinct club with three progressively longer segments.
When an ant is killed, it releases a pheromone that alerts others of potential danger. Pheromones also help ants distinguish family members from strangers. The queen ant has special pheromones which she uses to signal her status, orchestrate work, and let the colony know when they need to raise princesses or drones. [4]
