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.
Ants typically use trail pheromones to coordinate roles like nest defense and foraging. [6] Ants can produce a trail of defensive secretions that trigger an alarm response within their nestmates. [7] 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 ...
Depending on the function, there are different emission and reception scenarios. Ants, for example, emit alarm pheromones intermittently or continuously in the usually windless environment of the anthill. Trace pheromones are emitted by an ant as a moving source. Silkmoth sex pheromones are emitted in discrete scent threads in an air stream. [57]
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.
Along with nutrients, trophallaxis can involve the transfer of molecules such as pheromones, organisms such as symbionts, and information to serve as a form of communication. [1] Trophallaxis is used by some birds , gray wolves , vampire bats , and is most highly developed in eusocial insects such as ants , wasps , bees , and termites .
The returning worker ants have also been found to emit more pheromones than those leaving the nest, causing the difference in concentration of pheromone in the trails. [21] The pheromones will allow foraging to be much more efficient by allowing the army ants to avoid their own former paths and those of their conspecifics. [19]
Tandem running in termites involves communication via sex pheromones, and all mating pairs engage in this process. For these reasons, tandem running in termites is considered a form of sexual behavior. The following ant frequently touches the legs of the lead ant with its antennae to maintain contact in the tandem run.
Physiology of eusociality in fire ants: three queen pheromones help to create and maintain the eusocial state of the colony. Loss of a primer pheromone triggers the development of replacement queens (dashed lines). [83] [84] Among ants, the queen pheromone system of the fire ant Solenopsis invicta includes both releaser and primer pheromones. A ...
