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.
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]
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 ...
Pharaoh ants (Monomorium pharaonis) mark trails that no longer lead to food with a repellent pheromone, which causes avoidance behaviour in ants. [22] Repellent trail markers may help ants to undertake more efficient collective exploration. [23] The army ant Eciton burchellii provides an example of using pheromones to mark and maintain foraging ...
Ant paths built from pheromone traces Stigmergy ( / ˈ s t ɪ ɡ m ər dʒ i / STIG-mər-jee ) is a mechanism of indirect coordination , through the environment, between agents or actions. [ 1 ] The principle is that the trace left in the environment by an individual action stimulates the performance of a succeeding action by the same or ...
Trophallaxis in carpenter ants Camponotus sp.. Trophallaxis is a form of social feeding in many insects that contributes to the formation of social bonds. [5] Trophallaxis serves as a means of communication, at least in bees, like M. genalis, [16] and ants. [17]
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 ...
Unlike ants, bees also use "dance language". This very complex behaviour allows foraging bees to communicate to their sisters the location of resources and dangers in the foraging space all through dancing movements. [7] However, inside the dark chambers of the nest itself, complex pheromone systems are used to communicate and organize the ...
