How do ants communicate with each other?

Introduction

Ants are highly social insects that rely on complex communication systems to coordinate their activities and maintain their colonies. Understanding how ants communicate with each other is crucial for comprehending their social structure and behavior.

Key Insights

Chemical Communication:
- Ants primarily use chemical signals, such as pheromones, for various forms of communication including alarm signaling, recruitment, and territorial marking .
Acoustic Communication:
- Ants also use acoustic signals, produced by stridulation (rubbing body parts together), to convey important information. These sounds are often used in combination with chemical signals to enhance communication .
- Acoustic signals can indicate social status within the colony, especially among pupae, which use these sounds to maintain their position in the social hierarchy.
Mechanical Communication:
- During cooperative tasks like transporting large objects, ants communicate through the forces they exert on the load, which helps them coordinate their movements.
Context-Dependent Communication:
- Ants modulate their stridulatory signals based on the behavioral context, such as foraging or interacting with different castes within the colony. This flexibility allows them to convey specific information relevant to the situation.
Intercolony Communication:
- Ants engage in ritualized combat and display behaviors to communicate with rival colonies, which helps them gauge the strength of their opponents without engaging in physical fights.
Development of Communication Skills:
- Young ants (callows) are more communicative and require interactions with adult ants to develop their communication skills. This suggests that experience plays a role in the maturation of their communication abilities.

Conclusion

Ants utilize a multifaceted communication system that includes chemical, acoustic, and mechanical signals. Chemical communication is the primary method, but acoustic signals play a significant role, especially in social hierarchy and context-specific interactions. Mechanical communication is crucial for cooperative tasks, and intercolony communication helps in conflict resolution. The development of communication skills in young ants highlights the importance of social interactions in their maturation. Together, these communication methods enable ants to maintain their complex social structures and efficiently coordinate their activities.

Analysis of acoustic communication by ants.

Ants communicate mainly through the air, with hairlike sensilla on the antennae responding to particle sound velocity, and can exclude extraneous sound and determine the direction and distance of a near-field source.

Acoustic communication within ant societies and its mimicry by mutualistic and socially parasitic myrmecophiles

Ants use acoustic communication to enhance social communication, and other invertebrates mimic these signals to coexist with ants or exploit their resources.

Ant Pupae Employ Acoustics to Communicate Social Status in Their Colony’s Hierarchy

Ant pupae use acoustic signals to communicate social status in their colony hierarchy, potentially replacing semiochemicals as a means of identification.

The physics of cooperative transport in groups of ants

Ants communicate mechanically to move objects, posing a transition between uncoordinated and coordinated motion, with leader ants acting as temporary informants.

Ants modulate stridulatory signals depending on the behavioural context

Ants use vibrational signaling as a flexible communication channel, varying signal patterns and parameters depending on the behavioral context and caste of the emitter.

Ritualized combat and intercolony communication in ants

Ant display tournaments in Myrmecocystus mimicus colonies serve as a mechanism for intercolony communication, allowing opposing colonies to gauge each other's strength and determine food gathering boundaries.

Myrmica rubra Ants Are More Communicative When Young: Do They Need Experience?

Young Myrmica rubra ants are more communicative than adults, suggesting they need prolonged contacts with adult nestmates to gain the experience of communication.

Acoustic communication by ants

Ants communicate using a combination of pheromones and sound, with stridulatory signals transmitted through the air due to the ant's size and the significant near field surrounding the ant.

Ethological Aspects of Chemical Communication in Ants

Ants use chemical communication to repel predators, recruit, and communicate with their guests, with motor displays and mechanical signals playing a significant role in these behaviors.

Communication in Ant–Plant Symbioses

Ant-plant communication primarily involves chemistry, with its importance in selecting seeds, detecting host plants, pruning exogenous vegetation, and providing plant protection.
