What is the primary method of communication among subterranean termites?

Pheromones are chemical signals that are produced and released by subterranean termites to communicate with one another. These chemicals serve as a means of conveying various types of information such as alerts to danger, the presence of food sources, or even cues for mating. The use of pheromones is particularly effective for subterranean termites because they live in dark, moist environments where visibility is low and sound may not travel as effectively.

The communication through pheromones allows member of the colony to coordinate their activities and maintain social cohesion, critical for their survival and efficiency as a social colony. This chemical communication system is integral to their behavior and interactions, facilitating tasks such as foraging and nest maintenance.

Other communication methods, like sound, visual signals, or nesting behavior, play a lesser role in termite interactions. For instance, while termites may produce some sounds or engage in certain visual displays, these are not the primary or most effective means of communication within their subterranean ecosystem.
