Insect pheromones are chemical signals produced by insects to communicate with one another. These substances can convey various messages, such as attracting mates, marking territory, or alerting others to danger. Different species of insects use specific pheromones, which can be detected by their antennae, allowing them to respond appropriately to the signals. Pheromones play a crucial role in the social behavior of many insects, including ants, bees, and termites. For example, ants use trail pheromones to lead others to food sources, while bees release pheromones to signal alarm or attract mates. Understanding these chemical signals helps researchers study insect behavior and ecology.
