Semiochemicals

Semiochemicals are natural chemicals emitted by plants, animals, or microorganisms that influence the behavior or physiology of other organisms. They serve as communication signals, helping organisms find mates, warn of danger, mark territory, or coordinate social activities. Examples include pheromones used by insects to attract partners or alarm substances released to alert others of a threat. These chemicals are important in ecosystems for maintaining interactions among species and can also be harnessed in agriculture for pest control or pollination management.
