Even after these contacts virus-infected females made many frequent contacts with males and continued to call; they were found to produce five to seven times more pheromone and attracted twice as many males as did control females in flight tunnel experiments. [32] Pheromones are also utilized by bee and wasp species.
Sex pheromones are a special type of olfactory signal, produced to attract the opposite sex, to encourage mating or to perform some other function closely related to sexual reproduction. While humans are highly dependent upon visual cues, smells can also play a role in sociosexual behaviors .
Pheromones are chemical messengers produced and emitted by the body that contribute significantly to interpersonal attraction. [8] The two types of pheromones include signal and primer, each playing a distinct role in human behavior. Signal pheromones act as attractants and repellents; they are classified short-term behavioral pheromones.
Production of allomones is a common form of defense, such as by plant species against insect herbivores or prey species against predators. Sometimes species produce the sex pheromones of the organisms they exploit as prey or pollinators (such as bolas spiders [12] and some orchids [13]). Male sex pheromone of Dacini fruit flies, besides acting ...
Sex pheromones are pheromones released by an organism to attract an individual of the same species, encourage them to mate with them, or perform some other function closely related with sexual reproduction. Sex pheromones specifically focus on indicating females for breeding, attracting the opposite sex, and conveying information on species ...
Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species.

The amygdala (in olfaction) processes pheromone, allomone, and kairomone (same-species, cross-species, and cross-species where the emitter is harmed and the sensor is benefited, respectively) signals. Due to cerebrum evolution this processing is secondary and therefore is largely unnoticed in human interactions. [15]
