Pheromone
* Many pheromones act as male attractants.
* Most pheromone acts as sexual stimulants
  - attracts bees
* Most pheromone has functions
  - specific functions
* Most pheromone induces behaviour
  - courtship behaviour
  - is produced by glands
* Most pheromone is secreted by anal glands
* Some pheromone attracts adult beetles
  - butterflies
  - drones
  - insects
  - japanese beetles
  - mates
  - mice
  - silverfishs
  - termites
  - weevils
  - workers
  - has life
  - is expelled from glands
* Some pheromone is produced by anemones
  - queens
  - released by snakes
  - regulates reproduction
  - pheromones produce a very strong and immediate effects while others engender very little
* also deliver messages about a person's sexual state and general health
  - influence the human menstrual cycle
* are a chemical substance secreted by crabs and other creatures to attract each other
  - natural way of attracting women
  - naturally occurring chemical compound found in all insects, animals, and humans
  - sub-category of semiochemicals
  - airborne, odorless molecules that act as chemical signals
* are also common in vertebrates
  - important for communication
  - an important part of sexuality
  - behaviour modifiers
  - best when applied to collar and cuffs of wool or cotton fabrics
  - bile compounds found in the gall bladders of lamprey larvae
* are chemical scents playing a crucial role in human sexuality
  - sex attractants often used to confuse mating behavior of insects
  - substances, produced by insects, that influence their behavior
* are chemicals employed in intraspecies communication
  - given off by the female to attract males in order to mate
  - naturally produced by all humans
* are chemicals produced by animals allowing individuals of a species to communicate
  - insects to communicate
  - secreted by insects, and among other things they attract males to females
* are chemicals that carry messages that produce behavioral responses in other fish
  - communicate information among individuals of the same species
  - insects use to attract one another
  - the body produces to attract the opposite sex
  - used for communication in animals, including humans
  - which some species produce to attract mates
  - compounds emitted by insects to communicate with members of their species
  - considered a type of hormone
  - effective at very low concentrations
  - generally for communication, to let males know the female is ready to mate
* are hormones released by the body that play a large part in human attraction
  - that are thought to stimulate, through smell, sexual reactions in animals
  - important in sexual attraction
  - insect hormones
  - key chemical indicators in reproduction
  - natural aphrodisiacs
* are natural chemical scents the body produces in order to attract others
  - produces to the opposite sex
  - chemicals produced by wasps which attract other wasps
  - compounds that are created in the body of an insect
  - excretions to which the opposite sex responds
  - scents that influence insect behavior
  - naturally-occurring chemicals that insects use to find mates
  - natures way of attracting the female sex
  - now a popular subject for research
* are odorless chemical substances secreted by animals into their surrounding
  - chemicals secreted from the body that affect sexual behavior
  - hormonal secretions that stimulate the subconscious part of the brain
  - odorous substances secreted by various insects and animals
  - odors that are deliberately used for communication
  - powerful and can be detected for miles
  - released that attracts members of the same species
  - small, volatile, or water-soluble molecules that disperse into the environment
  - stinky chemicals excreted from glands throughout the ants body
  - substances that insects use to communicate and seek out one another for mating
  - subtle scents emitted by animals in mating season
* are the best-known form of communication in ants
  - chemical attractants produced by female moths to draw in males
  - chemicals insects use to find each other
  - natural scents insects use to communicate with each other
  - unreliable in the mid and late season for indicating whether sprays are needed
  - usually effective in tiny amounts
* are, to say the least, very effective stimuli.
* attract only males, whereas both sexes are captured in traps with a blacklight.
* attracts attention
  - mosquitoes
* can act at very small concentrations, below what the sense of smell can detect
  - also function in nonreproductive behavior
  - be very potent and have a very powerful influence on animal behavior
  - improve one's sex life
  - indicate whether a female is sexually ready to reproduce
  - persuade a person to act in a certain way without being aware of the reasons why
* communicate sexual attraction by the perspiration glands.
* create an aphrodisiac effect in women.
* creates strong attraction between the two sexes among animals, and also in humans.
* differ from sight or sound signals in a number of ways.
* have amazing potential
  - major influences
  - to be applied to the skin in order to mix and fuse with the human pH balance
* initiate reproductive development in new winged females, called female sexuals.
* maintain the cohesiveness and organization of the complex ant communities.
* make the job easier.
* only attract members of the same species.
* play a very important part in the sexual behaviour of many animals
  - an important part in reproduction and other social behavior
* play an important role in animals
  - the sexual isolation of insect species
* produced by the opposite sex, affect our reproductive cycles
  - in the tail and anal sacs provide sexual information for mating
* released by past ladybugs are detected by future generations.
* seem to affect people s general impressions and assessments
  - play an important role in mammalian social and sexual behavior
* sexually stimulates the opposite sex subconsciously.
* tell animals what they are supposed to do, such as run, fight or have sex.
* triggers reaction.
* work very differently from other insecticides.
+ Odor, Pheromones: Chemistry
  * Pheromones are odors that are deliberately used for communication. A female moth may release a pheromone that can entice a male moth that is several kilometers away. Honeybee queens constantly release pheromones that regulate the activity of the hive.
