Pheromones are natural chemical scents the body produces in order to attract others. They are well documented in the animal kingdom as the force that controls all social behavior, including mating. Scientists are now finding that human behavior is also heavily influenced by these invisible social magnets.
A mystery chemical isolated from the sweat of young women seems to act as a romance booster for their older counterparts. When the researchers added the compound, Pheromone 10:13, to a perfume and gave it to older women, it made their partners more affectionate.
“In diaries kept by the women for 6 weeks, 41 percent of pheromone users reported more petting, kissing and affection with partners,” New Scientist magazine said on Wednesday.
Joan Friebely of Harvard University and Susan Rako, a doctor from Newton, Massachusetts, studied the behavior of 44 post-menopausal women. Half were given a perfume with the compound while the remainder used a fragrance with a placebo or dummy chemical.
Only 14 percent of women using the perfume with the placebo reported an increase in affection from their partners.
The study, also published in the Journal of Sex Behaviour, said 41% of pheromone users reported more kissing and affection from their partners, compared with 14% who […]

Pheromones are chemicals emitted by living organisms to send messages to individuals of the same species. The idea that chemical communication takes place between individuals of the same species was advanced as early as the late 17th century the first evidence in support of this was obtained in the 19th century by the French priest Henri Fabre, whose hobby was raising butterflies. Fabre demonstrated that antennae are the butterfly’s organ of smell and that males are attracted to females for reproduction during their flight season. In the 1930s in Czechoslovakia, females of deciduous fruit pests were used as bait to trap males in an attempt to monitor the presence of the pest in the orchard and subsequently devise an appropriate pest control treatment.
The sex pheromones were first isolated and identified by German scientists in the year 1959 in silk moth. Although the presence of these pheromones were identified early 1959 only, it had not come to the lime light until early 1980’s when the media started poking its nose in the matter.
Technical progress in handling minute quantities of chemicals, coupled with the development of sophisticated electronics and computerization, led to rapid progress that enabled the isolation and characterization of three […]

The exquisite specificity of insects chemical language is not surprising, considering that it is often the only means insects have for finding each other. Researchers have now broken the code for the pheromone communication of more than 1,600 insects. In so doing they have found that pheromones serve many more purposes than simply attracting mates.
As already discussed, Pheromones are powerful sex attractants. Till now hundreds of pheromones are known with which one sex (usually the female) of an insect species attracts its mates. Many of these sex attractants (Pheromones) - or their close chemical relatives - are available commercially and these are proved very effective as Pesticides against many pests in two ways:
1) Male Confusion
Distributing a pheromone throughout an area masks the insect’s own sex attractant and thus may prevent the sexes getting together. The male cannot find the respective female for more than hundred days and hence the offspring rate reduces extensively. This “communication disruption” has been used successfully against a wide variety of important pests. For example, the sex attractant of the cotton boll weevil has reduced the need for conventional chemical insecticides by more than half in some cotton-growing areas.
2)Insect Monitoring
Insect Pheromones are also valuable […]
