  • chemical
  • Doty, however, argues that the chemical stimuli that mammals respond to are typically combinations of many compounds, that are sensed in complex social situations, and experience and learning are important for how mammals respond to chemical stimuli. (wikipedia.org)
  • moths
  • Here we show that Helicoverpa zea males exposed to an attractive pheromone blend (and in some instances to the primary pheromone component alone) started shivering earlier and took off at a lower thoracic temperature than moths subjected to other incomplete or unattractive blends. (biologists.org)
  • In noctuid moths, as in several other insects, female receptivity and sex pheromone production decrease subsequent to mating (e.g. (biologists.org)
  • In an experiment with heliothine moths, male hair-pencil compounds were extracted and tested against various male and female treatments. (wikipedia.org)
  • Heliothine moths use similar hair-pencil compounds in different ratios and this is enough for the female to differentiate conspecifics from other species. (wikipedia.org)
  • colognes
  • There are quiet a few companies that produce types of pheromones and colognes that have the particular how to seduce a girl: the trick behind hooking up with girls . (userboard.org)
  • Industries which produce pheromone colognes are rising in popularity nowadays since most savvy marketers recognize the good potential for making money from the public customers who are looking for better ways on how to nail the opposite sex. (mystopgap.com)
  • insects
  • The study of insect pheromones has recently attracted great attention because of their purely scientific interest and their favorable prospects for the control of pest insects. (lsu.edu)
  • While the pheromone concept applies reasonably well to insects , Doty argues that there are serious problems with its application to mammals. (wikipedia.org)
  • species-specific
  • Doty shows that the effect depends on experience, that multiple compounds found in male mouse urine are involved in the effect, and the effect is not species specific since urine from male rats will also cause puberty acceleration in young female mice. (wikipedia.org)
  • urine
  • For example, the Vandenbergh effect in mice occurs when puberty -accelerating pheromones are released in the urine of male mice. (wikipedia.org)
  • This compound does not originate in the tarsal gland itself, but rather it is extracted from the animal's urine by the tarsal hair tuft during the rub-urination process. (wikipedia.org)
  • In white-tailed deer, the presence and concentration of certain chemical compounds in the urine depend on the season, gender, reproductive status and social rank of the animals. (wikipedia.org)
  • blend
  • Second, males detecting the pheromone blend take off at lower thoracic temperatures than males exposed to other stimuli. (biologists.org)
  • If the female likes the male blend of pheromones, then she will extend her abdomen and copulation begins. (wikipedia.org)
  • produce
  • If you are feromonas for sale mate or a sexual spouse it is a good idea to consider using one of these if you think you do not produce enough of the a look at pheromones odorless cologne. (userboard.org)
  • The two host strains of S. frugiperda produce systematically differing female sex pheromone blends. (biomedcentral.com)
  • Men and women are attracted to the pheromones they produce and HLA is related to the perceptions of other peoples' odours. (wikipedia.org)
  • perception
  • The differential activation is likely to trigger different downstream circuitry and underlies the concentration-dependent pheromone perception. (pubmedcentralcanada.ca)
  • The study in this dissertation aims at the elucidation of some important aspects of the mechanism of perception of insect pheromones, which is based on the fact that the cyclic analogs of the natural pheromone have partially fixed conformations, whereas the straight-chain natural pheromone is more flexible and can adopt numerous conformations. (lsu.edu)
  • composition
  • Relative to intra-strain variation, the pheromone composition of the two strains differed significantly. (biomedcentral.com)
  • Different populations differing in location (specifically Southern Italy, the Balkans, and Centre-Eastern Europe) have experienced genetic differentiation in pheromone composition. (wikipedia.org)
  • genetic
  • Most other compounds showed an inheritance indicating genetic dominance of the corn strain. (biomedcentral.com)
  • Finding the genetic basis of the pheromone differences, as well as these other biological traits, will help to elucidate the role of premating isolation in the continuing differentiation of these two strains that may eventually lead to speciation. (biomedcentral.com)
  • specific
  • Six male-specific compounds were detected and were identified through the use of mass spectrometry, nuclear magnetic resonance (NMR) spectrometry, chiral and achiral gas chromatography, high-performance liquid chromatography, electrophysiology (gas chromatography-electroantennography, GC-EAD), and microchemical tests. (springer.com)
  • This collection of compounds is the least specific of all pheromones. (wikipedia.org)
  • isolation
  • The finding of pheromone differences reinforces the possibility of incipient reproductive isolation among these strains, previously shown to differ in the timing of nocturnal mating activity and host plant use. (biomedcentral.com)
  • important
  • During the past ten years a variety of methods involving mass spectrom- etry have been developed for the analysis of environmentally important compounds. (springer.com)
  • They are so important that stepping on a substance containing these compounds causes immediate proboscis extension in adults. (wikipedia.org)
  • significantly
  • With respect to the second area of focus, the discovery and patented protection of new mood-enhancing compounds, the Company filed a final U.S. Patent Application and a European filing for a compound that has shown significantly enhanced positive feelings and emotions in both men and women.

  • mammals
  • The Great Pheromone Myth is a book on pheromones and their application to chemosensation in mammals by Richard Doty , director of the University of Pennsylvania 's Smell and Taste Center in Philadelphia . (wikipedia.org)
  • According to Doty, those critical of the book range from people who refuse to read it to those who have semantic issues with the pheromone concept and its applicability to mammals. (wikipedia.org)
  • Attraction
  • During my initial research I discovered that Max Attraction Gold, is pretty much the flagship pheromone cologne produced by a company known as LuvEssentials. (mystopgap.com)
  • Being well aware in which many folks are still blindly stumbling round the internet in search of real information regarding attractant pheromones, after listening to the name Maximum Attraction for years, but finding no reliable information on this pheromone spray, I opted to give it a go!

  • SAN JOSE, Calif., March 27 /PRNewswire-FirstCall/ -- Human Pheromone Sciences, Inc. ("HPS" or "the Company") today announced results for the three months and the year ended December 31, 2008. (biospace.com)
  • Over the past couple of years, we developed a multi-faceted program to be less dependent on any one customer, seek additional licensees in the U.S. and abroad for our original pheromone technologies, complete scientific validation on our most promising mood-enhancing compound and present the results to consumer marketers.

  • For example, androstenedione is a steroid hormone that is found in human sweat and is the main ingredient in commercially sold human pheromone products, but scientific research provides little evidence that it functions as a pheromone. (wikipedia.org)
  • In particular, pyrrolizidine alkaloids have been found to play a role in male pheromones. (wikipedia.org)
