Orphan date January 2011 The Pheromone Biosynthesis Activation Neuropeptide PBAN is a neurohormone member of the PBAN Pyrokinin neuropeptide family that activates the biosynthesis of pheromone s in moths. Moth females release PBAN into their hemolymph during the wikt scotophase scotophase to stimulate the biosynthesis of the unique pheromone that will attract the conspecific males. PBAN release is drastically reduced after mating, contributing to the loss in female receptivity. ref cite journal last1 Rafaeli first1 Ada title Pheromone biosynthesis activating neuropeptide PBAN Regulatory role and mode of action journal General and Comparative Endocrinology volume 162 issue 1 pages 69 78 year 2009 pmid 18495120 doi 10.1016 j.ygcen.2008.04.004 ref Molecular mechanism of action The precise regulatory mechanisms exerted by PBAN on the different steps of pheromone biosynthesis remain to be determined.

pp semi small yes Image Nasinov 9024.JPG right thumb Fanning honeybee exposes Nasonov gland white at tip of abdomen releasing pheromone to entice swarm into an empty hive A pheromone from Greek language Greek phero to bear hormone from Greek impetus is a secreted or excreted chemical factor that triggers a social response in members of the same species . Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. ref http www.medterms.com script main art.asp?articlekey 12896 ref There are alarm signal alarm pheromones , food trail pheromones , sex pheromones , and many others that affect behavior or physiology. Their use among insect s has been particularly well documented. In addition, some vertebrate s and plant s communicate by using pheromones. Background The term pheromone was introduced by Peter Karlson and Martin L scher in 1959, based on the Greek word pherein to transport and hormone to stimulate . They are also sometimes classified as ecto hormones. They were researched earlier by various scientists, including Jean Henri Fabre, Joseph A. Lintner, Adolph Butenandt, and the prominent ethologist Karl von Frisch who called them various names like alarm substances. These chemical messengers are transported outside of the body and result in a direct developmental effect on hormone levels or behavioral change. ref Kohl, J., Atzmueller, M., Fink, B. & Grammar, K. Human Pheromones Integrative Neuroendocrinology & Ethology. NEL 22, 309 321. 2001 ref They proposed the term to describe chemical signals from conspecific s that elicit innate behaviors soon after the German Biochemist Adolf Butenandt characterized the first such chemical, bombykol a chemically well characterized pheromone released by the female silkworm to attract mates . ref cite journal doi 10.1038 183055a0 author Karlson P., L scher M. year 1959 title Pheromones a new term for a class of biologically active subst ... more details
