Honey bee chemoreceptors found for smell and taste
Honey bees have a much better sense of smell than fruit flies or mosquitoes, but a much worse sense of taste, according to researchers at the University of Illinois at Urbana-Champaign. view more (2006-10-26)
New study examines how sense of smell affects mating and aggression in mice
New research by scientists at UCSF sheds light on how the odor detecting system in mice sends signals that affect their social behavior. view more (2005-12-22)
Researchers discover key gene involved in bark beetle pheromone production
University of Nevada, Reno scientists have ended a decade-long controversy over the process by which bark beetles make pheromones: they manufacture their own monoterpenes - the fragrant substances plants produce and which are often used in perfumes. view more (2005-06-28)
Past experience of pheromones induces dominant courtship behavior in fruit flies
By investigating the interplay between pheromone signaling and behavior in fruit flies, researchers have begun to understand how an adult fly's earlier experience as a young individual can influence its behavior towards other flies as an adult. view more (2005-10-11)
Edge density key to controlling gypsy moth spread
Controlling population peaks on the edges of the gypsy moth range may help to slow their invasion into virgin territory, according to a team of researchers. view more (2006-11-16)
Pheromone from mother's milk may rapidly promote learning in newborn mammals
By studying the ability of newborn rabbit pups to learn the significance of new odors, researchers have found that a mammary pheromone secreted in mother's milk may act as a chemical booster that facilitates the ability of pups to quickly associate environmental odors with the opportunity to nurse. view more (2006-10-10)
For honey bee queens, multiple mating makes a difference
The success of the "reign" of a honey bee queen appears to be determined to a large degree by the number of times she mates with drone bees. view more (2007-10-09)
Mate or hibernate? That's the question worm pheromones answer
If worms could talk, they might tell potential suitors, "I like the way you wriggle," complete with that telltale come slither look. view more (2008-07-25)
Scientists uncover how hormones achieve their effects
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory [EMBL]. view more (2007-10-23)
Love bites
Biology PhD student Gill Horne and her supervisor, mosquito expert Dr Angela Priestman, have been studying the mating behaviour of mosquitoes in special hotrooms at the University's School of Sciences. view more (2000-01-18)
Pheromones - an evolutionary trick?
Female pheromones - airborne chemical messengers - may have evolved to trick men's thought processes: they can block men's ability to judge women's attractiveness. view more (1998-12-03)
Lacewing species new to Britain unexpectedly detected in field trials of aphid sex pheromone
Scientists from IACR-Rothamsted1 and Imperial College were surprised to find large numbers of green lacewings in traps baited with a plant-derived compound aimed at improving natural biocontrol of aphid pests2. Close inspection by Stephen Brooks at the Natural History Museum identified these lacewings as Peyerimhoffina gracilis, a species new to... view more... (2001-12-17)
Entomologists play matchmakers for cerambycid beetles
Cerambycid beetles, also known as long-horned beetles, can cause severe damage to standing trees, logs and lumber. How then might they be promptly detected and their numbers swiftly controlled? view more (2008-08-06)
Love calls from the bottom
Some men send flowers, others send chocolates. But one species of fish has a rather unusual method of seducing the opposite sex. Researchers at the Centre of Marine Science, University of Algarve, Portugal, have been studying how the peacock blenny fish secretes pheromones – chemical ‘love’ signals – from an anal gland. view more (2002-04-04)
Scripps research scientists discover chemical triggers for aggression in mice
The work, reported in an advance, online issue of the journal Nature on December 6, 2007, furthers the broad and important goal of elucidating how the neurological system can detect and respond to specific cues in of a sea of potential triggers. view more (2007-12-07)
Pheromones Identified that Trigger Aggression between Male Mice
A family of proteins commonly found in mouse urine is able to trigger fighting between male mice, a study in the Dec. 6, 2007, issue of Nature has found. view more (2007-12-06)
Alarm pheromone causes aphids to sprout wings
Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-ß-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. view more (2005-05-18)
Accessory protein determines whether pheromones are detected
Pheromones are like the molecules you taste as you chomp on a greasy french fry: big and fatty. view more (2007-10-18)
Sex and lifespan linked in worms: a family of sugar-like molecules controls both
A group of scientists who set out to study sex pheromones in a tiny worm found that the same family of pheromones also controls a stage in the worms' life cycle, the long-lived dauer larva. view more (2008-07-24)
University invention enlisted in battle against the brown-tailed moth
An environmentally friendly insect trap devised by researchers at the University of Southampton is the latest weapon in Portsmouth City Council's long-running battle to control infestations of the caterpillars of the brown-tailed moth. view more (1998-09-04)
