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)
'Hansel and Gretel' ants use geometry to find their way home
Scientists at the University of Sheffield have discovered that Pharaoh ants use angles to determine the direction of a trail, informing them whether they're travelling to or from the nest. The study, published in Nature on 16 December, explains how ants know which direction they are travelling in when following pheromone trails. view more (2004-12-15)
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)
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)
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)
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)
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)
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)
UC Davis research could lead to no scent, no sex for the Japanese beetle
If a male Japanese beetle is unable to detect the sex pheromone released by a female, he won't be able to locate her and reproduce. view more (2008-06-30)
Scientists discover how to send insects off the scent of crops
Biotechnology and Biological Sciences Research Council (BBSRC)-funded research, published this week in Chemical Communication, describes how scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food... view more... (2009-09-24)
Chemical come-on successfully lures love-sick lampreys to traps
A synthetic chemical version of what male sea lampreys use to attract spawning females can lure them into traps and foil the mating process of the destructive invasive species, according to Michigan State University scientists. view more (2009-01-22)
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 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)
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)
Pesky fruit flies learn from experienced females: Study
A common household nuisance, the fruit fly, is capable of intricate social learning much like that used by humans, according to new research from McMaster University. view more (2009-09-17)
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)
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)
How the 100th protein structure solved at Diamond impacts our understanding of how insects smell
New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture. view more (2009-09-30)
1 missing gene leads to fruitless mating rituals
Male fruit flies missing a gene for one particular odor receptor become clueless in matters of love, scientists at Duke University Medical Center have discovered. view more (2008-07-24)
