Sex pheromone production in European corn borer races explored -- tracking the origin of new species The coming of summer brings promise for humans and insects alike. The farmer planted maize for a bountiful harvest, but the European Corn Borer (ECB) is looking for a good meal right away. The caterpillars of this pest bore deep into the maize stems, where they eat the inner pith causing the weakened stalks to fall over before the ears can ripen. As if one pest were not bad enough, there are...

The researchers have named the pheromone 'darcin', after Jane Austen's hero in Pride and Prejudice, Mr Darcy. Darcin stimulates females to 'learn' an individual male's scent, reinforcing their memory of sexual attraction to that same male. Previous studies have shown that many mammals, from mice to elephants, use urine to communicate sexual attractiveness. In mice, females learn attraction to a male's scent through contact with urine and recall their attraction when the scent is detected at a...

The findings provide clues to how our brains work Scientists from The Scripps Research Institute have found a specific chemical compound secreted by many predators that makes mice behave fearfully. The research helps scientists better understand animal behavior, and may eventually lead to new insights into how sensory information is processed in human brains. The research was published in the prestigious journal Cell on May 14, 2010. "We're interested in how the brain can be hardwired to...

Researchers in the Department of Entomology,  University of California, Davis, have discovered that the fruit fly has a native odorant receptor that detects the silkworm moth's sex pheromone, and that it's "amazingly more sensitive" than the moth's odorant receptor. Their work could open research doors for insect-inspired biosensors. The odor detector or OR is a means of chemical communication that helps insects find mates.  The olfactory link between silkworm moths (Bombyx mori)...

To look at the tobacco budworm moth and its close cousin, you wouldn't be able to tell the fuzzy-looking, fingertip-size moths apart. But put males of each species as far as six car-lengths away from females,  and even in the darkness of midnight they easily find their way to mates from their own species while ignoring females from the other species. Today, the genes that keep the species sexually isolated are no longer a mystery, thanks to research from North Carolina State University...

The vomeronasal organ (VNO) is an odor detection system that mediates many pheromone-sensitive behaviors. Vomeronasal sensory neurons (VSNs), located in the VNO, are the initial site of interaction with odors and pheromones. How an individual VSN transduces chemical signals into electrical signals, however, has been a mystery. In the January 2010 issue of the Journal of General Physiology (www.jgp.org), researchers from the University of Vermont show that a Ca 2+ -activated chloride current...

Humans have the same receptors for detecting odors related to sex as do other apes and primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to Duke University researchers. Varying sensitivity to these sex-steroid odors may play a role in mate selection -- and perhaps prevent cross-species couplings, the researchers speculate. The researchers analyzed the sequences and functions of the gene for the odorant...

Study, published in Nature, also identifies pheromone-detecting neurons in the fly's antenna Have you ever found yourself struggling to get your order taken at a crowded bar or lunch counter, only to walk away in disgust as more aggressive customers elbow their way to the front? It turns out that flies do much the same thing, according to biologists from the California Institute of Technology (Caltech). Reporting in the advance online edition of the journal Nature, the scientists say they...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...
