The application of a naturally occurring pheromone to honey bee test colonies increases colony growth resulting in stronger hives overall, according to a new study conducted by scientists at Oregon State University and Texas A&M University. The study, which appeared this week in the journal, PLoS ONE, comes amid national concern over the existence of honey bee Colony Collapse Disorder (CCD) "“ a combination of events that result in the death of a bee colony. The causes behind CCD...

Researchers believe the findings represent the first detailed evidence of an aggression-inducing contact pheromone in any aquatic animal When male squid come into contact with a chemical found on the outside of eggs laid by females, they instantly go from swimming along calmly and minding their own business to a state of extreme aggression, according to a new report published online on February 10 in Current Biology, a Cell Press publication. After just a touch of an egg, males will often...

Male bedbugs are known to be very unfussy when it comes to mating, mounting any well-fed bug they can see - regardless of age or gender. Researchers writing in the open access journal BMC Biology have discovered how immature bedbug nymphs, who would be harmed by the traumatic insemination technique practiced by the males, release alarm pheromones to deter this unwanted attention. Vincent Harraca, from Lund University, Sweden, worked with a team of researchers to stage encounters between males...

In the battle between insect predators and their prey, chemical signals called kairomones serve as an early-warning system. Pervasively emitted by the predators, the compounds are detected by their prey, and can even trigger adaptations, such a change in body size or armor, that help protect the prey. But as widespread as kairomones are in the insect world, their chemical identity has remained largely unknown. New research by Rockefeller University's Joel E. Cohen and colleagues at the...

The defining feature of social insects is that societies contain queens, which specialise in laying eggs, as well as workers, which are mostly infertile but take care of the offspring and the nest. However, when the queen dies or is re-moved, workers begin laying eggs of their own. Previous observations have suggested that queens possess a specific pheromone which keeps the workers infer-tile, but the pheromone has never been identified except in the well-studied honeybee. Queen pheromones...

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...

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)...

The capybara (also capibara) (Hydrochoerus hydrochaeris) is a semi-aquatic herbivorous animal, the largest of living rodents. It is endemic to most of the tropical and temperate parts of South America east of the Andes. It has been introduced to north-central Florida and possibly other subtropical regions in the United States. It is the only living member of the family Hydrochoeridae. Description and habits Full-grown capybaras reach between 40 to 55 inches (105 and 135 cm) long, and...
