Sentences with phrase «female sex pheromones»

According to lead author of the study, Dr Marinus De Jager of Stellenbosch University: «Since the discovery that the floral scent of these remarkable orchids mimics female sex pheromones, many of these compounds have been made in the laboratory.

Yet the female sex pheromone?

After conducting a range of different experiments, the researchers discovered that some of the chemicals left behind by the females, called sex pheromones, were largely responsible for keeping the males awake.

With its odor - sensitive antennae, the moth senses a target smell — in this case, female silkworm sex pheromones — and walks toward it along the trackball, driving the robotic car.

In the lab, and in field experiments, female brown rats readily enter trap boxes baited with the male brown rat's sex pheromone.

Using microelectrodes, the researchers recorded the electrical activity of pheromone - sensitive interneurons in male American cockroaches that relay signals of female - producing sex pheromones in the antennal lobe (functional homolog to the mammalian olfactory bulb) to higher - order centers.

A similar discovery in fruit flies, reported in an earlier independent study, which shows that a particular sex pheromone enhances female sexual behaviors and male aggression via separate neural circuits between the sexes, suggests that a sexually distinct circuit may be a universal strategy for converting male pheromone information into appropriate behavioral output.

Ever since a pheromone secreted by a female moth that attracts the opposite sex was identified in 1959, scientists have pinned down numerous chemicals that affect behavior in a wide variety of animal species, from insects to mammals to humans.

To find out whether sex hormones affect the number of neurons devoted to detecting female pheromones, the researchers removed the testes from male mice and the ovaries from females.

In moths, females emit a species - specific sex pheromone, consisting of a blend of biochemically related components, to which males are attracted.

In contrast, the Drosophila sex pheromone cVA is detected by both sexes and elicits dimorphic behavior by routing the signal via different third order neuronal circuits deep in the brains of males and females [19].

In silk moths, this is achieved by only males expressing the receptor BmOR - 1 in their antenna, which detects the female - specific sex pheromone bombykol [18].

Thus diversity in receptor expression can explain differences in odor sensitivity, but does not appear to dictate whether sex pheromones are differentially detected by males or females.

Before then, they assumed that B. germanica didn't need a volatile sex pheromone because the cockroaches live in close quarters where males could easily find females, Schal says.

However the contraceptive pill tampers with this cycle, so your smell receptors aren't as responsive to the male (or female) pheromone, and may reduce your interest in sex.
