The Physiology Of The Honey Bees

The physiology of the honey bees Sense of vibration and hearing

The fact that the bees can notice finest oscillations of the document, vibrations is not amazing with their predominantly dark bienenstock bound lives. One can demonstrate the sensitivity of their vibration perception easily, if one paints with damp finger over the window of a case. Then immediately all bees remain to be stood for a few instants as angewurzelt. Bees notice tones as vibration attractions over the underground, over their claw members and a sensory organ in the rail of their legs, which are called Subgenualorgan. It is by fine analysis of the bee dances was found out that bees " hear" an airborne sound to be able, even if only on shortest distance of few millimeters and frequencies from 100 to 800 cycles per second. Not the sound pressure, like with humans, is noticed but the speed of sound, the oscillation of air particles, which are sent in certain direction by the dancer over their wings. For the sound perception sensory hairs on the antennas seem to play a role and are probably also the Johnston organ in the turning member of the feelers in it involved.

Butterfly Hearing Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations. Butterflies may possess senses we don't even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses.

WASP The honey bee Johnston's organ consists of about 300-320 scolopidia connected with about 48 cuticular "knobs" around the circumference of the pedicel. Each scolopidium contains bipolar sensory neurons with both type I and II cilia. The mechanical sensitivities to sound waves of the antennal flagellum are specifically high in response to low but not high intensity stimuli of 265-350 Hz frequencies.

Mosquitoes mate on the wing. However, until the males reach maturity, that is to say during the first 24 hours of their short lives, they are not able to mate, for at this stage their antennae have not yet dried out. The deaf males cannot hear the sound of the females' wings, that is to say the mating call. Hearing is very advanced in mosquitoes. On the pair of small, hair-covered antennae on a male's head, there is an organ composed of numerous sensory cells. This system, which is known as the "Johnston's organ," receives the vibrations of sound waves and differentiates between them. These hairy feelers can only perceive sound waves when they are in an upright position. The sound produced by the wings of the female is the most important factor influencing the males. The wing sounds of the females cause the receptor cells on the male antennae to vibrate and send electrical signals to his brain. The wing-beat of the females is faster than that of the males, and the vibrations produced by the females' wings incite the males to mate. Let's think about the sounds we can hear on a summer day when there are plenty of mosquitoes around... traffic noise, people talking, animal sounds, in short a multitude of sounds, some of which are audible and some of which are inaudible to the human ear, depending upon their Antennae of the male mosquito. These feelers give the male an frequencies. It should be quite difficult for the extraordinary ability to pick out the sound of the female’s wing male to pick out the sound of the female beating beat from a thousand other sounds. her wings in the midst of this tumult of sounds. However, the sensitive "ears" of the male are able to distinguish the sound of the female out of all these sounds and he flies straight to the female to mate. When a female flies into a crowd of mosquitoes and is noticed by one of the males, she is held by special pincers located near the male sexual organ and mating usually takes place in the air, but sometimes on the ground. After mating, the male returns to the flock and after a time he dies. At this point the subject should be examined in more detail. There is a very interesting system at work. The mosquito
