People have long been "tamed" the bees before the former wild, and now successfully use them for honey, basically.As a by-product - propolis, pollen, beeswax, bee venom.And use these hardworking insects for pollination of many plants can not be overestimated!On apiaries and cottages often seen unpretentious hives inhabited by bees, carefully bringing people to the products of their vital functions.Today we will talk about the structure of these insects, their senses.How do they see and how much the eyes of bees, learn from our article.
Senses
Bees are guided in the outside world through the senses.These include: vision, hearing, smell, taste, and others.
smell and touch.They help to maintain the spatial orientation of a bee in a dark nest or hive.Olfactory organs are located on the antennae of an insect.Some hairs covering the body of the bee, are the organs of touch and connected with the nervous system.Interestingly, drones then responsible for the sense of smell, is several times larger than conventional bees.
organs of taste and located in the throat bee and her proboscis, on the legs and antennae.
And hear the sounds of the insects with the help of which are on the legs and other parts of the body.
By the way, there are bees and other bodies responsible for a better perception of the world.They analyze the atmospheric humidity, the temperature difference, the amount of content of carbon dioxide in the air.These organs allow the bees to control climate for the optimal development of housing in the cells of larvae of insects.
How many eyes of the bees?
separate issue - the visual organs.If you look at from afar medonositsu, to the question: "How many eyes have bee?" You're likely to answer: "Two."And wrong.Because in fact, as many as five!With a visual sense knocked two large compound eyes, located on the sides of the head and having the form of two ovals.There are three simple eyes located on top of the head of an insect, but they are visible on closer inspection.Let us more detail on the question of how much the eyes of bees.
Simple
Three simple, located on the top of the head, provide photographic vision and resemble a camera.In them, as on a photographic plate, reproduced visible objects (affect branched end there).All three images in the eyes of ordinary bees add up to one thing by imposing.
Complex
How many eyes have bee?Photo rarely allows us to give the right answer to this question.Quite differently made compound eyes of an insect.If you look at the structure of the eye bees under a microscope, you can see the structure of the body.The entire surface - mesh.It is composed of thousands of facets (mikroploschadok in the form of a hexagon).The facets, by the way, its structure reminiscent of a honeycomb.From facets to the nerve endings are opaque tubes and into which a visual signal.Thus, the body of the insect is fused together in a large number of cells.At the working bees of up to five thousand, drone much more - up to eight.At the uterus - five thousand small holes in each compound eye.This type of vision is called the facet and is found in many insects (such as flies).
mechanism of
Each cell-facets responsible for only part of the image.Such parts of the visible object could be thousands, and they all add up in the brain of a bee into a whole.As a variant of this name - a mosaic.
If the complex organs of the picture consists of a plurality of images, the simple eyes of insects are looking at objects up close.Interestingly, with the exclusion of possible facet of bees behave like a blind or visually impaired, and can see things just flying up to them close enough.Complex as the eyes of a bee is able to survey the large spaces, which allows it to navigate during flights.
