Parthenogenesis in bees: Causes and Treatment. Uterus-trutivka.
There are several options reproduction of living organisms: sexual and asexual, ie without parental cells.
Bees line between sexual and asexual reproduction erased. The method of reproduction called parthenogenesis toilers bees.
parthenogenesis – a specific method of reproduction, in which the developing fertilized and unfertilized eggs.
As it happens? uterus – female bees, which has a well-developed ovaries and genitals, so it can mate with drone.
During mating the male gives his semen womb. In her stomach has a special receiver, and which stores sperm. After mating, the male dies, and the female laying eggs set to.
Two ways of laying eggs in the bees
The first method is used, When the egg is deposited in the center of drone (parthenogenesis).
Uterus hairs on the abdomen feels cell size, for the working bee is 5,5 mm, but for the drone 7 mm.
In accordance, in contact with drone Soto tummy uterus gives unfertilized egg, from which grow drone.
In working cells queen lays eggs the same, only seven opening”yapryemnyk and dripping cum on them.
From these eggs out worker bees or queen.
Why queen lays unfertilized eggs into working cells?
It happens so, that parthenogenesis occurs in the process of laying eggs in working cells, but then they hatch drones.
The causes of parthenogenesis in masonry in small cells:
- in the absence of sperm in the uterus receiver;
- Death of male cells in spermopryymachs because of poor living conditions of the uterus;
- cum over (passed 3-4 years after fertilization).
Parthenogenesis is not considered a disease in laying unfertilized drone cells in cell.

Drone grow only unfertilized cells. The problem arises, When the queen lays "empty" egg in working cells. Of these drones come in the future, is unacceptable.
Why not seed bag Queen sperm?
This may be because, during breeding season was non-flying or cold weather and no uterus zaplidnyv. In accordance, sperm in the bag initially was not.
Therefore, this will delay the uterus only empty cells.
Stock exhausted by sperm 3-4 years of life uterus, in accordance, then the queen will delay "empty" egg.
With insufficient feeding and improper temperature regime sperm inside the uterus abdomen becomes dead.
How to cure parthenogenesis in bees?
Treat the disease correctly, This form of reproduction intact without the use of male cells.
If everything is in order, uterus simply opens the seed channel and put in an empty cell hundredth trutnevuyu.
Working bees lay eggs
Ideally worker bee must collect nectar, her ovaries are underdeveloped and there are seven”yapriemnika, that it can not lay eggs with hard worker.
But it happens, what worker bee instead of collecting nectar delayed drone eggs, such insects called trutovkamy. They are not allowed in the new hive fertile females, killing them.
To return the bees to normal, to get rid of and stop trutovok parthenogenesis. You can shake the evening sun bees from the hive.
A little later, the worker bees return to the hive, and let there not trutovok. These bees die scatter Second hives or die.
