MelanosisGroup of ovarian diseases, often changes color from yellow white to black. Causes sterility.
-Black eggs: Black grain like matter in ovary tubes. Caused by low temperatures - dysfunction of the metabolism of melanine reserves -Melanosis H: Nodular black lesions in ovary, vagina, rectum and poison gland. Caused by fungus 'Melanosella mors apis'. Infection peroraly by pollen. -Melanosis B: Ovaries become black (no nodules), disease takes time to completely manifest. Mostly in young queen bees. Caused by 'Aerobacterium cloacae jordani'. |

Obstruction of oviduct with semen cells
Rear of the abdomen is swollen, healthy fertilized queen bee does not lay eggs.
No eggs
In this disorder the queen bee actually lays eggs, but they are undeveloped - embryo is dead. Mostly manifests in young queen bees. Eggs themselves are deformed - flat. Caused by a genetic disorder.
|
Unfertilised eggs
Queen bee lays unfertilized eggs. Happens when the queen herself is unfertilized; when numbers of spermatosoids inside her depletes; disorder of spermatheca. This disorder is not treated, the old queen bee is replaced with a new one.

Kathalepsy (dizziness, paralysis)
The queen bee becomes phlegmatic and immovable for a short time period (few minutes - an hour (in rare cases even dies)). Caused by stress (handling with the queen bee, other outside factors). Queen bee needs to be left to rest for a while, usually does not have long term consequences.
|
Obstruction of oviduct with excrements (feces)Rear of the abdomen is widely opened with white or dark "plug" sticking out, healthy fertilized queen bee does not lay eggs (vagina is pressed by the feces). This condition can be treated - plug can be removed with some thin tweezers (pincette).

Anomalies in development of queen bee
Deformed queen bee: caused by lack of pollen and nectarines during larva period. Extremely small, does not lay eggs (sterile).
Deformed wings: At spring when the temperature suddenly drops. They can't take off, can be fertilized only artificially. Caused by genes.
Hypoplasy of ovary: causes sterility
Undeveloped oviducts: queen bee is sterile (both oviducts undeveloped) or lays less eggs (1 oviduct undeveloped). This means that there is no connection between the vagina and ovary. Queen bees can be artificially inseminated.
Changes due to aging: poison gland becomes black, synthesis of poison stops, malpighi vessels become yellow, there are more drone broods, they lay less eggs. If the beekeeper doesn't replace the queen bee - bees will.
