Honey bees at a hive entrance: one is about to land and another is fanning. Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees.

Stonebrood (aspergillosis larvae apium) is a fungal disease caused by Aspergillus fumigatus, A. flavus, and A. niger. It causes mummification of the brood of a honey bee colony. The fungi are common soil inhabitants and are also pathogenic to other insects, birds, and mammals. The disease is difficult to identify in the early stages of infection.
A less radical method of containing the spread of disease is burning only the frames and comb and thoroughly flame scorching the interior of the hive body, bottom board and covers. Dipping the hive parts in hot paraffin wax or a 3% sodium hypochlorite solution (bleach) also renders the AFB spores innocuous. [ 16 ]
The problem will progress up the plants until they’re virtually bare. General-purpose garden fungicides will control this late-spring disease that is made worse by water on leaves. Spider mites.
Deformed wing virus (DWV) is a positive-strand [1] RNA virus, one of 22 known viruses affecting honey bees.While most commonly infecting the honey bee, Apis mellifera, it has also been documented in other bee species, like Bombus terrestris, [2] thus, indicating it may have a wider host specificity than previously anticipated.
Valve springs that do not resonate are progressive, wound with varying pitch or varying diameter called beehive springs [15] from their shape. The number of active coils in these springs varies during the stroke, the more closely wound coils being on the static end, becoming inactive as the spring compresses or as in the beehive spring, where ...
A Horizontal top-bar hive is a single-story, frameless beehive in which the comb hangs from removable bars that form a continuous roof over the comb, whereas the frames in most current hives allow space for bees to move between boxes. Hives that have frames or that use honey chambers in summer and use management principles similar to those of ...
The small hive beetle primarily lives within the beehive and they are fed on pollen, honey and dead bees. The colonization can cause severe damage to honeycomb, stored honey, and pollen. [2] Beetle larvae may tunnel through combs of honey, feeding and defecating, causing discoloration and fermentation of the honey. If a beetle infestation is ...
