list of diseases of the honey bee









































diseases of the honey bee or abnormal hive conditions include:









































section::::pests and parasites.









































section::::pests and parasites.:"varroa" mites.









































"varroa destructor" and "varroa jacobsoni" are parasitic mites that feed on the bodily fluids of adult, pupal and larval bees.









































"varroa" mites can be seen with the naked eye as a small red or brown spot on the bee's thorax. "varroa" mites are carriers for many viruses that are damaging to bees. for example, bees infected during their development will often have visibly deformed wings.

presently the "varroa destructor" mite is the single greatest threat to bee colonies in ireland. if left untreated colonies will die within three to four years, although typically after the initial infestation there can be a rapid increase in the mite population which would lead to colony collapse. varroa mites arrived in ireland in 1998 and in several years had spread throughout most of the island. the mortality rate for over-wintered colonies during 2015/16 in the republic of ireland was 29.5% and for northern ireland was 28.2%; for comparison wales was 22.4% and scotland was 18%, the european average was 12%. as a result of varroa there are now no wild colonies surviving, feral colonies, swarms that have escaped from apiaries, will die within a short time, however their hives can be re-occupied afterwards by new swarms for the cycle to repeat; these feral colonies can become a source of large varroa populations, this and the fact that varroa has shown resistance to previously effective treatments can result in regional loses as high as 40-60%. on the occasions where feral colonies appear to be able to survive with varroa on a long term basis, closer study has discovered that the local strain of varroa have become non-lethal as opposed to the bees becoming resistant or in which the varroa acts as a host to a non-lethal deformed wing virus (dwv), both of which are exceptionally rare and non-reproducible, therefore a parasite management system must be maintained to continually manage the varroa mite. as an alternative to treatment against the varroa mite and in the hope to re-establish a wild population, in 2013 a varroa tolerance breeding program was set up by nihbs, focusing solely on the "a. m. mellifera", in conjunction with several breeding groups throughout ireland, including the galtee bee breeding group (gbbg) whose apiary manager, micheál mac giolla coda (a former president of bibba, fibka and founding member of nihbs), in 2012 stated that "the plan is to harness the bee’s natural defences against the mite" by improving the bees "grooming and hygiene habits" through selective breeding "by observing the number of damaged mites" without dna analysis nor the use of instrumental insemination; in 2009 research was published that showed that marks on mite's exoskeletons, previously attributed as damage caused by grooming was more likely to be mere "regular dorsal dimples (indentations)"; in 2018 it was announced that varroa resistant "buckfast" bees would be made available for sale in 2019, modern methods of breeding, such as instrumental insemination, had been used to impart this genetic trait into the wider "buckfast" population. to date there has been no progress of such breeding projects towards imparting varroa resistance into the "a. m. mellifera" population in ireland. research was conducted in 2017 to determine if the "a. m. mellifera" in ireland possessed varroa resistant characteristics, which had been observed in other "a. mellifera" such as the "buckfast bee", the conclusion was that it possessed no such resistance against the varroa mite.
