Ascosphaera apis (Onygenales; Ascosphaeraceae) is known to be a heterothallic fungi and the causative agent of the chalkbrood disease. Germinated spores in the intestinal tract of the brood lead to a mummification of the host. If untreated, the pathogen causes death of infected brood due to enzymatic toxicological and mechanical damage. [1] [2]
Ethiopia: A. apis is present and its geographical distribution and infestation rate is unequal within Ethiopia. Desalegn (2006) surveyed apiaries around Holeta and found that chalkbrood occurred in 17.4% of inspected honey bee colonies. [3] Unfortunately, only cryptic information is available on chalkbrood disease in Ethiopia (e.g. treatment options, distribution pattern, severity, ...). [4] [5] According to a local scientist, chalkbrood is nowadays common in Ethiopian honey bee colonies, but the disease seems to have minor effects on the colonies, and therefore no treatment is applied (pers. communication with the Holeta Bee Research Center).
