Biological criteria for accepting of bee bread as a mite food by Tyrolichus casei Oudemans (Acarina: Acaridae)

Journal of Apicultural Science. Volume 47, Issue 1, Pages 21-25, ISSN (Print) 1643-4439
The object of the study was to confirm the possibility of the development of Tyrolichus casei Oudemans on bee bread and the acceptance of this product by mites as evidence that these pests might threaten the provisions of honeybees.
Monocultures of the species were set up from specimens collected from hive debris and were kept in the laboratory at temperature ca. +20°C, RH - about 85%; bee bread was used as mite food. Biological experiments were conducted under the same conditions.
Some live parameters (average) of T. casei were as follows: embryonic development - 3.4 days, complete life history - 14.5 days, mortality of juvenile instars - 10.0%, frequency of females - 52.2%, longevity of adults - 101.8 days, oviposition period - 34.3 days, fecundity of females per lifespan - 426.3 eggs.
These results show a comparatively high biological potential for raising T. casei on bee bread and confirm a working hypothesis as concern the attractiveness and effectiveness of this kind of medium in rearing acarid mites. Evidence is presented that cheese mites are potential pests of stored hive products.
