Egyptian bee propolis for controlling some honeybee diseases in hives [electronic resource].

Includes references.

The current work was conducted in honeybee apiary located in Diarb Negm, Sharkia governorate during 2012-2013. Bee propolis (bee glue) was collected from honeybee colonies by using propolis traps. Ethanolic extract was used for this study to evaluate honeybee colony strength (brood area (cm² )), Varroa infestation level and chalkbrood infestation level. The obtained results summarized that Italian bees (Apis mellitera ligustica) significantly collected more propolis than Carniolan bees (Apis mellifera carnica). It also concluded that ethanolic propolis extract significantly decreased Varroa infestation level, meanwhile, it didn't effect neither brood area (cm²) nor chalkbrood infestation level. The data recommended that ethanolic propolis extract may be used for protecting honeybee colonies from Varroa infestation.
