Efficiency assessment of modified defined chemical compounds for controlling varroa mite, Varroa destructor (Parasitiformes : Varroidae)‎ in Egyptian apiaries

Abstract EN

Varroa mites, Varroa destructor Anderson and True man (Parasitiformes : Varroidae) are external parasites that attack both honey bees and brood.

They suck the blood from both the adults and developing brood, especially drone brood.

This weakens and shortens the bee’s life.

Emerging brood may be deformed with missing legs or wings.

Untreated infestations of varroa mites will increase and may kill colonies.

If the colonies are not examined for mites, losses may be mistaken for winter mortality or queenlessness.

The present work is to study, the efficacy of the two chemical compounds, Bayvarol and VarroKiller acaricides were tested separately against the varroa mite, within the honey bee colonies located in the stations of the Beekeeping Research Department in four Egyptian Governorates as a reevaluation of them after their development by the companies producing them.

Both compounds showed their qualitative superiority in the treatment of the colonies under study and reduce the infection of parasite on the adult bees below the minimum levels compared with the untreated colonies, and Bayvarol was a more superior than VarroKiller compound.
