The varroacidal action of propolis: a laboratory assay

Abstract
– The action of propolis (bee glue) against the ectoparasitic mite
Varroa destructor
Ander-
sonandTruemanhasbeeninvestigatedandshowednarcoticandlethaleffects.Lengthofnarcosisand
rate of mortality depended on the extraction procedure, concentration of propolis and contact time.
Propolis extracted with 70% ethanol was found to be highly toxic, a 10% (w/v) propolis resulting in
100%mortalitywithabriefcontacttimeof5s.Inaddition,theeffectofpropolisonthemetabolicrate
of the mites has been investigated calorimetrically. Even sublethal propolis concentrations without
varroacidal effects and of only short lasting narcotic effects resulted in a significant reduction in the
heat production rate, indicating weakening of the mites.
