Abstract

Formic acid vapours have shown to be an acceptable alternative to Apistan (Fluvalinate) in the control of Varroa jacobsoni, a parasitic mite found on honey bees. However the open delivery systems currently used in the industry put the beekeeper at unnecessary risk from direct exposure and vapour inhalation of the acid. In this study, an alternative closed system for the delivery of formic acid vapours to beehives has been investigated. Formic acid as an aqueous solution (65%, v/v) is contained in a latex membrane through which the vapour diffuses. On reaching the outer surface it vaporizes into the hive. Estimates of the amount of formic acid vapour that can pass through these membranes indicate that it is possible to deliver 10 g of material to the beehive on a daily basis. This would be sufficient to control Varroa mite infestation. Furthermore the method of delivery is safe, effective, and inexpensive.
