Possibility of treating Varroa acariasis (Varroa jacobsoni oud) with natural substances

Abstract

Bee acariasis, caused by the mite Varroa jacobsoni Oudemans [26], represents a serious problem for apiculture. It is caused primarily due to the application of synthetic chemical miticides, which under certain conditions may result in the parasitism of bees. They become vulnerable to chemical treatment, along with probable deterioration of the quality of honey produced. This assay examines the possibility of treating bee Varroasis with a mixture of thymol, menthol and ethereal oils of eucalyptus and citronella. This mixture, in different doses, was applied to experimental hives and to regular Langstroh hives by means of specially-prepared pieces of moss. The greatest efficacy (89.71-90.20%) was found in both hives when the mixture was used in a dosage of 15 grams of thymol to one gram of menthol, 3 ml eucalyptus oil and 1 ml citronella.
