A comparative analysis of morphological anomalies in seasonal and regional samples of Varroa destructor Anderson and Trueman, 2000 was conducted. It was found, that the abnormality rate of most morphological characters increases from spring to summer and, conversely, decreases from autumn to winter.

The peculiarities of dynamics of a level of varroatosis in adult bees in the Zacarpatye, Poltava regions and in the Crimea in 1996???1997 years are specified in work. Is revealed, that the speed of development of varroatosis invasion during a season is higher in of bees family carpathian race, and also at intensive conducting beekeeping and the ...

Veterinary Parasitology: Regional Studies and Reports
The honeybee (Apis mellifera) ectoparasite, Varroa destructor, is one of the most important honeybee pests worldwide. Acaricides, including the pyrethroids (tau-fluvalinate, flumethrin), and organophosphate (coumaphos) have been applied to control this mite within apiaries, still the long-term, constant, and excessive use of these products has led to ...

The study of seasonal variability of mite V. destructor was carried out. The summer generation of mites appears to be characterized by the largest morphological variability whereas the winter one has stable characters. We failed to evolve the complex of morphological characters that would allow us to identify, with high level of reliability, certain ...

Ανάλυση της ανθεκτικότητας του βαρρόα, Varroa destructor(Acari: Varroidae)σε ακαρεοκτόνα
2016Μελετήθηκε η ανθεκτικότητα του Varroa destructor στα ακαρεοκτόνα coumaphos, τ-fluvalinate, amitraz. Αρχικά διερευνήθηκαν τα επίπεδα ανθεκτικότητας σε φυσικούς πληθυσμούς Varroa από την Άνδρο, τη Νάξο και την Αττική με κλασικές μεθόδους βιοδοκιμών και συγκρίθηκαν με τον ευαίσθητο πληθυσμό αναφοράς AUA.
