[Economic effect of using a comprehensive program for the control of Varroa infestation]

The control of Varroa infestation in honeybees embraces a system of veterinary measures requiring an overall economic evaluation as a prerequisite for the wide use of a special programme. A comparative economic analysis of the dynamics of the process is made for two periods: a basic one, when no programmed control measures have been taken, and a planned one, when the programme has been put into practice and the results thereof by the end of the time are compared with those of the basic period. Employed has been the method of the index factorial analysis taking into consideration the complex and individual effects of definite factors, contributing to such effects. The increased absolute volume of material expenditures (chiefly therapeutic agents) is reflected in the absolute and the relative growth in the end-product economic results obtained with the two apiaries studied.
