Abstract

The ecto-parasitic mite Varroa destructor is a serious world-wide pest of the honey bee Apis mellifera and has being linked with the death of millions of colonies, though its role is not completely destroyer of the colony. The aim of this study was to determine the seasonal infestation of bee colonies in Fars province to the Varroa mite is devastating the honey bee. Samples of adult bees and pupae were collected from 120 apiaries in the spring, summer, autumn and winter during 2012-2013. Samples were taken from 30 apiaries in each season. For determining of infestation of adult bees, infected samples put inside the glass containing 70% ethanol. For determining of infestation of larval stages and pupae, in appropriate time from the side of the hive frame, a piece with dimensions of 5 × 5cm apart and with the ice was transported to the laboratory. Lowest rate of varroasis spread was in spring (30%) and it increases in the following seasons respectively and the highest rate was occurred in winter (50%). During the year infestation was found 39.2% of the apiaries. No significant difference was observed between the infection rate in different seasons (P>0.05).
