Abstract : Maximum incidence of Varrosis on adults of Apis mellifera L. (8%) was recorded in second fortnight of May 2008 corresponds to the peak in V. destructor population. Percent deformity was calculated by observing 100 adult bees. Deformity in adult bees was low which ranged between 0.0 to 3.0 per cent with an average of 0.52 per cent. Significant positive correlation (r = 0.77) was calculated between per cent mite infestation and per cent bee deformity which revealed that with increase in mite infestation, there was a corresponding increase in deformity of bees.
Keywords : Adult bees, Apis mellifera, Deformity, Varroa destructor.
