Studies were conducted on the number of wasps attacking honeybees (Apis mellifera) colonies in three different times of the day for six continuous minutes every day on ten honeybee colonies. The study period was divided into 35 Standard Meteorological Weeks (SMW) among which the wasp incidence varied significantly, as recorded and low in early spring with a gradual increase in the late summer and the highest peak was observed in the autumn. The results showed that the maximum weekly population of predatory wasps at morning, mid-day and evening was (8.667), (27.394) and (13.052) respectively, during 38th SMW. Weekly mean population of wasps exhibited positive correlation with the maximum temperature and negative correlation with the minimum relative humidity. Monitoring the seasonal activity and spatial population variations, along with weather parameters indicate the estimate of peak period of their activity by which sustainable management strategies/plans of these predatory wasps will be developed.
