Abstract:
Commercial beekeeping is highly threatened by a number of biotic stresses that included different mite pests. An experiment was conducted in the Apiary unit of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal, India during 2018-19 and 2019-20 season to assess the seasonal incidence of different parasitic mites on the European honey bee, Apis mellifera Linn. colonies in the terai agro-ecological region of West Bengal. Ten number of strong A. mellifera colonies were used for the study. Incidence of both varroa mite, Varroa destructor Anderson and Trueman and tracheal mite, Acarapis woodi (Rennie) was found maximum during summer months, whereas during the winter months incidence of A. woodi was significantly lower and incidence of V. destructor tended to zero. Incidence of V. destructor was recorded maximum in month of June during both 2018-19 (14.40±2.70 mites/100 bees or 6.125±1.13 mites/100 brood cells) and 2019-20 (15.05±2.69 mites/100 bees or 6.350±1.19 mites/100 brood cells) seasons. Incidence of A. woodi was recorded maximum in May-June month, i.e. 34.50% bees infested in June month during 2018-19 and 28.00% bees infested in May month during 2019-20.
