Studies on impact of weather parameters on seasonal incidence of diseases and enemies in Apis cerana were conducted at A. cerana apiary maintained by Department of Entomology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan during April, 2016 to March, 2017. European foulbrood disease incidence was statistically maximum (23.00%) in the month of July, 2016 when temperature, relative humidity and rainfall were high. Maximum incidence of Thai sacbrood disease was recorded during the month of May, 2016 (2.33%) when humidity was low (46.00%). No incidence of Nosema was observed during the study period. Thus the external weather parameters also influenced the disease incidence in the hive of A. cerana. The incidence of ectoparasitic mite (Tropilaelaps clareae) was maximum in the month of September, 2016 (10.00%), whereas, no incidence of Varroa destructor was observed. No incidence of wasps was recorded on A. cerana apiary, whereas wasps were found visiting A. mellifera apiary and maximum incidence (12.54±0.88) was recorded during the month of June, 2016.T. clareae incidence was positively correlated with temperature and relative humidity and negatively correlated with rainfall, whereas, wasp incidence was positively correlated with all the weather parameters.
