Title : Seasonal incidence of greater wax moth (Galleria mellonella L.) in Apis cerana colonies in relation to ecological conditions

Abstract :

The greater wax moth Galleria mellonella L. belonging to order Lepidoptera and family Pyralidae, is an economically important and most devastating pest of honey bees. It attacks all the species of Apis and cause a great economic loss to the beekeeping industry all over the world. Seasonal incidence of greater wax moth (Galleria mellonella) in Apis cerana in relation to weather parameters were conducted at A. cerana apiary maintained by Department of Entomology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan during January 2019 to December 2020. Pooled data on greater wax moth incidence showed that the mean population of the greater wax moth arrayed from 0.83 to 8.97. Seasonal incidence of greater wax moth started in the month of February and the highest number of larvae, pupae and adults were recorded in the month of July (13.10, 9.10 and 4.70, respectively) when the temperature relative humidity and rainfall were high and after that population declined till November. Minimum incidence of wax moth population was observed in the month of February (1.20, 1.30, 0.00) and no incidence were found in the month of December and January when the temperature and rainfall were low. It was observed that weather conditions during summer and rainy period (May to September) were more favorable for greater wax moth development in A. cerana colonies. Wax moth population has a highly significant positive correlation with temperature. While the colony strength, brood area, relative humidity and rainfall has a positive non-significant correlation with wax moth incidence. Wax moth adults showed positive significant correlation with rainfall.
