none The experiment on parasitisation of wax moths by Apanteles galleriae Wilk. at the Himachal Pradesh Krishi Vishvavidyalaya, Palampur revealed that the population of Galleria mellonella L. (50 larvae/3 colonies) and Achroia grisella F. (250 larvae/3 colonies) was maximum during the first fortnight of August and second fortnight of July during 1993 and 1994 respectively. The parasitisation by A galleriae varied from 9.09 to 46.84, 11.11 to 47.14 per cent in case of G. mellonella and A. grisella respectively during 1993, whereas the respective values for 1994 were 14.29 - 44.0 and 8.33 - 46.34 per cent.
