Economical modification has been reported in the popular artificial diet of the most commonly used fictitious host waxmoth, Galleria mellonella for mass-multiplication of entomopathogenic nematodes. The suitability of the modified artificial diet composition on the biological parameters like larval weight, duration, pupal weight, duration, fertility and overall survival and developmental period for five generations were also assessed. The investigation on detailed biology, carried out during the present study indicated that replacing the honey with the honey waste has no significant negative effects on the larval period, larval weight, survival of the larvae, duration of pupal stage, total developmental period, pupal period and adult emergence, i.e., pupal mortality. Thus, the composition-II with modified proportions of the constituents and containing honey waste proved economical, suitable and best artificial diet for G. mellonella. Further, rearing was continued for five more generations on the Composition-II with calculation of the economics in INR, which further proves that the composition-II can be successfully used even for commercial mass-multiplication of the galleria waxmoth larvae.
