Eight different diets were compared for maximum production of entomopathogenic nematode infected Galleria cadavers with cheaper/ low cost in the laboratory. Among eight artificial diet composition tried, low grade milk powder 100 g, low grade glycerin 100 ml, honey 100 ml, corn flour 200 g, wheat bran 100 g, wheat flour 100 g and yeast 50 g produced almost maximum Galleria larvae with EPN infected cadavers and EPN infective juveniles (IJs) with cheaper cost while, the diet containing, ragi powder 100 g instead of milk powder, honey 100 ml, high grade glycerin 100 ml, corn flour 200 g, wheat bran 100 g, wheat flour 100 g and yeast 50 g produced least number of EPN infected Galleria cadavers and EPN IJs. Among the diet compositions, sugar solution 100 ml instead of honey along with other ingredients used, did not emerge or produce larvae from the Galleria eggs.
