The present study was designed to investigate the efficacy of nutrient media on the development and mortality of the life stages of the phytophagous Gallerria mellonella. Thus, in order to study the con-ditions and factors affecting the cultivation of Galleria mellonella in laboratory conditions and the biolog-ical efficiency of its rational use, it was necessary to investigate the effect of nutrient media on the mor-phophysiological parameters of G. mellonella; a physic-chemical analysis of the ingredients of the nutri-ent media under study, etc. Thus, some authors recommend for reproduction in laboratory conditions a complex composition of media, including containing vitamins, protein, various sources of fat, carbohy-drates; but also to be, at low cost.
