Experimental investigations were carried out under controlled laboratory conditions with the aim of elucidating the particularities of the ontogenetic development cycle of the species Plodia interpunctella (Hübner), an important economic pest at a global level. The experiments aimed to estimate the influence of three distinct types of nutrient substrates, both in macerated and non-macerated form, on the biological parameters of this species, including the duration of larval stages development, survival rate and reproductive efficiency. These investigations were designed to highlight the impact of nutrient media compositions on the eco-physiological performance of individuals, thus contributing to a better understanding of the trophic adaptation mechanisms of this phytophage under laboratory conditions with the perspective of including it in the technological process as a host for the multiplication of the entomophage Bracon hebetor.
