description This research explores the potential of using common duckweed (<i>Spyrodela polyrhiza</i>) as a feeding substrate and supplement for yellow mealworm production. Duckweed is known for its high content of protein (20–35%) and essential amino acids. This study aims to assess the effect of the combination of semolina and duckweed as a feeding substrate for yellow mealworm larvae (<i>Tenebrio molitor)</i>. The experiment involved different combinations of semolina and duckweed in varying proportions. The treatments included 100% semolina (S), 75% semolina + 25% duckweed (S75D25), 50% semolina + 50% duckweed (S50D50), 25% semolina + 75% duckweed (S25D75), and 100% duckweed (D). Over a six-week period, the production parameters, nutrient composition, amino acid composition, and fatty acid composition of the yellow mealworms were measured and analyzed. The results demonstrate that S75D25 and S50D50 feed combinations were recommended due to their positive effects on production parameters and nutrient composition. Although the D substrate exhibited the highest crude protein content, yellow mealworm larvae did not grow on this substrate. The inclusion of duckweed in the feed had no significant effect on the fatty acid composition of the mealworms, while substrates S25D75 and D induced an improved amino acid composition. In conclusion, incorporating duckweed into the feeding substrate can enhance the production parameters and nutrient composition of yellow mealworms.
