The use of silk moth, as an object of biological research, raises the need to create alternative sources of cheap food. The objective of this study was to determine the susceptibility of species Bombyx mori L. to artificial diets with reduced content of dried mulberry leaf. The study has been carried out at the educational and experimental facility of the Silkworm breeding section of the Faculty of Agriculture at Trakia University. The studied 45 breeds from the genetic bank of SAES - Vratsa were reared with artificial diet with 15% content of mulberry leaf powder, provided by SAES - Vratsa and prepared by methodology recommended by the manufacturer. The receptivity of specimens from the analyzed breeds was determined based on the survival rate of larvae in the Ist, IInd and IIIrd instar of the caterpillar stage. The results obtained showed that the vitality of the breeds included in this study varies widely: 53.76 - 100%; 26.49 - 98.75% and 0 - 95.67%, respectively for the first, second and third instar. Lower limit of survival in rearing with artificial food is over 70% vitality. In all three instars of the larval development, with over 70% vitality, and therefore high degree of receptivity to the artificial diet with low mulberry powder content was shown by the breeds "Almeria esp 1" (100.00% → 95.67%), "Nig 2" (97.94% → 80.05 %), "Vratsa 2003" (96.72% → 85.88%) and "Veslets 1" (95.91% → 72.99%). The high percentage of survival rate established in the majority (82.22%) of the analyzed 45 breeds during in the first instar and therefore, with high affinity to artificially prepared food low in dried mulberry leaf, is indicative of the biological potential of rearing them with artificial diet with low content mulberry powder (15%).
