Originated in ancient times, mulberry silkworm farming is a cost-effective sub-sector of agriculture. The strong dependence on food needs and especially the seasonality and distribution area of mulberries are limiting factors in the rearing of larvae.In our country Morus alba grows well and gives high yields of foliage in certain seasons of the year due to its characteristics. The resulting leaf mass has a high nutritional value. An alternative to nutrition is artificial food. It allows for growing in any season of the year, regardless of external climatic conditions. Some plant extracts are food stimulants and improve food intake, growth and even disease resistance. The aim of the present study was to test a hybrid I1xVB1xH2xHB2 created in Scientific Center on Sericulture, Vratsa, Bulgaria, for susceptibility to artificial food with added extract of Origanum vulgare L. as a growth stimulant. Tracking the most important biological, reproductive and technological features of silk larvae and butterflies; Artificial food was readily accepted by Bombyx mori L. Higher values were observed in the experimental groups fed with artificial food and added extract, we observed the growth intensity of the larvae and their viability.
