Резюме: The aim of the study was to analyze main reproductive, biological and technological characters in the normal and double cocoons offspring. It was found that using double cocoon offspring do not result in any significant changes in the parameters like fecundity, average weight of one laying and one egg, number of eggs in one gram, hatchability, viability and larval duration. Double cocoon offspring possess higher values regarding in any of the parameters lice cocoon shell ratio, filament length, silk ratio and reelability. Considering results obtained from the present study it is possible to recommend utilization of the double cocoons in seed production.
