ABSTRACT

It is known that the cocoons of the average fraction (caliber and mass) in the breeding party are the most productive part of it. By the method of mathematical statistics, the regularities of division of the mixture of breeding cocoons by caliber and mass are determined. The normalized proportion of the average cocoon fraction of 58-70% and its range of caliber-2 mm determined and the possibility of maximum separation of defective components with small and large fractions from the batch in two stages, when sorting cocoons by caliber and mass was revealed. The article presents the technical characteristics of new devices developed on the basis of the revealed regularities and intended for sorting cocoons by caliber and dividing them by mass (sex) in the process of preparing hybrid silkworm eggs, which differ in increased accuracy of dividing cocoons by caliber and mass, as well as contributing to the replacement of manual labor and a sharp increase in productivity. The results of technological indicators of cocoons and raw silk obtained from them are presented.
