Kovalenko-Ruday N. Dynamics of biological and economically valuable indicators of silkworm culture in the process of directional selection according to viability

The object of researches is Selection after viability in artificial populyatsiyah of mulberry silkworm. Purpose of researches - to define the dynamics of biological and economic-valuable indexes of culture of mulberry silkworm in the process of the directed selection after viability. Methods of researches - are experimental, statistical. Results of researches: 1. For a theory - First on the culture of mulberry silkworm influencing of selection of visoko- and nizkogiznesposobnogo biomateriala is trained, that was carried out by complex application of the most effective receptions on three stages of development of silkworm (larvae, pupas and imago) on the dynamics of biological and economic-valuable indexes of culture. 2. For practice - the As a result conducted researches it is set, that complex application of four receptions of selection (selection after intensity of hemotaksisu on a traditional forage irritant; the selection 75 % individuals, that first perelinyali with І on ІІ age; selection of cocoons of the first two times of curling; selection of descendants from the имаго-females of the first three times of mass to the flow) on three different stages of development of mulberry silkworm is instrumental in the rise of index of viability on 9,68 % (p<0,01) comparatively with initial populyatsiey, that considerably promotes efficiency of production. The set advantage of selection after intensity of hemotaksis on a traditional forage irritant comparatively with the selection of larvae, that first perelinyali with I and ІІ eyelids, and complex application of two noted methods. The experimentally tested effective method of getting a culture out of the stress-situation caused by reduction of fattening area in three times is offered, by the selection of larvae on intensity of hemotaksis on a traditional forage irritant. Sphere of the use - the specialized enterprises from growing of silkworm.
