Фенотипическая характеристика линий тутового шелкопряда Bombyx mori L. (Lepidoptera: Lymantriidae), отобранных по двигательному поведению гусениц

Abstract

A set of new criteria for industrial phenotype evaluation of Chinese silkworm lines have been established based on movement characteristics of the caterpillar. Lines CB-1071/1 и CB-1071/3, selected on these criteria, high biological parameters of the caterpillars and high technological properties of the cocoons and the silk thread (silkworm egg reanimation, 98.31–9.17 %; viability of caterpillars, 96.67 %; raw cocoon output per box, 41.320– 42.935 kg; raw cocoon weight, 2245–2309 mg; weight of silk membrane, 509.5–548.8 mg; silk ratio of raw cocoons, 22,17–24,75 %; length of silk thread, 1341–1408 m; thread fineness, 2.82–2.91 g/denier; reelability, 94.39–95.07 %, laboratory output of raw silk, 43.65–43.91 %. The new lines selected on these criteria will be proposed for testing and industrial use.
