Study of Rearing Performance of Six Eco Races of Samia ricini Donovan in Adverse Abiotic Conditions

The present research work was aimed to select an efficient strain of eri silkworm for low production costs of cocoons, adaptation to climatic factors of sub -tropical region like Bihar such as temperature and humidity leading to production of silk in high quantity and of superior quality. Better understanding to behavioural activities and performances of six strains of eri silkworm, Samia ricini D. such as GBP, GBS, GBZ, YP, YS and YZ during adverse abiotic conditions is a requisite in the larger interest of sericulture particularly eri culture development to a desired extent.
