FEEDING PREFERENCE OF SILKWORM LARVAE DEPENDING ON BIOCHEMICAL ATTRIBUTES RELATED TO MULBERRY GENOTYPES
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2016, Vol 8, Issue 4
Abstract
Objective: The silkworm rearing was influenced by different mulberry cultivars according to the biochemical properties of leaves. In this present study, a comparative analysis was made to investigate feeding preference of silkworm larvae depending on biochemical attributes of mulberry genotypes.Methods: For this purpose, seven different mulberry cultivars and one germ plasm namely Dudhiya was selected. F1 hybrid (Nistari × bivoltine) of silkworm larvae was reared under selected cultivars of mulberry leaves at different seasons. Biochemical assessment of all leaves was also done.Results: Among these, S1, V1 and S1635 mulberry cultivars showed higher amount of total protein, total sugar and chlorophyll, also exhibited better feeding response on economic attributes of silkworm. Maximum accumulation of ascorbic acid and glutathione was recorded during winter in Dudhiya leaves. The accumulation of H2O2, superoxide and lipid peroxidation was comparatively higher than other cultivars during stress period in Dudhiya. Statistical analysis revealed that larval growth and economical parameters depend on biochemical properties of leaves and inversely associated with excessive production of Reactive oxygen species (ROS).Conclusion: The scavenger and ROS ratio was properly maintained in S1, V1 and S1635 leaves which might help leaf metabolic homeostasis. Proper metabolic activities of leaves possibly will produce higher proteins and carbohydrates which were required for larval growth and silk production as established from the PCA plot analysis. Therefore S1, V1 and S1635 might be recommended for silkworm rearing or commercial cultivation purpose throughout all season.Keywords: Silkworm, Mulberry cultivars, Proline, Reactive Oxygen Species (ROS), MDA, Single cocoon weight.Â
