29 Shoot rearing system Two feeds per day in shoot rearing system is recommended for bivoltine seed crop. 30 Leaf fortification Leaf fortification with Phosphorus, Zinc and Cholesterol has improved the rearing as well as grainage parameters. 31 32 33 34 35 Package for micronutrient management Egg recovery technology Botanical for improving silk content Centrifugal method for Moth examination Moth Preservation techniques 36 Preservation techniques for cross breeds 37 Incubation techniques 38 Technique for control of Stem Borer Zeuzera indica, a pest of muga host plants, Som and Soalu. Developed an integrated package of micronutrients for seed crop mulberry cultivation and young and late age silkworm seed crop rearing. The package helps to enrich the soil which is deficient in Boron, Zinc and Copper which helps in increase in quality leaf yield of 10 – 20%. Ethanol extract of botanicals Withania somnifera at 5%, or extract of Parthenium hysterophorus (5%) can be used for improving pupation rate and egg recovery of the silkworm without affecting the rearing parameters. Ethanol extract of Cassia tora (5%) is identified for improving the silk content of silkworm without affecting the grainage parameters. Standardized the centrifugal method of Mother Moth examination at low infection level during microscopic examination. During male moth preservation high humidity maintenance (80 – 85%) maintain the male potency upto 3 rd pairing resulting in high fecundity, less unfertilized eggs in CSR2 and CSR4 breeds. The long term preservation technique developed for cross breed eggs of Nistari(Nistari x NB4D2 and Nistari x CSR2) and multivoltines Nistari hybrids (Nistari x M12W and M12W x Nistari) can be preserved up to 70 and 50 days, respectively under double step preservation without effecting hatching and crop yield. Incubation techniques based on the effective accumulated temperature points (EATP) for the prediction of exact day of hatching were standardised for popular bivoltine silkworm breeds and their hybrids. Demonstrated in farmer’s fields, DOS farms and MSSO units. The technique is in practice. Integrated method by applying plant extract, chemical the pest can be controlled to the tune of 95% 28

Increase in yarn realization & production of finer count to get higher productivity & return Demonstrated in farmers fields. It is in practice at certain private farmers’ level. Introduced Ginger, Turmeric and Colocasia as intercrops in Som and Kesseru plantation for enhancing farm income. Two productive castor genotypes have been identified and introduced in the farmers field to get higher leaf yield. The protocol enables raising of plantlets from stem cuttings with a success rate of about 80%. The system facilitates propagation of desired genotypes, which hitherto were propagated through seeds. This reduces the gall infestation and facilitates availability of quality leaf for silkworm rearing. Indoor rearing of the chawki worms (up to 2 nd moult) ensures development of healthy worms with higher survival The combination SM5 increased the quality leaf yield by 27.45% in T. arjuna and 26.55% in T. tomentosa over control with significant improvement in cocoon characters The improved line of the Andhra local ecorace developed through hybridization with Daba shows higher fecundity (230), cocoon yield (26 cocoons/dfl) and filament length (802 m) over the Andhra local ecorace (fecundity: 190, Cocoon yield: 6 cocoons/dfl, filament length : 662 m) 29
