1. Most of these compounds are phenolic compounds, alkaloids, flavonoids, saponins, etc. Silkworm Seed (Egg- Polu koni) is the backbone of silk industry. • It can also be reared on host plants similar to that of tasar worms. ... Amazing Silk Processing form silkworm - Silk Farm Harvesting - Duration: 7:41. Growth and development of muga silkworm feed on different food plants. â¢ It can also be reared on host plants similar to that of tasar worms. In order to improve the productivity of this silkworm it is important to have a better knowledge of both its host plants and biology. The silkworm â¦ Geographical isolation of this silkworm is indicative of its special requirements for geo-climatic conditions that prevail in this region i.e. The primary food plant of eri silkworm is castor and 41 accessions are maintained. This species is variable, with at least 44 identified eco-races, populations adapted to varied ecological conditions and food plants. Highlighting some of the differences in varieties of Muga host plant. 11:19-21. kept the sericulture in India economically unattractive. Further, the, Sericulture is an industry that is characterized by a two-step process, the cultivation of mulberry trees and the rearing of silkworms on mulberry leaves to produce cocoons. The recent advances in Biotechnology viz. secondary host plants [12, 13]. 3.27(ii)]. plants include “Diglotti” (Litsea salicifolia Roxb. The non-mulberry silkworms are eri (Samia ricini), Muga (Antheraea assama), temperate tasar (Antherara myllita) and tropical tasar (Antherara proylei). it Was Also Found that Sericulture Productivity Can Be Further Increased by Planting Improved Varieties of Mulberry as it Has Been Observed that where, Very Good Quality Mulberry Leaf and Inputs Are Available, the Sericulture Productivity Is Reasonably Good. North West India, Dehradun, India, 2006, 312-315. Taxonomic studies on some of the The rearing was carried out under uniformed laboratory condition by adopting standard method at Central Sericultural Research and Training Institute, India has distinction being producer of all five type of commercially exploited natural silks viz. %PDF-1.5
Both are equally suitable for feeding the eri silkworm. Thus this species is phylogenetically less adaptive reaching its ecological isolation that is indicative of being on verse of extinction. Non-mulberry sericulture is mostly practised by the tribal and local community. It is believed that muga culture originated in the Brahmaputra Valley of Assam, India. The Primary Host plant of Muga silkworm is Som (Persea bombycina) and Soalu (Litsea polyantha). The rearing results revealed that hatching percentage was 97.47% in spring and 97.30% in autumn and shell ratio (SR %) was 22.09% in spring and 21.42% in autumn. Host plants of Muga silkworm. Influence of new host plants on. Host plant selection behavior or feeding preferences are largely mediated by the presence and distribution of secondary metabolites in plants (Frankael, 1959, Lin et al., 1998). Silk production is directly dependent on The production of bivoltine cocoons and silk in India is important to upgrade the quality and productivity of Indian silk to International grade which is yet to become a reality. This study also proves that in the near future Tasar culture will become a boon to the poor people along with Mulberry cultivation. silkworm feed on different food plants. Mulberry, Tropical tasar, Temperate tasar, Eri and Muga. 5 points Write the names of two primary and two secondary host plants of muga silkworm Ask for details ; Follow Report by Bala3167 06.12.2019 Log in to add a comment What do you need to know? Effect of different food plants on the silk percentage and effective rate of rearing of Philosamia ricini Hutt. Muga silkworm is a wild silk producing insect feeding on the leaves of som (Persea bombycina), soalu (Litsea monopetala) and dighloti (Litsea salicifolia). Based on the feeding behaviour of silkworms, sericulture can be broadly classified into mulberry and non-mulberry.
