Influence of new host plants on larval duration and total life cycle of Eri silkworm during (NovâDec and Jan-Feb ). But most of the rearer families in these villages do not have their regular plantation of food plants. region because of its profuse vegetative growth and poor yield of seeds, the leaves are utilised for production of eri cocoon only.

Biology of silkworm reared on Mikania micrantha and Ricinus communis: Mikania micrantha, a potential alternative host plant to Eri Silk worm: Mainu Devi, Pallabi Goswami, Jatin Kalita: 9786139936113: Books - Amazon.ca Another type of eri silk is "Ailanthus silk moth", refers to the host plant, Borkesseu, Ailanthus excelsa, practiced in China. Castor ISSN : 0022-1910. What are the secondary food plants of eri silkworms? Castor (Ricinus communis L.) is an economically important plant for production of industrial oil as well as used as primary food plant for rearing of eri silkworm, Samia ricini (Donovan). primary host plant of eri silkworm is cultivated in an area of about 39700 acres1. and tapioca (Manihot utilizsima Phol.) The crop is cultivated as an intercrop with ginger and turmeric and also for seed oil purpose. Muga culture Selection of host plant Muga farmers apply their traditional knowledge to identify suitable host plant for muga silkworm rearing. Eri-silkworm, Samia cynthia recini B. is a multivoltine and polyphgous insect feeding on diversified host plants among which castor is a primary host plant. Som and Soalu plants are propagated through mainly seeds. Which are the primary food plants of eri silkworm? Kumar et al. Influence of new host plants on. This process results in a silk called Ahimsa silk. These results suggest that the silkworm larvae acquire the host plant urease specifically at the end of the feeding feeding Subject Category: Techniques, Methodologies and Equipment see more details stage in order to degrade urea accumulated in the haemolymph. The eri silkworm, Samia cynthia ricini (Saturnidae), is a non-mulberry silkworm, and the larvae feed on several host plant species, including castor oil plants, cassava, ailanthus, kesseru, and plumeria. 3. Eri silkworm pupae can be harvested to provide a cost effective alternative edible oil that can be used to nutritional advantage in the food and feed industry. The eri silkworm mainly feeds on castor, kesseru, tapioca and bar kesseru and payam. Answer:Eri silkworm, Samia ricini is a polyphagous insect feeds primarily on castor (Ricinus communis Linn.). The eri silkworm, Samia cynthia ricini highly preferring castor as a host plant followed by tapioca and also the suitability of other alternative host has been found out for the continuous rearing during unseason of crop. Eri host plant. Samia ricini, or the Eri silkworm, is raised in India and parts of the Orient for its silk. leaves, was extracted with hexane. It can rear 4-5 times in a year. Samia ricini, or the Eri silkworm, is raised in India and parts of the Orient for its silk. the two most important host plants for eri silkworm though there are certain perennial tree species like kesseru and payam in north east states may serve to provide supplementary food in the off season. However, Kesseru (Heteropanax fragrans Seem) is considered as another major perennial food plant. Host plants of eri silkworm Eri silkworm (Samia ricini) is a multivoltine and polyphagous species, which feeds on diversified host leaves. The woolly white silk is often referred to as the fabric of peace when it is processed without killing the silkworm. The percentage of un-emerged cocoon was comparatively less in case of castor Acc.003 than that in other food plants.
