Eri Silkworm Rearing. In case of Calotropis gigantea, the larvae started feeding initially than stopped in a short period and showed 100% larval death with in an hour. In laboratory study we were used 10 plant species, viz., Calotropis gigantean, Nerium odourm, Leucaena leucocephla, Parthenium hysterophororum, Annona squamosa, Pongamia pinnata, Coconut leaf, banana leaf, Sesbania grandiflora, and Terminalia catapa for feeding the 5 th instar larvae of eri silk worm after pre-starvation period of 30 min. Eri rearing During early stage, the farmers rear eri silkworms in Dola, a bamboo made tray. The volumetric attributes of eri silkworm reared on different host plants were assessed by Kumar & Elangovan (2010). Eri Silkworm Philosamia ricini Hutt. Besides this wild silkworms like Attacus atlas and Cricula species are distributed in this region. one such approach that has extensively been used in 9, An attempt was made to rear the eri silkworm, Philosamia ricini on the leaves of Terminalia arjuna (Arjun) for the first time in India and reared under laboratory condition. Raising of Host plant and Silkworm Seed Production Silkworm Seed (Egg- Polu koni) is the backbone of silk industry. 2013 "Response of Castor (Ricini communis L.) The income generated to state from tendu leaves were increased while its production was decreased during the reference period. The name "eri" is derived from the Assamese word "era", which means "castor", as the silkworm feeds on castor plants. Minimum support prices were increased over the time period, it was highest for Buchanania lanzan–A followed by Buchanania lanzan–B, Dataura stramonium, Sapindus trifolatus, Pongamia pinnata, Emblica officinalis, Cassia tora, Honey, Jatropha curcus, Madhuca indica (seed), Terminalia bellerica and Madhuca indica (flower).

Saturniidae) on Five Different Host Plants", In comparison between the two sites, all the values were slightly higher in the polluted site than the control for all the ten plants and a considerable variation was observed among the four parameters where their percentage variations were considered. Host Plants of Eri Silkworm. The factors like abundant availability of castor, multivoltine nature of silkworm, low cost of rearing, assured crop … was recorded. On the other hand, the feeding was moderate and continuous on subabul and country almond. Performance of fourth and fifth instar larvae of eri silkworm, Samia cynthia The non-mulberry silkworms are eri (Samia ricini), Muga (Antheraea assama), temperate tasar (Antherara myllita) and tropical tasar (Antherara proylei). Therefore, several research projects have focused on rearing technique, machine and appliance development, textile, eri food and cosmetic products including exploitation of eri rearing waste.
