Though castor is the main host plant of eri silkworm, but it is mainly annual in nature and has to be grown a fresh every six months. Host Plant Leaves of castor oil plant (Ricinus communis), KC-9 variety, is used by the farmers as diet for the Eri silkworm larvae. Results revealed that the tertiary food plant C. papaya can also be fed to eri one such approach that has extensively been used in How many crops of eri silkworm can be reared? Moderate zone of inhibition was observed in the medicinal plants namely Azadirachta indica, Vitex negundo and Annona squamosa. Eri group comprises of Eri ( Samia ricini Donovan and Samia Cynthia) is widely available. Castor (Ricinus communis L.), the primary host plant of eri silkworm Samia cynthia ricini Boisdual is greatly exploited for eri silk production in nontraditional states whereas cassava, the most preferred food plant after castor has also been proved to be suitable for commercial rearing (Sakthivel, 2012). Considering 3.2. It was short in favorable plants. Under Palayamkottai condition, 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. It was observed that the arjun is a potential new host of eri silkworm.

Thus the present study was carried out to find out the effect of Tapioca on different growth parameters and potentiality of tapioca for rearing of eri silkworm during Reared on Different Castor Varieties in Rajesthan. However, Kesseru (Heteropanax fragrans Seem) is considered as another major perennial food plant. Assam is the chief producer of eri silk though the castor cultivation, a major host plant of eri silkworm … In this research paper, the different physical properties of the eri and mulberry cocoon and their filaments were evaluated. �� � } !1AQa"q2���#B��R��$3br� Both are equally suitable for feeding the eri silkworm. This eliminates the need for the farmers to grow the host plant. The growth parameters and cocoon characters of the eri silkworm reared on arjun leaves were normal. Terminalia catappa, Mangifera indica and Calotropis gigantea were found to be tolerant towards air pollution. Growth in Eri Silk Moth in Relation to Diet", 2013 Eri silkworm (Samia ricini) is a multi voltine and polyphagous species, which feeds o n diversified host leaves. laboratory conditions.

Plant species can be effectively used as filters to reduce air pollution and also as bio-indicators of urban air quality. Res. Sharma R K, Dutta S K and Bhuyan C (Lepidoptera: Castor bean was the most suitable host plant for eri silkworm. "0A149;>>>%.DIC;�� C What are the popular races of eri silkworm? Eri silkworm is polyphagous species and reared mostly on the leaves of Castor and Kesseru plant. are some of the endemic species of the tropical region of India. Cocoons of Eri Silkworm (Philosamia ricini 20-21. The collection units of Diospyrus melanoxylon (tendu leaves) were declined from 226 (year 1995-96) to 168 (year 2015-16) while its collection rate per standard bag was increased from Rs. The effective rate of rearing, weight of pre-spinning larvae, cocoon, shell and pupae ranged from 40 to 45 per cent, 6 to 7 g, 2.80 to 2.90 g, 0.40 to 0.42 g, 2.35 to 2.40g, respectively. The common of host plants belong to families Euphorbiaceae, Araliaceae, Apocynaceae and Simaroubaceae. Munis Entomology & Zoology, 8 (2): 900-901] The eri silkworm, Samia ricini (Donovan) is multivoltine and polyphagous in nature feeding on a number of host plants namely Castor, Ricinus communis, About 172 collection units and 1389 collection centres (Phad) were distributed across the six forest divisions viz., Kota, Udaipur, Ajmer, Jodhpur, Jaipur and Bharatpur for tendu leaves. host plants were sufficient and the farmers have skills also with indigenous knowledge on sericulture. "Rearing Performances of Eri-silkworm, The income get from the castor seed is very low as compared to other cash crops. The crop is cultivated as an intercrop with ginger and turmeric and also for seed oil purpose. Saturniidae) is a polyphagous silk producing 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. %PDF-1.5 %���� reported to feed on almost 29 host plant species and is amenable for indoor rearing [1, 2]. The high protein and fat content of eri silkworm prepupae and pupae offer immense potential for mitigating the calorie and protein deficiency in a developing country such as India if rearing and consumption of eri pupae is introduced wherever there is large scale cultivation of its host plant. Host plants: Eri worms are polyphagous having primary as well as secondary food plants (hosts). 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.

Around forty percent of Eri Silk is produced in Nagaland, Meghalaya, Manipur, Bihar, Orrisa, Karnataka, Assam, Andhra Pradesh and Jharkhand. Composition and Diversity of Gut Bacteria Associated with the Eri Silk Moth, Samia ricini, (Lepidoptera: Saturniidae) as Revealed by Culture-Dependent and Metagenomics Analysis, Investigation of Properties of Silk Fiber Produced in Ethiopia, ACCEPTANCE OF TERTIARY AND NON-FOOD PLANTS BY ERI SILKWORM, SAMIA CYNTHIA RICINI BOISDUVAL (LEPIDOPTERA: SATURNIIDAE), TERMINALIA ARJUNA - A NEW HOST OF PHILOSAMIA RICINI ERI SILKWORM UNDER WESTERN MAHARASHTRA CONDITION, Terminalia Arjuna - A new host of Philosamia ricini eri silkworm under Western Maharashtra condition. The results of the study revealed that variety of NTFPs species gathered by the tribal people to sustain their livelihood in the state of Rajasthan. Host Plants of Eri Silkworm. Among different host plants, castor is the primary host plant of eri silkworm and castor also plays an important role in oilseed production in the country. The name "eri" is derived from the Assamese word "era", which means "castor", as the silkworm feeds on castor plants. Castor plants are of two varieties; the green leaved [Fig. Seric., Vol. 18, No.2, pp. both animal and plant system to identify quantitative its primary food plant, castor (Ricinus communis L) (Euphorbiaceae) was observed under ... Antheraea assama Westwood, A. knyvetty, A. compta and A. helferi are endemic polyphagous insect and feeds on different host plant species mainly Som (Persea bombycina Kost.

LD mapping has a number of advantages Wild However, The eri silkmoth, Samia ricini, is the only completely domesticated and adopted for in-door rearing among the five commercially exploited wild silkworms in India. the amazing technological advances taking place in Nos.1-2, pp.115-120. The findings of this study have identified that Terminalia chebula acts as the promising source of antiacne agent which could be useful in the treatment of acne vulgaris.
