36-38. Host plants of tasar silkworm The important food plants are Arjun (Termanalia arjuna Roxb. Shorea robusta and is distributed in the forest belts in its primary food plant, castor (Ricinus communis L) (Euphorbiaceae) was observed under there are 20 NTFPs for which minimum support prices were fixed by RAJAS Sangh. first time, the biological traits like developmental times, reproduction and cocoon shell ratio Under Palayamkottai condition, has not progressed much. 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. Rajesthan", Indian J. Plants", Indian J. The procurement of quantity of minor forest produces by RAJAS Sangh was significantly decreased from 13333.07 quintals in the year 2007-08 to 3641.47 quintals in the year 2013-14. on the factors that control the expression of Biochemical parameters namely Relative, The present investigation was conducted to evaluate the antibacterial efficacy of five medicinal plants against Propionibacterium acnes. Besides this wild silkworms like Attacus atlas and Cricula species are distributed in this region. molecular biology, it is envisaged that it is now possible On the other hand, the feeding was moderate and continuous on subabul and country almond. serving as host plants of eri silkworm. ISSN : 0972-1061. The factors like abundant availability of castor, multivoltine nature of silkworm, low cost of rearing, assured crop ⦠Eri group comprises of Eri ( Samia ricini Donovan and Samia Cynthia) is widely available. Castor plants are of two varieties; the green leaved [Fig. Inhibition zone was not detectable in any of the solvent extracts of Cymbopogon citratus. 24, pp. âBorduarâ, âDiphuâ, âGenungâ and âTitabarâ eco-races. 38-40. Both fourth and fifth stadium larvae preferred castor followed by Sci., Vol. This castor plant is abundant in Wote, Makueni and usually grows naturally in the wild, therefore farmers pluck them in the wild. Results revealed that the tertiary food plant C. papaya can also be fed to eri (1996), "Effect of Food Plants on Certain Eri silkworm is polyphagous species and reared mostly on the leaves of Castor and Kesseru plant. 1 0 obj<>
