Abstract:

Silk protein sericins, in the recent years, find application in cosmetics and pharmaceuticals and as biomaterials. We investigate the potential of sericin, extracted from both mulberryBombyx moriand different non-mulberry sources, namely, tropical tasar,Antheraea mylitta; muga,Antheraea assama; and eri,Samia ricini,as growth supplement in serum-free culture medium. Sericin supplemented media containing different concentrations of sericins from the different species are examined for attachment, growth, proliferation, and morphology of fibrosarcoma cells. The optimum sericin supplementation seems to vary with the source of sericins. The results indicate that all the sericins promote the growth of L929 cells in serum-free culture media; however,S. ricinisericin seems to promote better growth of cells amongst other non-mulberry sericins.

Abstract:

The protease released by Pseudomonas aeruginosa strain AC-3, a causal organism of flacherie disease in Antheraea assama Westwood silkworms, was characterized and its activity against muga silkworm larvae was assessed in laboratory studies. When grown in casein broth maximum protease production occurred when the strain was cultivated for 60 h. This protease was partially purified by acetone precipitation and subjected to SDS-PAGE. Its molecular weight was approximately 35,000 da. The partially purified protease reduced larval survivability in vivo. The hemolymph protein profile revealed an apparent detrimental effect of the protease on biologically important proteins of silkworm larvae.

Abstract:

Persea bombycina King, (Som) and Litsea monopetala, (Soalu) are grown abundantly for rearing of Muga Silkworm Antheraea assama for production of lustrous golden muga silk in North Eastern Region particularly in Assam. Package of practices for propagation and raising of systematic plantation of both the species have been developed and adopted by the farmers ar large scale. Plants become ready for silkworm rearing after 3 years of plantation. To provide additional income, regular cultural practices and to increase production and productivity per unit area an experiment was conducted at Regional Muga Research Station, Boko in lower Assam by cultivating intercrops both in Kharif and Rabi seasons during the years 1996 to 1999 in Soalu plantations raised in 3x3 and 4x4 metre spacing. Net return per acre from intercrops in both spacing has been worked out. The effect of intercrops on plantations has also been studied through leaf yield and its contributing characters. The study reveals that Cucumber in kharif season and Brinjal in rabi season are most remunerative in both spacing. Intercropping helps in increase in leaf yield to the tune of 135 kgs per acre in 3x3 metre and 192.5 Kgs per acre in 4x4 metre spacing during gestation period.

Abstract:

Food-derived bioactive peptides (BAPs) obtained from edible insect-protein hold multiple activities promising the potential to target complex pathological mechanisms responsible for chronic health conditions such as hypertension development. In this study, enzymatic protein hydrolysates from non-mulberry edible silkworm Antheraea assama (Muga) and Philosomia ricini (Eri) pupae, specifically Alcalase (A. assama) and Papain (P. ricini) hydrolysates obtained after 60 and 240 min, exhibited the highest ACE-inhibitory and antioxidant properties. The hydrolysates’ fractions (<3, 3–10 and >10 kDa), specifically Alc_M60min_F3 (≤3 kDa) and Pap_E240min_F3 (≤3 kDa), showed the highest antioxidant and ACE-inhibitory activities, respectively. Further RP-HPLC purified sub-fractions F4 and F6 showed the highest ACE inhibition as well as potent anti-oxinflammatory activities in lipopolysaccharide (LPS)-treated endothelial cells. Indeed, F4 and F6 ACE-inhibitory peptide fractions were effective in preventing p65 nuclear translocation after 3 h of LPS stimulation along with the inhibition of p38 MAPK phosphorylation in HUVEC cells. In addition, pretreatment with F4 and F6 ACE-inhibitory peptide fractions significantly prevented the LPS-induced upregulation of COX-2 expression and IL-1β secretion, while the expression of NRF2 (nuclear factor erythroid 2-related factor 2)-regulated enzymes such as HO-1 and NQO1 was induced by both peptide fractions. The derived peptides from edible pupae protein hydrolysates have potentialities to be explored as nutritional approaches against hypertension and related cardiovascular diseases.

Abstract:

Persea bombycina Kost is a primary food plant of Muga silkworm, Antheraea assama Ww. Phenotypic and genotypic variability were studied in eight genotypes of Persea bombycina Kost for rooting percentage and their five contributing characters. A wide range of phenotypic variability was observed for rooting percentage, number of primary roots, number of secondary roots, length of the longest root, average length of the root and survivability. In different genotypes number of secondary roots gave highest estimate of genetic coefficient of variation followed by number of primary roots. Estimate of heritability was high in all the traits. Estimate of genetic advance was high in number of secondary roots, survival percentage and number of primary roots. Rooting was significantly correlated with number of primary and secondary roots, length of the longest root and survival percentage both at the phenotypic and genotypic level. The other characters were also significantly correlated to each other.

Abstract:

Moisture content of the harvested Som leaves plays a vital role in successful indoor rearing of muga silkworm Antheraea assama. Considerable delay is noticed between harvesting of leaf and feeding to silkworm during Chotua (February to March) and Aherua (June-July) muga seed crops during indoor rearing. After harvest, the leaves lose their moisture gradually. The loss of moisture during 9.00 A.M. to 4.00 P.M. was determined in the 8 morphotypes of Som (Machilus bombycina). The loss of moisture was least (6.19%) in morphotype M (5) and maximum (24.75%) in M (1), in others it was 9.12% in M (2); 10.57% in M (3); 7.88% in M (4); 6.12% in M (6); 6.36% in M (8) and 7.04% in M (7). Hence M (5) morphotype is recommended for the use in indoor rearing of muga silkworm. Significant differences were also observed among these morphotypes with regard to the leaf area and stomatal numbers. The morpho-anatomical features of the leaf were found to influence the degree of loss of moisture from the leaves.

Abstract:

The Muga silk (Antheraea assamensis) rearing is confined to the North-East India, particularly, the Brahmaputra valley of Assam. This is perhaps, due to pleasant climatic conditions and distribution of wide range of muga host plants in this region. In Assam ‘Som’ tree provides the principal food for muga silkworms which produce the golden coloured silk that is very specific and prestigious to north-eastern states of India and found nowhere else on the globe. The north-eastern region of India, with total geographical area of 3,04,426 sq km, is situated in eastern part of India. It lies between 21.33 to 29.28° N. latitudes and 89.42 to 97.24° E. longitudes. The region is a part of eastern Himalaya biodiversity hotspot in the world hence endow with endemic flora and fauna. In this paper the researcher tries to the possibility of traditional way of rearing of muga, rural livelihood and conservation effort among the indigenous communities of the Brahmaputra valley in Assam.

Abstract:

Lepidopteran muga silkworm Antheraea assamensis belonging to Saturnidae is an economically important insect geographically endemic to Assam and the northeastern region of India. Like any other insect species, oviposition is one of the most vital aspects of A. assamensis as it allocates the majority of its energy during its lifecycle. Muga silkworm seed production technology has still not been studied much in detail. The demand for silkworm seeds rises during the commercial rearing season in the region, Central Silk Board has established seed production centres to cater for the demand of the sericulture industry. The number of seed cocoons processed for commercial seed production is 1.5-2.5 lakhs per annum. Muga silkworm emergence pattern is asynchronous, no. of male and female moths is not equal during operations. A. assamensis is nocturnal in habit, and emergence and coupling take place at night. Due to the asynchronous pattern of emergence, it is quite often that female moths run out of mates in the seed production centres. Due to the depleting number of potential male mates, the mating will be done mechanically by putting male female moths in a bamboo box to save the time and energy of silk moths. So, an experiment was conducted to study the difference in fecundity between naturally mated and mechanically mated muga silkworms and its impact on mating duration at Silkworm Seed Production Centre, Kaliabari, Boko, Assam during commercial crop (April-May & Oct-Nov) of 2023. The results of the study showed that maximum fecundity was observed in silkworms which are naturally mated with 214±12.08 eggs per female. Whereas, the mechanically mated muga silkworm females showed slightly less fecundity compared to naturally mated females with 203.2±12.77 eggs per female. The results on egg retention showed a clear difference with 18.6±4.77 and 16.6±8.64 eggs per female in natural and mechanical mating, respectively. The slightest reduction in fecundity and increased egg retention in female moths might be due to the impact of mechanical mating on mating duration which reported only 5.5±1.29 hrs, whereas natural mating facilitated a higher mating duration with 8.2±1.30hrs, respectively. This study showed the significance of mating type (natural and mechanical) and its impact on fecundity and egg retention of muga silkworm.

Abstract:

Four diploid som genotypes viz., PB003, PB004, PB005, and PB006 along with four polyploid counterparts viz., PB009, PB010, PB011, and PB012 were evaluated through rearing of Muga silkworm from brushing till spinning during spring and autumn seasons under the agro-climatic conditions of Jorhat, Assam. Observations on leaf yield per plant, parameters for rearing performances and biochemical constituents such as crude protein, crude fiber, total carbohydrate, reducing sugar, total soluble sugar and moisture content were made. The results revealed that tetraploid som genotype namely PB012 is comparatively superior than other genotypes.

Abstract:

Muga silkworm (Antheraea assamensis Helfer), renowned for its natural production of prized golden silk, is native to Assam and adjacent regions in North-Eastern India. However, outdoor rearing of Muga silkworms exposes them to environmental fluctuations year-round, resulting in significant crop losses due to insect pests. Notably, pre-seed crops (Aherua and Jarua) and seed crops (Chotua and Bhodia) experience significantly higher losses compare to commercial crops (Jethua and Kotia). This paper presents a thorough analysis of insect pests impacting Muga silkworm rearing, classified according to activity periods and intensity of attacks. Primary insect pests include Exorista sorbillans (Uzi fly), Apanteles glomeratus (Brachonid fly), ants and wasps. Uzi fly inflicts damage during winter (November to February), primarily affecting 4th and 5th instar Muga larvae, leading to substantial losses during cocoon harvest in March-April, jeopardizing seed production for subsequent Jethua (April-May) commercial crops. Apanteles glomeratus and ants pose threats during summer. Vespa orientalis (wasp) causes damage to late instars from April to September. Chemical control methods are discouraged due to their adverse effects on silkworms. Therefore, urgent research into environmentally sustainable pest management strategies tailored to Muga rearing's specific needs and limitations are warranted. This review synthesizes detailed descriptions of identified pests, challenges in insect pest management, and discusses various mitigation strategies, offering insights into the biology of major insect pests affecting Muga silkworms and evaluating the effectiveness of different pest management approaches.

Abstract:

Muga silkworm is multivoltine and primarily feeds on two primary food plants Som (Persea bombycina King. syn. Machilus bombycina) and Soalu (Litsea polyantha Kost. syn. Litsea monopetala). Muga silkworm Antheraea assamensis (n=15) is a semi-domesticated silk moth mentioned in literature as early 1662 BC. In its annual life cycle there are six crops of cultivated muga silk worm whose nomenclature is based on the local Assamese names of month. By virtue of the narrow ecological distribution of host food plant Antheraea assamensis is confined to only Assam and North East state of India. Empirical observations show that the population is declining due to depletion of natural habitat and lack of genetic variability among population. The wild muga silkworm which is tri or tetra voltine in nature is also found nearby forest area of human habitat in different host plant in N E state of India. A stock of wild muga silkworm collected from the nearby area of Nongpoh and Mendipathar Meghalaya. reared and maintained in muga farm and grainage activities of both wild and cultivated muga were conducted for comparative study. Details of morphology, economic characters and disease occurrence of wild and cultivated muga was studied for future improvement and breed development and also for future strategy of muga silkworm. The morphology of wild muga silkworm are little variant than cultivated muga and economic characters i.e. fecundity of wild muga was recorded 220 - 227 nos. in against the fecundity of cultivated muga observed 120-170 nos. and one gram total numbers of egg contain 120 -135 nos in wild muga in against 134 -145 nos.in cultivated muga. Average cocoon weight wild muga cocoon is ♂= 5.80 g & ♀= 6.60 g in against average cocoon weight ♂= 5.10 g & ♀= 5.54 g in cultivated muga silkworm. Average shell weight ♂= 0.51 g & ♀= 0.60 g in wild muga silkworm and average shell weight ♂= 0.43 g & ♀= 0.51 g in cultivated muga silkworm were recorded. Study revealed that the fecundity, weight of eggs, cocoon weight and shell weight are higher in wild muga silkworm than cultivated muga silkworm. Thereafter it is found that only protozoon disease was reported in wild muga silkworm and other disease i.e. Flacherie, Grasserie, Muscardine was not reported in wild muga silkworm. The mono race muga have no high yielding breed or hybrid and hence breeding programme between wild and cultivated muga may be carried out to get more heterosis, vigourity and yield enhancement.
