Abstract:

Abstract

Seribiodiversity refers to the variability in silk producing insects and their host plants. The North – Eastern region of India is considered as the ideal home for a number of sericigenous insects. However, no detailed information is available on seribiodiversity of Assam. In the recent times, many important genetic resources are facing threats due to forest destruction and little importance on their management. Therefore, the present study was carried out in different regions of the state during the year 2012-2013 covering all the seasons. A total of 12 species belonging to 8 genera and 2 families were recorded during the survey. The paper also provides knowledge on taxonomy, biology and economic parameters of the sericigenous insects in Assam. Such knowledge is important for the in situ and ex- situ conservation program as well as for sustainable socio economic development and employment generation.

Dr. Tarali Kalita

International Journal of Advanced Research , 2015

Abstract:

Assam and North East India hold an unique position in the global sericulture map for its monopoly in muga culture. The muga silk is the 2nd most expensive silk in the world which is produced by the insect Antheraea assamensis of order Lepidoptera and family Saturniidae. At the present day world, phenotypic variation have been used extensively to describe the population structure in many species and is considered that it plays an important role in conservation strategies of many threatened organisms. In the present study, survey, collection and morphological characterization showed that there exist great variation in color, size and weight of various stages of life cycle of A. assamensis which indicates a higher genetic diversity among the population. Such studies may help to select a beneficial trait for future breeding program and to conduct ex-situ conservation program of the collected population in a conductive climatic condition to prevent the loss of crop failure due to adverse climatic condition.

Biodiverse , 2018

Abstract:

OBJECTIVES
• To collect the cocoon sample of Antheraea assamensis from different regions of north east India.
• To study the morphological structure of silk fibre of different population of Antheraea assamensis
• To study the mechanical strength of different population of Anthearea assamensis.



RESULTS AND DISCUSSIONS
The result showed that from the eleven collected population, the silk fibre of wild stocks have more tensile strength than the cultivated stocks. The resultant more tenacity may be due to
higher concentration of alanine and glycine in the wild stocks (Nadiger and Hallyal, 1984) But, due to higher deposition of calcium oxalate crystals the wild cocoons were hard and difficult to real. Ranking of the different population of A. Assamensis on the basis of FTIR ratio revealed that cocoons with lower degree of FTIR value indicates lower degree of mineralization and thereby forming soft cocoons. It is reported that the demineralizing agent such as Ethylendiamine-tetra acetic acid (EDTA), citric acid etc. Can be used to remove calcium oxalate by dissolving the cocoons directly into the solution (Gheysens et al., 2011). The wild stocks and some of the cultivated stocks showed tight packaging of silk fibre indicating better volume of silk fibre.

Journal of Advanced Zoology , 2018

Abstract:

ABSTRACT:

Antheraea assamensis, the producer of golden muga silk is endemic to North East India and
Brahmaputra Valley of Assam particularly. The insect represents phenotypic variabity in different stages of the life cycle. In the present study, eleven populations of muga silk worm are collected from different regions of North east India to assess the DNA polymorphism and genetic distance among the muga silkworm stocks. The extracted genomic DNA were analysed using twenty two Inter Sequence Simple Repeats (ISSR) markers of which ten primers produced 81 bands and 58 bands of them are polymorphic indicating the average percentage of DNA polymorphism 71.60%. The Jaccard similarity coefficient ranged between0.133 to 0.700 indicating high level of gentic diversity. Cluster analysis using Unweighted Pair Group Method (UPGMA) based on ISSR profile divided the eleven accessions into nine clusters. Thus, the study suggested that the population with low genetic variation are homogenous in nature whereas the high genetic variation among the population indicates that those populations have already differentiated into separate gene pool. Therefore, it is important to conserve this separate gene pool without any
inter mixing.

Journal of Advanced Zoology , 2019

Abstract:

ABSTRACT:

Sinarest syrup (0.08ml/30g BW) was orally given to swiss Albino mice (C3H/J strain) with the help of oral gavage for 14 days and 28 days. Significant decrease in weight of liver and kidney was recorded and 28 days treated mice liver showed lobule formation. The total number of red blood cells, Haemoglobin %, mean corpuscular volume and packed cell volume significantly decreased (P<0.05). Also, there was a significant increase in number of white blood cells. The serum liver enzymes (SGOT/AST, SGPT/ALT & ALP) showed significant increase indicating
destruction of hepatic cells. The serum creatinine level also significantly increased compared to the control group. The examination of Haematoxylin-Eosin stained liver sections showed focal hepatocyte necrosis, dilated central vein with infiltration of lymphocytes and hematopoietic cells around it, cytoplasmic vacuolations, pyknosis, karyolysis and karyyohexis of hepatic cells and Kupffer cell hyperplasia in the treated group. The histological changes observed in kidney include flattening of the renal tubular cells with loss of brush border, deformed and degenerated glomeruli, vacuolation and completely distorted distal tubules. Therefore, it is advised that caution should be taken with the rampant use of this drug. One should always take this drug in a recommended dose and recommended period only when prescribed by qualified medical practitioners.

Oriental Insects , 2020 , https://doi.org/10.1080/00305316.2020.1727376

Abstract:

The characterisation of cocoons is one of the most important requirements to know the economic importance of a sericigenous insect. Antheraea assamensis produces the golden muga silk, which is considered as the second most expensive silk in the world for its high quality. Although muga silk worm is a single species, it has many varieties with respect to its geographical areas. However, literary works on the most important economic traits connected to silk production of
different populations of A. assamensis are very limited. Therefore, the present study has been aimed to know the cocoon efficiency and the silk quality of the different populations of the A. assamensis following the standard techniques. The study was performed after collecting the cocoon samples from 11 different regions of the North East India. The result showed that A. assamensis exhibit variation in cocoon colour along with other significant differences in the cocoon weight, shell weight, shell ratio and silk quality. The cocoons of the wild population recorded more cocoon weight, shell ratio, filament length and tenacity but at the same time due to the deposition of higher degree of calcium oxalate crystals on the cocoon surface, they were hard to reel. Based on these characters, the study recommended some stocks, which could be
used for future breeding programme based on the genetic distance between the parents.

Peer J , 2020 , DOI 10.7717/peerj.10248

Abstract:

Insects not only play a significant role in the ecological process of nature but since pre-historic times have also formed a part of the human diet. With a still growing population and skewed demographic structures across most societies of the world, their role as nutrient-rich food has been increasingly advocated by researchers and policymakers globally. In this study, we examine the edible insect diversity and entomophagy attitudes of ethnic people in Manas National Park, a UNESCO Natural World Heritage Site, located in Assam (India). The study involved a field investigation through which the pattern of entomophagy and the attitude towards insect-eating was studied. Following this, we examined the edible insect diversity and abundance at different sampling points. A total of 22 species of edible insects belonging to fifteen families and eight orders were recorded from different habitat types. Out of these 22 species, Orthopterans showed
a maximum number of eight species followed by Hymenoptera (four), Hemiptera (three), Lepidoptera (two), Blattodea (two) and one species each from Coleoptera, Odonata, and Mantodea. Dominance, diversity, and equitability indices were computed along with the relative abundance of the insects concerning four habitat types. Aspects of the economic significance of entomophagy were also observed during the field investigation. To manage insects in the interest of food security, more attention should be given to sustainable collecting and rearing methods emphasizing their economic, nutritional, and ecological advantages.

Abstract:

Abstract:

 

Rice, the mostly used cereal grain, is composed of three layers-husk, bran and endosperm, each contains various specific components. These layers can be lost or retained depending on the different processing methods used. The objective of the present study was to know the nutritional value of raw and parboiled Ranjit rice obtained by de-husking method using both modern milling and a traditional de-husking method by “Dhenki”. After preparing the rice flour, estimation of carbohydrate, protein, crude lipid, crude fiber, Minerals: Fe, Zn, Ca, vitamins thiamin and niacin were carried out for all the rice samples following standard methods. The milled rice grains showed greater losses in the fat, protein and fiber contents compared to the rice grains de-husked by Dhenki. On the other hand, the parboiling of the paddy prior to de-husking enhanced the nutritional quality of the rice compared to the un parboiled raw rice as parboiling - allows some nutrients like Iron and vitamins to transfer from the hull into the grain. Parboiled rice also showed less carbohydrate content compared to the raw rice. Further study with animal model revealed that parboiled rice de husked by Dhenki showed slow rate of digestion indicating it as a source of good carbohydrate.The findings may be useful in helping the people to choose the right processing methods for rice to obtain maximum yield in nutrition.

Food Research , 2022 , https://doi.org/10.26656/fr.2017.6(1).080

Abstract:

India is a major producer and consumer of rice. Assam is one of the top rice-producing states of the country and is situated in the indo-Burma hotspot, it is gifted with exceptionally rich rice diversity. These indigenous rice varieties have unique properties and are cultivated by the local farmers and are only used for the preparation of traditional cousins. In the present study, four indigenous rice varieties namely Kumol saaul, Kola Bora, Kola kunkuni Joha and Khamti Lahi have been selected for nutritional profiling and bioactive compounds screening. The biochemical estimation of the nutrients was carried out following the guidelines of the Association of Analytical Chemists International. For phytochemical screening, the methanolic extract of the rice samples was prepared and qualitative as well quantitative tests were performed following standard protocols. The carbohydrate content was higher in Kumol saaul (48.3±0.34) and khamti Lahi (38.64±0.4) and therefore may be used to prepare breakfast for the farmers while working in the paddy field and to prepare traditional cousin Tupula vat respectively. The protein content was highest in Kola bora (8.9±0.02) which are used for the preparation of traditional food. Crude lipid, Crude fiber, vitamin and Mineral content also showed significant differences in the four rice varieties. The total anthocyanin content and antioxidant activity were found more in Kola Bora (328.26±0.87, 81.45±2.29) and Kola Kunkuni Joha (11.90±0.89, 67.34±1.23). Thus, the study clearly showed that these indigenous rice varieties are not only traditionally important but also a good source of nutrients and bioactive compounds. It is expected that, in-depth knowledge of nutrients and other bioactive compounds in the rice varieties may be beneficial for their promotion in global the market as well as germplasm conservation.

Journal of Insects as Food and Feed, , 2022 , https://doi.org/10.3920/JIFF2021.0141

Abstract:

Insects as food have been consumed all over the world, mostly by ethnic communities, since time immemorial. With the ever-increasing human population causing an imbalance between food production and nutrition, edible insects are gaining importance as an alternative food source. The aim of this paper is to record the region-specific current practices of entomophagy and their implications in food security. The study involved field investigation to find out the pattern of entomophagy among the scheduled tribes of the Bodoland Territorial Region (BTR), Assam. Following this, we made an effort to estimate the diversity of edible insects at different sampling sites in the studied area. Nutritional profiling of some of the edible insects was carried out to know their potential as a measure of food security. A total of 25 edible insects belonging to 9 orders and 18 families were recorded during the study period. Species diversity was recorded highest in forest/backyard forest habitat followed by agricultural field habitat, open field habitat and swampy area habitat in all the four districts in BTR, Assam. During the consumer survey, a total of 4,051 people belonging to four different scheduled tribes, Bodo, Rabha, Garo and Sarania were interviewed and out of them, 3,840 (94.79%) people were found to consume insects as food. The insects are mostly consumed in fried form, followed by smoked, raw, paste, roasted and curry form. The biochemical analysis of nutrient contents of 11 commonly consumed edible insects showed that they are a rich source of protein, vitamins and micronutrients with a reasonable amount of carbohydrates and lipids with higher radical scavenging activity. To manage insects in the context of food security, increased attention should be given to sustainable collection and successful farming of edible insects for the creation of export potential, giving emphasis on the nutritional advantages.
