Four pure bivoltine silkworm breeds SK6, SK7, BCon1 and BCon4 were evaluated under Uttar Dinajpur agro climatic (Raiganj) conditions West Bengal in two different crop seasons along with their mean performance. The cocoon and associated parameters of the breeds were documented and utilized for analysis of and multiple trait evaluation indexes were valued. The present study revealed that there are considerable variations in the cocoon and associated traits among the studied breeds. However, the breed SK7 found to be the best among studied breed and scored average EI values >50 for the maximum of four individual traits viz., fecundity, single cocoon weight, shell weight, shell ratio, particularly with respect to overall performance irrespective of seasons.
Economic Analysis of Silkworm Rearing and Cocoon Production in Bilaspur District of Himachal Pradesh
Economic Affairs, 2019
Sericulture is an agro-based multitudinous activity which involves cultivation of mulberry, production of laying, rearing of silkworms for cocoons, marketing and reeling of cocoons for value added products such as processing and weaving of the yarn. It is a short gestation period labour intensive enterprise which can go a long way in promoting inclusive growth and alleviating poverty in rural areas. The present study was therefore carried out in order to analyse investment and returns pattern of cocoon production in Bilaspur district of Himachal Pradesh. Two-stage random sampling and proportional allocation method was used to prepare a list of sample farmers. Out of 60 silkworm rearers, 19 were large and 41 were small. The dry cocoon production per farm on small and large category was estimated at 8.25 kg (6.20 kg in spring and 2.05 kg in autumn) and 19.51 kg (16.67 kg in spring and 2.84 kg in autumn). The dry cocoon production per ounce of seed was found to be 20.28 kg and 26.14 kg on small and large category households for both the seasons together. The fixed cost of production / ounce for spring crop varied from 9.92 per cent on small farms to 14.75 per cent on large farms. The variable cost varied from 90.08 per cent on small farms to 85.25 per cent on large farms implying the economical use of fixed and variable resources by large growers. The gross returns per ounce seed basis ranged between ` 1,626 and ` 5,535 on small and large farms for the spring crop. The autumn crop was found to give negative returns; therefore farmers should be provided with technology which could reduce the moisture in the rearing room, develop humidity resistant races of silkworms as well as develop varieties of mulberry plantation which may yield good leaves just after rainy season. Highlights m Due to high humidity in the areas and less time available with the rearers to seriously perform sericulture activities output of cocoons in autumn is less which results in negative return in autumn season. m Silk worm seed was the most important variable in affecting the cocoon production.

Three new Multi x Bi combinations M.Con.4 x (SK6 x SK7), M.Con.4 x NB4D2 and Nistari x (SK6 x SK7) were studied in five seasons i.e. during the period of 18 th June-12 th July, 30 th August-23 rd September, 3 rd November-2 nd December, 29 th January-2 nd March and 30 th March-25 th April with one control Nistari x NB4D2 considering nine reeling characteristics along with shell percent and cocoon yield per 100 disease free layings (DFLs) to establish the seasonal effect on all the parameters. Results reveal that all the characters performed well in November-December. Highest yield per 100 DFLs was recorded during November-December in all combinations showing >60 kg yield. Higher correlation of yield/100 DFLs with filament length, non-breakable filament length, denier, raw silk percent, reelability percent and recovery percent was recorded in all combinations of Multi x Bi considered in this study. Variability observed among four combinations indicates the effect of different temperature and humidity of different seasons on expression of different traits. The results indicate that there is significant relationship of raw silk percent with reelability percent, recovery percent and evenness. Reelability percent showed higher correlation with recovery percent. It was observed that neatness was positively correlated with evenness. The overall performance of the newly evolved combinations with regard to productivity and reeling characteristics is discussed emphasizing their utilization at commercial level.

Tasar culture is being practiced in Maharashtra since last 200 years by the tribal folks of four eastern districts of the state. However, the productivity of tasar cocoons in the state is hovering around average of 2000-4000 cocoons/100 Dfls (Disease Free layings) throughout the year against the norm of 6000 cocoons which might be due to the non-adoption or low adoption of improved tasar rearing technologies by the tasar silkworm rearers. Thus, present study was conducted to investigate the impact of adoption of improved tasar silkworm rearing technologies as a strategy for improving tasar cocoon production in the state. For the study, an “Ex Post Facto” research designed was used and 50 adopted seed cocoon rearers and 50 non-adopted seed cocoon rearers were selected through random sampling method. The results of the study showed that, during the Ist Crop of Daba TV rearing, the average cocoon yield of the farmers who have adopted the tasar silkworm rearing technologies ranged from ...

The study conducted “Analysis of constraints on production and marketing of tasar and mulberry silk in Chhattisgarh” included four districts i.e. Bastar, Korba, Jashpur and Raigarh. In each district one block, from Bastar district Jagdalpur block, Jashpur district Kansabel block, Korba district Korba block and Raigarh district, Dharamjaigarh block has been selected for the study based on maximum tasar and mulberry seed centres and 16 villages has been selected for the study, information about the primary data was collected from 160 cocoon growers in selected areas, though well-prepared interview schedule/ questionnaires. The study observed that tasar and mulberry cocoon grower and their marketing was found to be major constraints unavailability of labour during the production process was ranked first according to measurement, respectively silkworm, lack of knowledge in the maintenance of host plant, unavailability of the good quality plantation, lack of technical guidance, unavailab...
ISSUES FACED BY COCOON PRODUCERS IN ANANTNAG DISTRICT
THE JOURNAL OF ORIENTAL RESEARCH MADRAS, 2024
Since the introduction of sericulture in Anantnag district of J&K has long history but the industry is still in extremely infant stages despite the supposedly multi-fold potential. Information on challenges faced by the cocoon producers were divided into three categories Climatic problems, Non-Climatic and Market issues and was gathered from randomly sampled respondents through live interviews and filled questionnaires. It was established that, currently the industry is characterized with insignificant cocoon production volumes that cannot sustain the local and international market. Silkworm rearing is mostly practiced particularly by the small and marginal farmers comprised mainly of women and youth as a measure to alleviate poverty. Often the quality of cocoon and silk yarn is low resulting from poor agricultural, silkworm rearing and cocoon reeling technologies. Preliminary data gathered revealed that farmers mainly face the following challenges it was found out in climatic problems nonseasonal rainfall or non-seasonal temperature, pest attacks due to high rainfall was halting cocoon production and in Non-climatic problems lack of basic and advanced technology, non availability of skilled labours, high cost of technology is main hindrance faced by cocoon producers of Anantnag. In market issues information about market prices was main problem that was faced by cocoon producers in Anantnag district. Cocoon producers are also facing the non-availability of rearing house and nonavailability of rearing equipment facilities.
Host Plant Management Strategies for Quality Tasar Seed Cocoon Production
PLANT ARCHIVES
The tropical tasar silkworm, Antheraea mylitta Drury (Lepidoptera: Saturniidae) a polyphagous insect, distributed in majority of the agro-ecological conditions in India with varied phenotypic, physiological and behavioral characters. Tropical tasar has special significance owing to its potential in providing self-employment to these marginal farmers. Presently projected tasar raw silk production target is 3840 MT and by 2030 it is anticipated to be 6000 MT, the base of sericulture industry is the seed sector and production of quality dfls which in terns comes from quality cocoons and is vital aspect in tasar silk industry. Majority of silkworm rearing happens in conventional forest patches (natural habitat) where constraints like exposure to predators, parasites, diseases and natural vagaries are prominent. The present average rearing capacity is around 150-200 dfls/ha and the productivity ranges from 30-35 cocoons/dfl with a success rate of 15 to 20%. Quality tasar seed cocoon production depends upon successful management of host plant as the nutritional status of food plant plays a pivotal role on silkworm life cycle and its reproductive potential. The swift progress in technologies adoption like preparation of farmland, high yielding host plant lines, harnessing potential of alternate primary food plant like Lagerstroemia speciosa, nursery raising techniques, separate chawki garden and planting procedures (proper spacing), following calendar of activities for maintenance of host plant, protection of host plants from pest and disease through recent interventions, farm mechanization, integrated farming practices, application of organic inputs are required for improvement of quantity and quality of leaf. The adoption of proper management approaches improves the water use efficiency, soil health status, leaf nutrient quality, lower pest load thereby increasing the rearing capacity upto 250 dfls /ha with an average yield of 45 to 50 cocoons/dfls in-turn making the venture more productive and remunerative.
