Abstract

Author-written

Mountages serve as essential devices for providing platforms on which mature silkworms spin their cocoons. Farmers employ different mountage types, often utilizing locally available materials, though each has specific limitations. The present study evaluated five mountages Rotary Collapsible, Mulberry Twig, Egg Tray, Paddy Husk, and Pinus for their impact on cocoon and post-cocoon parameters. Results revealed that Paddy Husk Mountage produced the highest single cocoon weight and maximum average filament length (93.33), whereas Rotary Collapsible Mountage recorded the lowest. The non-breakable average filament length was highest in Pinus Mountage (78.66) and lowest in Rotary Collapsible Mountage (71.33). In terms of average filament denier, Rotary Collapsible Mountage showed the highest (2.61) while Pinus Mountage exhibited the lowest (2.33). Based on cocoon quality and post-cocoon traits, Paddy Husk Mountage emerged as the most effective, being inexpensive, widely available, and superior in performance compared to other mountages.

Introduction

Sericulture is the scientific practice of silk production through the rearing of silkworms, primarily Bombyx mori L. Due to its luster, softness, strength, and durability, silk is regarded as the "queen of textiles." Mulberry sericulture involves mulberry cultivation, silkworm rearing, cocoon production, reeling, and weaving. Although sericulture originated nearly 5000 years ago in China, it continues to play an important agro-industrial role worldwide. In Jammu and Kashmir, sericulture is practiced in 20 districts, with Anantnag, Kupwara, Pulwama, Baramulla, Ganderbal, Udhampur, Rajouri, Reasi, and Kathua as major production areas. Despite favorable climatic conditions, productivity remains low due to factors such as limited leaf availability, poor hybrid performance, technical constraints, and low farmer awareness. Research and extension agencies including SKUAST, CSB, CSRTI Pampore, and RSRS Miran Sahib are working to address these challenges and promote sericulture development in the region. Among the different stages of silkworm rearing, cocoon spinning is critical. It begins with the transfer of mature larvae to cocooning devices called mountages, where they spin cocoons through continuous head movements. The quality of cocoons depends heavily on the type, structure, and design of mountages. Poor mounting practices, improper density, or substandard mountages often result in inferior cocoons and reduced raw silk yield. Thus, selection of suitable mountages is essential for ensuring high-quality cocoon and silk production.

Material and Method

The present study was designed and will be executed at post graduate department of Sericulture Poonch Campus University of Jammu.Material to be used: Silkworm bivoltine hybrid:-Fc1×Fc 2 Data analyzed by ANOVA (analysis is variance) Procurement of live material and type of seed Silkworm hybrid strain FC1 X FC2 was procured from the State Sericulture Department, Mendhar for the present investigation. After incubation of eggs at 25±1°C and relative humidity of 80±5%, black box was carried out on 8th day to achieve uniformity in hatching. The larvae hatched from the loose eggs were reared separately under uniform laboratory conditions as described by Yokoyama (1963) and Krishnaswami (1978). Area of study The present investigation on effects of mountage types on silkworm Bombyx mori spinning FC1×FC2 was conducted in Department of Sericulture, Poonch Campus, and University of Jammu.

Result and Discussion

The results on the present investigation entitled "Effect of Mountages Types in Silkworm Spinning" (FC1 X FC2 Silkworm hybrid). The experimental result showed that there were significant changes in the growth, development and economical attributes of silkworm due to different mountages.

Discussion

The final stage of the rearing process is mounting. Mounting is the process of transferring adult fifth instar larvae to mountages. When larvae reach full maturity, their bodies become translucent, they stop feeding, and they begin looking for a suitable location to attach themselves for cocoon spinning and pupation. These actions plainly suggest that the developed larvae should be transferred into the mountages. They are collected and placed on mountages. The worms hook themselves to the mountages' spirals and begin spinning the cocoon. Silk fluid is discharged in minute amounts as the head moves, hardening to form a long continuous strand. The silkworm first builds the framework for the cocoon structure by weaving a preliminary web that gives the larva a place to stand while spinning the compact cocoon shell. The silk filament is deposited in a succession of brief waves producing the figure of eight due to the head's unique movements. Layers are constructed and added in this manner to form the tight cocoon shell. The shrinking larva wraps itself around the cocoon's compact shell and detaches from it, transforming into a pupa or chrysalis. Multi-voltine cultivars need 2-3 days to spin, whereas uni and bivoltine variants take 3-4 days. Mountages are essential for producing high-quality cocoons. Farmers rely on local resources and employ various types of materials to construct Mountages. The quality of a cocoon is determined by the materials used, the finishing of Mountages, the space available for spinning worms in Mountages, and other factors. Narrow space affects ventilation and results in poor reliability of cocoons. Similarly more space results in wastage of silk in the form of floss (Manual on Mountages, Mounting and Harvesting Technology for Quality Coon Production by Mathur and Quadri, (2010) [42] .

Our study showed that the single cocoon weight was recorded highest inthe Paddy Husk Mountages ( [33] , Shinde et al., (2012) [31] , and Ademola et al., (2014) [1] did comparable experiments on mountages and found similar results.

Summary and Conclusion

Mountage is a mechanism that allows mature silkworms to spin cocoons on a platform. At the field, there are several sorts of mountages, some of which are more popular. Farmers construct such mountages out of a variety of locally accessible materials. According to previous research, the type of material utilized, as well as the design and construction of the mountage, will determine the quality of the silkworm cocoon, Bombyx mori L. In addition to providing support for spinning worms, mountages should meet the following requirements: providing a convenient and uniform space with appropriate dimensions for spinning good sized cocoons, preventing the formation of double and malformed cocoons, providing ventilation for drying up the worm's last excreta prior to spinning, and allowing easy mounting and harvesting. Narrow area limits ventilation for spinning larvae, resulting in poor cocoon reelability; larger room, on the other hand, wastes silk in the form of floss used by the silkworm to build foundation for cocoon formation. (Mathur and Qadri, 2010) [42] . Improper mounting structure and careless handling and maintenance of mature silkworms result in the creation of faulty cocoons, resulting in a loss of 5 to 8% of cocoon output. As a result, the In conclusion, the Paddy Husk mountage employed in this study is the best for silkworm rearing, because it is easily and locally available in everywhere in the villages as well as town. The cost of the Paddy Husk was very low and quality of cocoon formed by Paddy Husk mountage is very good cocoon and the post cocoon parameters. The result of the present study reveals that, the Paddy Husk mountage is the better when compared to the other mountages for various parameters such as cocoon and the post cocoon parameters viz., total number of cocoon and their weight of good cocoon per mountage. Similarly, number of defective cocoon per mountage was found least on Paddy Husk mountage than egg tray mountage. The cocoon production is the end product of silkworm rearing before transferring to textile industry. The quality and quantity of cocoon produced is very essential to every Sericulturist. Paddy husk mountage exhibit the highest cocoon quality and quantity among the parameters measured. Although the Paddy husk mountage has some demerit in terms of biodegradation and sticking to the shell of the cocoon. All needed precaution are needed to put into Consideration to get optimum quantity and quality of cocoon. It is therefore been recommended that sericulturist should explore the use of paddy husk mountage which are readily available in their environment. The main objective of the sericulture is the production of large quantity of good cocoon which in turn result in production of good quality of silk. This cannot be obtained only by the use improvement of mulberry cultivation and silkworm rearing, but also by the method of mounting and mountages used (Singh et al., 2012) [4] . Therefore, the present study was conducted "To investigate the effect of different mountage on spinning of cocoon" obtained from the Paddy Husk mountage in comparison to with the control and showed that, the Paddy Husk mountage exhibited better results when compared to the Mulberry twig mountage and Rotatary collapsible mountage. However, subsequent studies are needed to verify as which of these Paddy Husk mountage would be the best mountages to release into farmers field.
