Abstract

Study was undertaken to evaluate the performance of different types of cocooning device of muga silkworm viz., Box type mountage, Plastic collapsible mountage, Bamboo Chandraki, Rotary mountage and the traditional Jali taking into consideration of the efficiency in cocooning, economic cocoon characters and convenient handling (easy to handle) as key parameters of the study. The comparative analysis of the performances of all the mountages revealed that Plastic collapsible mountage performed better results with regard to cocooning, the primary economic cocoon character which was recorded highest of 69 % as compared to Box type mountage (66 %) and the traditional Jali (63.75 %). Assessment of cocoon characters showed better performance in plastic mountage with regard to single cocoon weight (4.515 g in male & 5.514 g in female), single shell weight (0.382 g in male & 0.403 g in female) and silk ratio (8.465 % in male & 7.242% in female). Single cocoon analysis for reeling performance

Conclusion

Analysis of data revealed that Plastic collapsible mountage performed comparatively better results with regard to all the economic cocoon characters followed by box type mountage as compared to the traditional Jali though there was no significant difference among these treatments. However, Rotary mountage and Bamboo chandraki performed significantly low among the mountages. However, keeping in view of convenience of handling right from mounting of matured silkworms to harvesting of cocoons, durability, less space for keeping, easy disinfection, easy transportation and prevention of escaping worms, Plastic collapsible mountage can be recommended as a substitute of Box type mountage for cocooning of muga silkworm.
