Influence of environmental conditions and technological innovations on silkworm performance and silk yield

Abstract

Environmental conditions and rearing practices play a crucial role in shaping the physiological performance and cocoon characteristics of the silkworm Bombyx mori. The present study provides an in-depth analysis of how key environmental parameters—temperature, humidity, ventilation, and light—collectively influence larval metabolism, growth rate, and cocoon formation. It identifies the ideal ranges of these factors required at different developmental stages and evaluates the effectiveness of modern rearing technologies in improving both silk yield and fiber quality. The importance of nutrition, with particular emphasis on the quality and freshness of mulberry leaves, is also assessed for its impact on cocoon structure and filament robustness. Case examples from major sericultural regions further illustrate how these principles can be applied under practical field conditions. The findings emphasize the need to blend advanced technological tools with established sericulture practices to ensure sustainable production and superior-quality silk. This study provides valuable direction for researchers, practitioners, and policymakers seeking to enhance silkworm performance through optimized environmental management and rearing strategies.
