Abstract
Environmental conditions and rearing technologies play a crucial role in influencing the physiological health and cocoon quality of the silkworm (Bombyx mori). This study provides an in-depth analysis of how key environmental factors—such as temperature, humidity, light, and air quality—affect silkworm metabolism, growth, and cocoon formation. It identifies the ideal environmental parameters for each developmental stage and evaluates how modern rearing systems can be used to improve silk yield and quality. The significance of nutrition, especially the quality of mulberry leaves, in determining cocoon structure and silk filament strength is also emphasized. Through case studies from various sericulture regions, the research illustrates practical applications of these insights. The findings highlight the importance of combining innovative technologies with traditional sericulture methods to achieve sustainable, high-yield, and superior-quality silk production. This paper serves as a useful resource for researchers, sericulture farmers, and policymakers seeking to enhance silkworm productivity and silk quality through optimized environmental and rearing practices.
