Sericulture is considered agriculture and creates employment mainly in rural areas; hence, it does not need an explanation for its role and importance. Silk is the cultural tradition of India and the sericulture industry, wherein the distribution of currency is from rich to poor. It is providing nonstop profits to farmers as it is employment and income creating income industry, it is so entitled as the “Kalpvriksha” or “Kamdhenu” of the poor farmers (B.K et.al.,1994). In this study, two different eco-regions, the first in Parsendi and the second in Lucknow, observed food habits, length, width, and different larval stages of mulberry larvae and analysed mulberry silk cocoon length, cocoon weight, and cocoon width at different sites. We observed the life cycle of mulberry silk worm larvae at both sites. We find the larval length (Tech) and cocoon weight developing better in Parsendi sites than in Lucknow region. The life cycle of the mulberry silk moth in the Parsendi region takes 23 days, and that of the Lucknow region takes 25 days. We observe that in the Parsendi region, mulberry silk worm rearing is more stable than in the Lucknow region.
