Abstract:

The effect of temperature plays a crucial role in the silkworm, Bombyx mori L., growth as well as cocoon quality and quantity. In this study, the effect of temperature during chawki rearing on later stages and its cocoon production was evaluated without maintaining any recommended practices of temperature and relative humidity during chawki rearing. The perusal of the data reveals that, the larval duration was observed as 28 days and 3 hours. It was observed that the second moult was the longest about 53 hours. Single cocoon weight was observed as 2.22 g, single shell weight was 0.50 g and shell ratio percentage was 22 % and yield obtained was 18.75 Kg per 10, 000 larvae. This finding will help the sericulturists to rear silkworm even at room temperature during chawki stage without any standard procedures without much loss in the cocoon production.


Keywords: Larval duration, cocoon yield, shell ratio and Bombyx mori L.
