Abstract
The silkworm industry plays a crucial role in requiring employment
opportunities, particularly in regions like Tamil Nadu, Assam, Karnataka, West
Bengal, Jharkhand, and Andhra Pradesh. This industry heavily relies on mulberry
plants Morus alba L. as the primary food source for silkworms Bombyx
mori. This study was conducted at Mukkudal (80.756102 N, & 77.526425E).
A sum five trays of B. mori samples were collected for the experiment.
The growth and development of silkworm larvae fed two different mulberry leaf
variants, G4 and MR2, The MR2 mulberry Verity elicits a below-average growth
rate. However, in the later 5th instar, silkworms fed on MR2 exhibit
significantly higher growth performance. Larval duration was also notably
decreased by using MR2 leaves. The MR2 shortened the 5th Instar
cycle by 24 hours to just 168 hours (7 days), compared to 192 hours (8 days)
with G4. Overall, the MR2 mulberry variety clearly stimulates superior
improvements in both cocoon weight and faster mature development in advanced
instar silkworms. Further research into optimal rearing conditions with the MR2
host plant is recommended to support higher efficiency and yield in silk
production.
