Sericulture involves cultivating mulberry plants and rearing silkworms to produce silk cocoons and silk yarn. Adoption of integrated management technologies is essential to address challenges in sericulture. A study on the adoption of 30 important bivoltine sericulture technologies was conducted in five districts of the Tenkasi sericulture cluster in southern Tamil Nadu. In Tenkasi district, 56.67% of technologies showed high adoption, while 23.3% and 20.0% fell under medium and low adoption categories, respectively. Tuticorin recorded the highest level of adoption, with 66.67% of technologies under high adoption and only 10.0% under low adoption. Tirunelveli showed 40.0% high adoption, 33.33% medium adoption, and 26.67% low adoption. In Virudhunagar, 30.0% of technologies had high adoption, 40.0% medium adoption, and 30.0% low adoption. Kanyakumari reported 33.33% high adoption, 56.67% medium adoption, and 10.0% low adoption. Adoption gaps in mulberry cultivation and sericulture practices varied considerably across districts. Mean adoption gaps ranged from 15.0% in Tuticorin to 30.71% in Tirunelveli. Overall, farmers moderately adopted technologies related to rearing silk worms and cocoon harvesting, while pre-rearing and disinfection practices received greater attention. The findings highlight to initiate appropriate measures to raise awareness and bridge the adoption gap and the need to motivate farmers to adopt these technologies in order to increase the cocoon production and profitability.
