Storage duration of bivoltine Silkworm (Bombyx mori L.) hybrid cocoons: its effect on reeling performance and cocoon characteristics
Abstract
This investigation explored the reeling performance of bivoltine hybrid cocoons as affected by different storage duration and it was conducted at the Sericulture Research and Development Institute, Don Mariano Marcos Memorial State University, Sapilang, Bacnotan, La Union, Philippines from January 2019 to December 2020. The different storage durations which served as the treatments were as follows: TO – non storage, T1 – 1 mo., T2 – 3 mos., T3 – 5 mos., T4 – 6 months. Results revealed no significant difference among treatments in terms of cocoon characters. The reeling percentage showed no significant difference among treatments whereas in terms of raw silk percentage, T0 recorded the highest with 27.90%. As to renditta, T2 recorded the highest (13kg) but comparable to all other treatments except for T0. Reeling waste percentage recorded highest from T1 (53.30) but comparable with T0 (50.50%). The performance of silkworm hybrid cocoons on raw silk quality showed that all treatments were comparable in terms of unevenness. The profitability analysis showed that unstored cocoons (T0) produced the highest raw silk yield, gross income and ROI.
