Influence of turmeric (Curcuma longa) tea on the growth and cocoon characters of a Philippine silkworm (Bombyx mori) hybrid
Abstract
Turmeric (Curcuma longa) tea in various concentrations was tested on a promising Philippine silkworm (Bombyx mori) hybrid, DMMMSU 346, and was reared during dry, wet, and cool seasons to determine its influence on the growth and cocoon characters. The effects of the different concentrations of turmeric tea and rearing seasons were measured in terms of larval growth parameters; and cocoon and post-cocoon characteristics. Disease incidences at the larval stage as well as silk reliability were also evaluated. The study was carried out using a two-factor experiment in a Completely Randomized Design (CRD). Results showed that both turmeric tea concentration and rearing season significantly influenced the length and weight of silkworms, cocoon shell weight, filament length, and filament size. Disease incidences during the larval stage as well as resulting silk reliability during the post-cocoon assessment were significantly affected by the rearing season. Further, turmeric tea concentration significantly affected cocoon shell percentage. Adding turmeric tea to the mulberry diet of silkworms at a certain concentration and rearing season can improve the larval growth, cocoon, and post-cocoon traits.
