Effect of brown sugars on the productivity of mulberry silkworm Bombyx mori L. (Lepidoptera; Bombycidae) [electronic resource].

Includes reference.

The effect of supplementing mulberry leaves with two nutrient materials; namely, dark brown sugar and light brown sugar at different concentrations on the silkworm bombyx mori L. were investigated for achieving an increase in its productivity. the obtained results indicated that mulberry leaves treated with dark brown sugar at concentration of 3% and the light one at 5% caused significant increase of the mean weights of mature larvae, silk glands and pupae. in addition, both the abovementioned treatments were the most efficient, improving silk and egg production. the estimated values of total haemolymph proteins (THP) of tested larvae confirmed the positive effects of these treatments, whereas the significant highest level of THP coincided almost exactly with the higher productivity of either silk or eggs.
