Abstract
|
|
|
|
Oral application of dimethyl sulfoxide in different concentration (1, 3 and 5 percent) to silkworm, Bombyx mori at the fourth and the fifth instar has significantly increased the commercial characters such as larval and silkgland weights, female and male cocoon weights, their shell weights and egg production. However, larval duration, cocooning and hatching percentages did not showed any significant change, as compared with that of the corresponding parameters of the carrier control. Similarly the glycogen and protein contents of the fat body and trehalose and protein contents of the haemolymph were significantly increased in 1 and 3 percent, whereas the increase of them in 5 percent concentration did not takes place significantly, except haemolymph trehalose where it was found to be significant, as compared with that of carrier control.
