Abstract

Oral application of dimethyl sulfoxide in different concentration (1, 3 and 5 percent) to silkworm, Bomyx 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 take place significantly, except haemolymph trehalose where it was found to be significant, as compared with that of carrier control.

4령과 5령 누에에 1%, 3%, 5%의 dimethyl sulfoxide를 침식시키면 누에의 실용형질인 잠체중, 견사선 무게, 암·수 견중 및 견충중과 산란량이 현저히 증가했다. 그러나 경과일수, 족중생존율과 부화율은 대조와 큰 차이를 보이지 않았다. 한편 dimethyl sulfoxide 1.3%구에서는 누에의 혈액내 단백질과 트리할로스량을 제외하고는 차이가 없었다.
