Relationship between dietary conditions, and chemical properties of chorion of the silkworm, Bombyx mori, was investigated by means of electron probe X-ray microanalysis and differential thermal analysis. Sulfur, calcium, phosphorus and potassium were detected on the surface of the chorion by X-ray microanalysis. Among these, sulfur was the predominant component. It was demonstrated on the basis of spot-analysis, line-analysis, and surface-analysis that sulfur and calcium were distributed uniformly on the surface of the chorion. The amount of sulfur of the chorion was lower in the rearing on a semi-synthetic diet than in the rearing on a mulberry leaves. However, when the larvae were reared on a semi-synthetic diet supplemented with methionine and cystine, sulfur content of the chorion became as high as in the rearing on mulberry leaves. Results of differential thermal analysis of the chorion also supported the above results.
