Abstract

Cocoons, cocoon shells and chrysalis of four races of Bombyx mori L., two from China (C202 and C212) and two from Japan (B104 and M11-2), were analyzed in function of determinant factors as weight (dry mater and moisture) and by hygroscopic capacity after cooking. It was used a complete randomized design, with four treatments and ten replications. Although the cocoon shell has a higher hygroscopic capacity, the percentage of water in the chrysalis is the main factor to determine the weight of cocoon. The percentage of water in the cocoon and its components are inversely related to the absorption after cooking. Of all races evaluated, the chinese ones had lower percentage of water in the cocoon and higher cocoon shell weight than the japanese races.
