Silkworm (<I>Bombyx mori</I>) blood has a characteristic flow behavior, and it depends on the metaphoresis of silkworm. Silkworm has also interesting biological function, as for example, it makes a cocoon and changes itself to a puppa.<BR>In this paper, effect of the biological function on dispersion state of silkworm blood was studied by cone-plate type viscometer (LS-40), electron microscope, and GC Mass Spectrography. Silkworm blood used throughout this experiment was obtained from different sources of silkworm and different stages in the age of the silkworm. Non-Newtonian flow behavior and viscosity value of various stages and sources at low shear range, and dependence of biological function on viscosity of silkworm blood were observed. The silkworm blood viscosity changes with the change of source and stage of silkworm, because it depends on the facility of aggregate structure formation. It was found that the viscosity of the regular type of silkworm blood increases with age, however, its viscosity during a certain period exhibited the lowest value. These flow properties of silkworm blood depend on the complicated dispersed state of blood cell particles. From the electron microscopic observation, it was shown that the blood cell contained two main particles, one spherical, and another, the fibrous rod form and, these forms become entangled, hence the complicated aggregate structure is formed. This formation change in aggregate structure was observed with the various stages of silkworm age, and various sources of silkworm.
