Abstract
The immunized rabbit serum against the polyhedral bodies or the supernatant fluid of the infected larval blood agglutinated the polyhedral bodies and the agglutinins in each serum was absorbed by the homologous and another antigens.
The immunized rabbit serum against the supernatant fluid of the healthy larval blood did not agglutinate the polyhedral bodies. And also the healthy larval blood did not absorb the agglutinin in the other two serums as mentioned above.
When the pupae were immunized with the vaccine made from the infected larval blood, no increase of agglutination titer of the polyhedral bodies could be recognized.
