The morphology of a nuclear polyhedrosis virus of Ectropis crepuscularia Schiff., the histopathology of the disease, and deoxyribonucleic acid (DNA) synthesis during the disease process were studied. The polyhedral inclusions measure 1.4 µ in diameter with a range of 0.8–2.1 µ. The virus particles are rods measuring 319 mµ by 79 mµ with a range of 280–360 mµ by 70–110 mµ. DNA labelling and nuclear swelling follow the course of previously described polyhedrosis virus diseases.
