A prevalent disease was observed among the larval populations of the cupreous chafer at Shizuoka and Nara Prefs. and an entomopoxvirus (EPV) was found as the causative agent. The EPV multiplies in the fatbody and bemocyte, and two types of inclusions, spheroid and spindle-like inclusions, were formed in the cytoplasm. The spheroid inclusions, 5×8 μ in size, contains numerous virions and have a crystalline lattice structure of 116 Å in distance. The spindle-like inclusion, mostly octahedral with obtuse edges, has also a crystalline structure 50〜57 Å in distance, but devoid of virus particles. The spherical immature virus particles gradually differentiated and occluded within paracrystalline inclusions, which develop to spheroids. The virus particles are 4400 Å in length and 2500 Å in width with mulberry surface. The core is bound by a core shell which is about 200 Å thick consisting or electronlucent outer and inner layers, and is concave on one side and convex on the other. It contains a rope-like structure about 350 Å in diameter.
