Major occlusion‐derived virion forms. Three major OB phenotypes are illustrated in the background. The nucleopolyhedrovirus (NPV) OBs are larger than the Granulovirus (GV) OBs due to the fact that they contain multiple numbers of ODV virions. The OBs of GVs are capsule shaped and contain only single virions. The OBs of NPVs are multisided crystals or polyhedra. Some species of NPVs produce cuboidal OBs. The NPVs are further divided into the multiple nucleopolyhedroviruses (MNPVs) and single nucleopolyhedroviruses (SNPVs). The multiple (M) and single (S) designations are in reference to the number of nucleocapsids that are found in each virion. The ODVs of MNPVs, SNPVs, and GVs are depicted in the foreground. The ODVs are illustrated in dissected views and the GV ODV is illustrated as partially encapsulated.
