Resumen

An ultrastructural description is given of nuclear polyhedrosis virus (NPV) morphogenesis in vitro, with emphasis on changes occurring during long-term serial passage of infectious material. The morphogenesis and infectivity of early passage virus is similar to that which obtains in vivo. The infectivity of polyhedra prepared from late passage infected cultures is greatly diminished; this is paralleled by both a decrease in the total number of polyhedra produced and a decrease in the number of morphologically normal occluded virus particles. Late passage viral morphogenesis is profoundly changed. New observations concerning the acquisition of membranes by NPV nucleocapsids and polyhedron formation are discussed.
