Abstract: | Vairimorpha necatrix infected adipose ceiis of the fat body organ of Trichoplusia ni larvae 3–31/2 days after exposure of the larvae to infective spores. During the subsequent 4–6 days, the parasitized adipose cells were hypertrophied in part due to the rapid propagation of V. necatrix schizonts. A calcium-sensitive tubule network developed at the interface of the schizonts and the adipose ceil cytoplasm. The paired nuclei of V. necatrix have pores at the nuclear interface. The pores for each nucleus at this interface are spatially positioned so that they are in conjunction; hence, there is the potential for a channel system between the 2 nuclei. |
