Histopathological and Cytopathological Changes in Pieris rapae Infected by New Nodavirus
Abstract: The major pathological changes of Pieris rapae infected by a new nodavirus (PrNV) and a mixture of PrNV and Pieris rapae Granulosis virus (PiraGV) were studied by electron microscopy and histochemisty. The results showed that PrNV replicated only in the cytoplasm of larval midgut cells. After infection, prominent changes took place in the organelles of permissive cell, such as mitochondrion, endoplasmic recticulum and ribosome. The PrNV assembly was also studied.
