Although these two cell lines had been derived from the same insect species,they varied largely in their response to challenge with the Pcr NPV.The percentage of infected cells with polyhedra in Pcr-S1 cell line was 52.9% and each infected cell produced 21 polyhedra on average.This demonstrated that Pcr-S1 cell line could be an excellent in vitro system for studing Pcr NPV replication and for biotechnical application as well.
