| Abstract: | Baculoviruses from Autographa californica (AcNPV-E2) and Spodoptera frugiperda (SfNPV-2) were titered in five insect cell lines: IAL-PID2, IAL-SFD1, IPLB-SF-21AE, TN-368, and IAL-TND1. AcNPV-E2 replicated in all the cell lines while SfNPV-2 did not replicate in the lines TN-368 and IAL-TND1. Further in vivo studies of SfNPV-2 showed the virus was not infectious when fed to Trichoplusia ni larvae per os or when injected into the hemocoel. These data suggest that the barrier to SfNPV-2 infectivity in T. ni is at the cellular level, as opposed to the midgut. |
