Establishment of a cell line from Chrysodeixis chalcites permissive for Chrysodeixis chalcites and Trichoplusia ni nucleopolyhedrovirus.
A new cell line was established from the embryos of the insect Chrysodeixis chalcites (Lepidoptera, Noctuidae, Plusiinae). The cell line contains several morphologically different cell types and was distinguished from three other lepidopteran cell lines propagated in the laboratory by DNA amplification fingerprinting. The cultured cells, which we officially named WU-CcE-1 cells, were permissive for infection by C. chalcites nucleopolyhedrovirus (ChchNPV) and large numbers of occlusion bodies were produced that retained their infectivity for C. chalcites larvae. The CcE-1 cells were also permissive for Trichoplusia ni single nucleopolyhedrovirus (TnSNPV). ChchNPV could be passaged in these cells for at least four passages indicating that budded virus production was supported. Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and Helicoverpa armigera (Hear) NPV both induced apoptosis in these cells. The results obtained indicate that the CcE-1 cell line will be a useful tool in the study of both ChchNPV and TnSNPV.
