摘要: A clone of the wild type (wt) Anticarsia gemmatalis multiple nuclear polyhedrosis virus AgMNPV, derived from a geographical isolate (Hondrina, Brazil) and designated AgMNPV-CL4-3A1, was used to determine host range this in six established lepidopteran cell lines: (BCIRL-AG-AM1), Helicoverpa zea (BCIRL-HZ-AM1), Heliothis virescens (BCIRL-HV-AM1), armigera (BCIRL-HA-AM1), Trichoplusia ni (TN-CL1), Bombyx mori (BMN), coleopteran line Anthonomus grandis (BRL-AG-1). In addition, vivo also assayed larvae zea, virescens, ni, homologous species by probit analysis. On basis temporal studies TCID50 values, BCIRL-HV-AM1 cells gave highest extracellular (ECV) titer (9.7×106 TCID50/ml) followed BCIRL-HA-AM1 (8.3×105 BCIRL-AG-AM1 (3.2×105 TCID50/ml). low ECV 1.37×103 TCID50/ml detected TN-CL1 96 h postinoculation, while BRL-AG-1, BMN, BCIRL-HZ-AM1 were nonpermissive AgMNPV-CL4-3A1 on results. AgMNPV had similar restriction profiles that different AcMNPV. The LC50 values 96.9, 564.6, 733.3, 1.1×104 occlusion bodies/cm2 diet for A. gemmatalis, T. respectively.
