| Abstract: | The results of infection tests on the nuclear polyhedrosis virus of Chihuo zao Yang (CzNPV) were reported. Early third-instar larvae or fourth-instar larvae of six kinds larvae( Chihuo zao, Semiothisa cineraria, Leucoma salicis, Lymantria dispar, Euproctis flava, Arge captiva) were fed on their host leaves immersed with polyhedral inclusion bodies (PIB) suspension of CzNPV 2 5×107 PIB/ml. Only the larvae of Chihuo zao Yang were infected by CzNPV and the adjusted mortality of larvae were 96 5%. The other five kinds larvae were not infected by CzNPV. The results of infection tests indicated that CzNPV were high special concentrated for its original host Chihuo zao Yang and effective control for larvae of Chihuo zao Yang. |
