HaSNPV-HHR3 budded virus and occlusion body virus were constructed in three steps： preparation of pFastBacHaPhpP10-HHR3 donor plasmid, transposition of HHR3 into the HaBacHZ8 bacmid, and transfection of HzAM1 cells to get HaSNPV-HHR3 virus.HHR3 was proved to be expressed in the HaSNPV-HHR3 virus infected HzAM1 cells by immunoblotting. Results of bioassay indicated that the body weight of the HaSNPV-HHR3 infected larvae was lower than the larvae infected with wild virus and uninfected normal larvae, which suggests that HaSNPV-HHR3 delayed larval growth.展开更多
