  • The activity of two isolates of Spotoptera exigua nucleopolyhedrovirus , SeMNPV-M and SeMNPV-Z, was compared by bioassays. The LD50 values of SeMNPV-M and SeMNPV-Z in 3rd instar host larvae were 195. 8 PIBs/ gram diet and 242. 4 PIBs/gram diet, respectively. The LT50 values infected with 6000PIBs/gram diet were 3. 50 and 3. 68 days, respectively. The viral suspension formulation pesticide with SeMNPV-Z was produced and in field trials, the SeMNPV pesticide proved to be an effective control agent.

    Abstract: The activity of two isolates of Spotoptera exigua nucleopolyhedrovirus , SeMNPV-M and SeMNPV-Z, was compared by bioassays. The LD50 values of SeMNPV-M and SeMNPV-Z in 3rd instar host larvae were 195. 8 PIBs/ gram diet and 242. 4 PIBs/gram diet, respectively. The LT50 values infected with 6000PIBs/gram diet were 3. 50 and 3. 68 days, respectively. The viral suspension formulation pesticide with SeMNPV-Z was produced and in field trials, the SeMNPV pesticide proved to be an effective control agent.
