MbNPV (MAMESTRA BRASSICAE NPV) has a relatively broad spectrum and can infect more than 30 kinds of Lepidoptera insects. MbNPV can be used to develop broad-spectrum viral insecticides.
MbNPV can control pests such as Spodoptera frugiperda, diamondback moth, cotton bollworm, corn borer, rice leaf roller, tea geometrid, tobacco budworm and cutworm. When 2 billion PIB/mL MbNPV SC 750mL/hm2 was applied, the control effect on rice leaf roller 7 days after application reached 90.08%.
And it will not affect the populations of natural enemies such as spiders, staphylinidae latreille, and Cyrtorhinus lividipennis.
