Mamestra brassicae nucleopolyhedrovirus (MabrNPV) has a wide host range, including 32 species spanning five Lepidoptera families.
Some of its targets are important pests, such as Plutella xylostella, H. armigera, S. exigua, and Xestia c-nigrum. A Mamestra brassicae nucleopolyhedrovirus (MabrNPV), originally isolated from M. brassicae larval cadavers on oilseed rape in 1979, was successfully developed as an insecticide produced in either H. armigera or S. exigua reared on an artificial diet.
