Step-by-step solution
Bacillus thuringiensis is a bacterium used as a biocontrol agent against lepidopteran insects, such as the cabbage worm. Beauveria bassiana is a fungus that acts as a parasite on various arthropod species, causing white muscardine disease, and is used to control pests like mealy bugs. Nosema locustae is a microsporidian parasite specifically used as a biological control agent against grasshoppers and locusts. Nucleopolyhedrovirus (NPV) is a type of baculovirus that is highly species-specific and is widely used for
