All the microbes mentioned can be used as pesticides. Single cell organisms, such as bacteria, fungi and protozoa, and viruses, have been mass produced and formulated for use in a manner similar to insecticides. Eg - Bacillus Thuringiensis.
Several fungi have been studied as potential microbial insecticides. Beauveria bassiana can affect a wide variety of arthropods. Virus can also be used as insecticide. Baculoviruses are a family of naturally-occurring viruses known to infect only insects and some related arthropods. Most are so specific in their action that they infect and kill only one or a few species of Lepidoptera larvae (caterpillars), making them good candidates for management of crop pests with minimal off-target effects.
