Extract from Wikipedia article: Beauveria bassiana is a fungus that grows naturally in soils throughout the world and acts as a parasite on various arthropod species, causing white muscardine disease; it thus belongs to the entomopathogenic fungi. It is being used as a biological insecticide to control a number of pests such as termites, thrips, whiteflies, aphids and different beetles. Its use in the control of bedbugs and malaria-transmitting mosquitos is under investigation.

Beauveria bassiana is an entomopathogenic fungus in the phylum Ascomycota that infects and kills insects. In East and Central Texas, it has been isolated from various insect hosts, including whiteflies, aphids, and beetles. The fungus is commonly found in soil and on vegetation, with optimal growth temperatures between 20-25°C. Studies have shown that B. bassiana is widespread in the region, with high prevalence in areas with suitable humidity and temperature conditions. It has been identified as a potential biological control agent for managing insect pests in agricultural ecosystems in East and Central Texas.
