Beauveria bassiana (Bals.-Criv.) Vuill.

Beauveria bassiana is a fungus that grows naturally in soils throughout the world and causes disease in various insects by acting as a parasite; it thus belongs to the entomopathogenic fungi. It is being used as a biological insecticide to control a number of pests such as termites, whitefly, different beetles and its use in the control of the malaria-transmitting mosquitos is under investigation. The species is named after the Italian entomologist Agostino Bassi who discovered it in 1835 as the cause of the muscardine disease of silkworms. Beauveria bassiana (formerly also known as Tritirachium shiotae) is the anamorph (the asexually reproducing form) of the fungus species Cordyceps bassiana. The teleomorph (the sexually reproducing form) was discovered in 2001. Image File history File links Beauveria bassiana on a sugar beet root maggot. ...

The disease caused by the fungus is called white muscardine disease. When spores of the fungus come into contact with the body of an insect host, they germinate, enter the body, and grow inside, eventually killing the insect. Afterwards a white mold grows on the cadaver and produces new spores. Most insects living near the soil have evolved natural defenses against the fungus, but many other insects are susceptible.

The fungus rarely infects humans or other animals, so it is generally considered safe as an insecticide. As an insecticide, it is sprayed on affected crops or applied to mosquito nets as a malaria control agent. A mosquito net offers protection against mosquitos, flies, and other insects, and thus against diseases such as malaria. ...
