Abstract

Beauveria bassiana can be used as a biological pesticide to control a number of pests such as locust, grasshoppers, whiteflies, termites and other insects. It is spread on affected crops as an emulsified suspension. As a fungal species, Beauveria bassiana parasitizes a wide range of arthropod hosts. However different strains vary in their host ranges, some having narrow ranges, like the strain Bba 5653 which is very harmful to the larva of locust. White Muscardinae disease causing cosmopolitan fungus, Beauveria bassiana, naturally grows in soil and act as a parasite on numerous species of arthropods and thus it belong to entomopathogenic fungi. This fungus is cultured in laboratories under in-vitro conditions and spores are made from this fungus, which are sprayed in crop fields of rice, maize etc. When the microscopic fungal spores acquire contact with the body of an arthropod host, it penetrates the cuticle after germinating, grows inside it, and kills the insects within a few days. This is followed by emergence of a white mold from the cadaver which produces new spores. This paper discusses the role of Beauveria bassiana as a potent biopesticide against locusts.
