Abstract—The entomopathogenic fungus Beauveria bassiana, an infections in silkworm [10]. In some subtropical and
important biological control agent of lepidopteron, is also the key temperature agricultural systems, this entomopathogen causes
pathogen to cause epizootic among the silkworm, Bombyx mori, a a high level of mortality and yield great losses in silk
kind of insect very economically important as producer of silk in production.
China. At present, very little is known about the isolates that are
associated with the endemic or epizootic phases of this disease Otherwise, silkworm, infected by B. bassiana conidial, is
agent. Random amplified polymorphic DNA (RAPD) band the source of the traditional Chinese medicine "Bombyx
patterns was used to genotypically characterizing the twenty-one batryticatus". In traditional Japanese, Korean, and Chinese
isolates of B. bassiana from the main sericultural areas of China, medicine, it is employed as analgesic and anticonvulsant for
with the host the silkworm, Bombyx mori. Unweighted pair
treating headaches, toothaches, tonsillitis [11], and also used
group mean
