RESUMO: O isolado E9 de Metarhizium anisopliae foi usado em larvas híbridas de Bombyx mori para avaliar seu efeito biológico. A sintomatologia revelou sinais típicos de infecção por fungos. Na histopatologia foi verificado um aumento no número de hemócitos, sendo que, no 6 dpi, todo o corpo do inseto se apresentou colonizado pelo fungo. O isolado E9 é patogênico para lagartas de B. mori, causando sua morte pela colonização dos tecidos de origem epidérmica e mesodérmica.

ABSTRACT: The isolate E9 of Metarhizium anisopliae was used in commercial hybrids of Bombyx mori larvae to evaluate its biological effect. Symptomatological analyses showed typical signs of fungal infection. Histopathology revealed the presence of large numbers of hemocytes in the hemocoel, and on the sixth dpi the bodies of the insects appeared to be colonised by the fungus. The isolate E9 is pathogenic to larvae B. mori and; therefore, death of the insects was caused by the colonization of fungus in the epidermal and mesodermal tissues.
