“…Such conditions are reported in the B. mori creation room, which increases the infection and favours the multiplication and spread of the pathogen. Some previous studies conducted in sericulture regions of Brazil and other countries have shown fungal incidence in B. mori larvae (ALVES, 1998;KUMARI et al, 2011). However, data that correlate symptoms and histopathology of infection are scarce.…”

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.

“…Em seguida, estudos in vivo também foram conduzidos com lagartas de B. mori, pela infecção prévia das lagartas com B. bassiana e posterior aplicação do extrato de algas, conferindo de 75 a 85% de redução da mortalidade pelo patógeno (Kumari et al, 2011).…”

Entomopathogens are the most important problem from sericulture all over the world, and cause heavy loss to silkworm crops. Calcinosis is a common disease of silkworm, caused by the pathogenic fungus Beauveria bassiana (Bals.) Vuill. (Ascomycota: Cordycipitaceae). Fungal diseases of silkworm are easily spread by spores which are carried through the air. Also, temperature and humidity inside the silkworm rearing rooms are favorable to disease development. Practice hygiene measures during silkworm rearing such as disinfection of rearing houses and appliances are recommended. However, contamination is frequent. This paper presents related research on promising antimicrobiotic products for their use in sericulture industry.KEYWORDS: silkworm; Beauveria bassiana; sericulture. RESUMO:Um dos principais problemas enfrentados pelos sericicultores em todo o mundo são entomopatógenos que causam grandes perdas na produção. Destaca-se a doença calcinose branca, causada pelo fungo Beauveria bassiana (Bals.) Vuill. (Ascomycota: Cordycipitaceae). Doenças fúngicas são facilmente disseminadas, já que os conídios são transportados pelo ar. Além disso, as condições de temperatura e umidade nos barracões são favoráveis ao surgimento e à manutenção do fungo, aumentando sua incidência. Práticas de higiene como a desinfecção do barracão e de utensílios são recomendadas, no entanto a contaminação das lagartas ainda é frequente. Dessa forma, esse artigo reuniu trabalhos voltados para a pesquisa de produtos antimicrobianos alternativos para o uso em sericicultura.
