First record of Ophiocordyceps dipterigena no Brasil

This note is the first report on the infection of adult stage of Melanagromyza sojae Zehntner, 1900 (Diptera: Agromyzidae) by the entomopathogenic fungus Ophiocordyceps dipterigena (Hypocreales: Ophiocordycipitaceae) (Berk. & Broome) G. H. Sung, J.M. Sung, Hywel-Jones & Spatafora, in subtrop...

Zusammenfassung:This note is the first report on the infection of adult stage of Melanagromyza sojae Zehntner, 1900 (Diptera: Agromyzidae) by the entomopathogenic fungus Ophiocordyceps dipterigena (Hypocreales: Ophiocordycipitaceae) (Berk. & Broome) G. H. Sung, J.M. Sung, Hywel-Jones & Spatafora, in subtropical Brazil. Entomopathogenic fungi, which attack dipteran insects, are of great scientific and economic importance mainly due to their potential as biological control agents of insect pests. Our findings bring new perspectives on the geographical distribution and host range of Ophiocordyceps dipterigena. We emphasize the need of further studies and research on new biological control agents of agricultural pests such as the soybean stem miner fly. Key words: biological control, entomopathogenic fungi, natural infection, stem miner fly, soybean pests. Esta nota e o primeiro registro da infeccao no estagio adulto de Melanagromyza sojae Zehntner, 1900 (Diptera: Agromyzidae) pelo fungo entomopatogenico Ophiocordyceps dipterigena (Hypocreales: Ophiocordycipitaceae) (Berk & Broome) G. H. Sung, J.M. Sung, Hywel-Jones & Spatafora, no Brasil subtropical. Fungos entomopatogenicos, que atacam dipteros, sao de importancia cientifica e economica principalmente devido ao potencial como agentes de controle biologico de pragas de insetos. Este trabalho traz novas perspectivas sobre a distribuicao geografica e variacao de hospedeiro de Ophiocordyceps dipterigena. Destacamos a necessidade de ampliar o conhecimento sobre novos agentes de controle biologico de pragas agricolas como a mosca minadora do caule da soja. Palavras-chave: controle biologico, fungos entomopatogenicos, infeccao natural, mosca minadora do caule, pragas da soja.
