Aislamiento de Conidiobolus coronatus a partir de una plaga de áfidos del cebollín (Allium schoenoprasum L. ) / Conidiobolus coronatus isolation from a pest aphids of chives (Allium schoenoprasum L. )

Conidiobolus coronatus, entomoftoral patógeno para el hombre y algunosinsectos, se aisló a partir de especímenes muertos del áfido Neotoxopteraformosana sobre hojas de Allium schoenoprasum. La presencia deC. coronatus supone el riesgo de una potencial infección para quienestrabajan en la producción de cebollín. El control fitosanitario de N. formosanapodría, además, contribuir a reducir el riesgo de infección humana conC. coronatus(AU)

Conidiobolus coronatus (Entomophthorales), a pathogen of human and someinsects, was isolated from dead specimens of the aphid Neotoxopteraformosana present on chives leaves. C. coronatus infected aphids could posea threat to growers health. Pest control strategies of N. formosana may alsocontribute to reduce the human infection risk by C. coronatus(AU)

[Some micromycetes isolated from spoiled food and soil in Argentine Antarctica]. / Algunos micromicetes del suelo y de alimentos deteriorados en la Antártida Argentina.

The main objective of this study was to identify some micro fungi isolated from soil of Potter peninsula (Antarctica), which were involved in food spoiling at Jubany base. Different solid culture media were used to isolate 66 fungal strains from spoiled food and soil. Twelve saprophytic, spoiling and/or toxicogenic taxa belonging to the genera Doratomyces, Geomyces, Oidiodendron y Penicillium were identified; eight of them with full descriptions and drawings. This is the first record of Geomyces pannorum var. vinaceus and Oidiodendron griseum recovered from the Argentine Antarctica.
