First record of Conidiobolus coronatus (Zygomycetes: Entomophthorales) in experimental breeding of two pest species of corn: Delphacodes kuscheli and D. haywardi Muir (Hemiptera: Delphacidae) in Argentine. Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.3-4, pp.169-174. ISSN 1851-2372.

The natural occurrence of the entomopathogenic fungus Conidiobolus coronatus (Costantin) Batko (Zygomycetes: Entomophthorales) in adults of Delphacodes kuscheli Fennah and D. haywardi Muir (Hemiptera: Delphacidae), reared on Hordeum vulgare L. under greenhouse conditions, was investigated. Dead insects, suspected of fungal infection, were collected, surface sterilized, and examined in the laboratory. Conidiobolus coronatus was isolated in pure cultures, described morphologically, and deposited in mycological collections. This paper presents the first record of C. coronatus against harmful insects in Argentina.
