Natural occurrence of entomopathogenic fungi (Zygomycetes : Entomophthorales) of aphid (Hemiptera : Aphididae) pests of horticultural crops in Argentina
BioControl 52 (5), 641-655
Abstract: A three-year survey of entomophthoralean pathogenic fungi of aphids from horticultural crops in La Plata, Argentina, was conducted. Nine species of aphids, including Aphis fabae Scopoli, Aphis gossypii Glover, Brevicoryne brassicae (L.), Lipaphis erysimi (Kaltenbach), Macrosiphum euphorbiae (Thomas), Myzus sp., Myzus persicae (Sulzer), Nasonovia ribisnigri (Mosley) and Capitophorus elaeagni (del Guercio) were recorded as hosts of entomopathogenic fungi. Six species of Entomophthorales that infected and killed aphids were found in vegetable crops. The fungal species identified were Conidiobolus obscurus (Hall and Dunn) Remaudière and Keller, Entomophthora planchoniana Cornu, Neozygites fresenii (Nowakowski) Remaudière and Keller, Pandora neoaphidis (Remaudière and Hennebert) Humber, Zoophthora radicans (Brefeld) Batko and Zoophthora sp. Pandora neoaphidis was the most predominant pathogen of aphids and was found throughout the summer (December-March) 2004. The recovery of C. obscurus, N. fresenii and P. neoaphidis represent first records of these fungi for South America.
