Barta, Marek & Ludovit Cagan. Pandora uroleuconii sp. nov. (Zygomycetes: Entomopthoraceae), a new pathogen of aphids. Mycotaxon 88: 79 - 86. 2003.

ABSTRACT: Pandora uroleuconii sp. nov. is described and illustrated. It possesses branched conidiophores, ellipsoid to ovoid monokaryotic and bitunicate primary conidia, pseudocystidia, and large nuclei staining distinctly with aceto-orcein. Rhizoids are absent. The pathogen differs from other species of the genus by absence of rhizoids, different size of primary conidia, growth on standard media and probably high host specialization. P. uroleuconii attacked aphid species Uroleucon aeneum during May and June in many localities in Slovakia. The species did not grow on standard media and did not exhibit infectivity to five common aphid species, Acyrthosiphon pisum, Diuraphis noxia, Metopolophium dirhodum, Myzus persicae and Rhopalosiphum padi. The new fungal species is compared and contrasted with similar species of the genus.

KEYWORDS: Entomophthorales, aphidophagous fungi, Uroleucon aeneum, Slovakia
