Isaria poprawskii sp. nov. (Hypocreales: Cordycipitaceae), a new entomopathogenic fungus from Texas affecting sweet potato whitefly.
TL;DR: I. poprawskii was shown to be closely related to I. javanica ; however, it formed its own unique clade, thus confirming its status as a new fungal species.
Journal ArticleDOI
Use of cell culture media for cultivation of the mite pathogenic fungi Neozygites tanajoae and Neozygites floridana.
TL;DR: It is demonstrated that differences in nutritional requirements exist between N. tanajoae and the similar species, N. floridana, and the distinction of these two species was initially proposed based on host specificity, genetic and physiological patterns and is supported by the results presented in this study.
Journal ArticleDOI
Entomopathogenic Fungi in Flies Associated with Pastured Cattle in Denmark
TL;DR: A 2-year study of the natural occurrence of entomopathogenic fungi in adult cattle flies and other flies associated with pastures showed that the four species included in the Entomophthora muscae species complex caused high infection levels in several species of flies.
Journal ArticleDOI

TL;DR: Nigelia is described as a new genus closely related to Metarhizium, to the scale insect pathogens Aschersonia, Samuelsia and Moelleriella, and to plant pathogens in Claviceps and Balansia, and other relatives.
Journal ArticleDOI
What's in a name? Aschersonia insperata: a new pleoanamorphic fungus with characteristics of Aschersonia and Hirsutella.
TL;DR: A new anamorphic species from a Philippine tropical forest occurs as reddish-orange to orange, tuberculate stromata on unidentified homopteran larvae, and produces both Aschersonia and Hirsutella-like synanamorphs.
