Entomophthoralean fungi had been poorly studied inArgentina until about 2000 there had been very few reports of insects infectedwith Entomopthorales. Agricultural insect pests had been mostly surveyed fromhorticultural, soybean, rice and cereal crops and several species wereidentified infecting insect hosts. Some few of the species were isolated inaxenic pure cultures and deposited at Culture Collections. Up to present timenine species of Entomopthoralean fungi had been recorded in agricultural pestsand also from sanitary insect vectors as houseflies.Atotal of nine fungal species and several strains and an abroad list of insecthosts had been surveyed from pampasic and Litoral region of Argentina includingBuenos Aires , Santa Fé, Entre Ríos ,and Corrientes. Provinces. The orders of insect hosts that were recordedwere: Lepidoptera, Hemiptera, Thysanoptera, and Diptera. The morphologicalfeatures were studied as also type and nuclei number, diameters of conidia andnuclei, rizoids, cystidia presence and resistance spores. For some of the speciesalso molecular characterization was done to confirm ID. The list of fungalspecies recorded Entomopohthora planchoniana Cornu, E.ferdinandii, S. Keller Pandora neoaphidis (Remaudiere &Henebert) Humber, Zoophthora radicans (Berf.) A. Batko, Zoophthora sp, P. neoaphidis, Pandora sp. Pandora dipterigena (Thaxt.) Humber  Conidiobolusobscurus  (I.M: Hall & P.H. Dunn )remaud. & S. Keller ,C. coronatus (Costantin) Batko and Batkoa sp. Neozygites. fresenii (Nowak.) Remaud. & S.Keller,and Neozygites sp. (weredeposited  at Fungal Culture Collection //andat Fungarium, of   CEPAVE, La Plata andin ARSEF CultureCollection, Ithaca, NY., U. S. A.). Spore resitance andepizootiological studies are also reported
