“…The sprinkled plate method is regarded as less efficient for recovery of endoparasitic fungi, and to recover larger amounts of endoparasitic fungi methods involving extraction of nematodes have to be performed [24, 25]. The nematodes from rhizosphere or root‐free soil were extracted, in 3 replicates, with the Baermann funnel method (see below).…”

In a field experiment the rhizosphere effect of barley, pea and white mustard on the nematode‐trapping fungi were investigated throughout a growing season. The densities of nematode‐trapping fungi were slightly increased in the rhizospheres compared to the root‐free soil. Pea rhizosphere had the greatest numbers of species of nematophagous fungi with an average of 2.4 species recovered from 0.1 g material, and in white mustard and barley rhizospheres and root‐free soil less than 1.7 species were recovered from 0.1 g. Arthrobotrys oligospora was the most common species in both soil and rhizosphere. In a pot experiment the rhizosphere effect of pea and barley on nematophagous fungi was investigated in 5 different agricultural soils. Pea rhizosphere increased the densities of nematode‐trapping fungi, and up to 780 propagules of nematode‐trapping fungi g−1 rhizosphere soil were found, which was around 19 times higher than in the root‐free soil. The number of nematodes were 6–290 times higher in the pea rhizosphere than in the root‐free soil. Barley rhizosphere had little effect on the densities of nematode‐trapping fungi, while the number of nematodes increased by 3–13 times. The most commonly detected species were A. oligospora, Stylopage sp. and network‐forming Monacrosporium species, but there were no big differences in the species composition between the rhizosphere and the root‐free soil.

“…K balanoides was reported as an endoparasite of Rhabditis terricola from various soils in Ontario (Barron, 1978), from moss in birchwood in England (Duddington, 1951) and from deciduous and coniferous leaf litter, old dung and coastal vegetation in Ireland (Gray and Duff, 1982;Gray, 1983c). The species occurred in 50 % of soil samples taken from agricultural soils in Westfalen, F.R.G.…”

Nine nematophagous species and two varieties of Verticillium (Verticillium sect. Prostrata), occurring either as parasites of free-living nematodes or as parasites of cysts and eggs, are revised and keyed out. E catenulatum is reduced to a variety of V. chlamydosporium. A similar fungus is distinguished as V. suchlasporium n. sp. (including a var. catenatum). Spicaria coccospora Drechsler is transferred to Verticillium. All species have been studied in pure culture. Ecological data are reviewed for each species.

“…The identified fungi were stored in test tubes of 20 ml KIMAX ® , with sloping CMA and mineral oil Faga-Lab ® at 4 °C for later use in pathogenicity tests (Kerry , 2001). The times of appearance of nematophagous fungi vary considerably, and in order to recover most of the species in a particular sample, the plates must be examined daily for up to ten days to make sure to find potential nematophagous fungi in the soil including slow growth (Barron, 1978).…”

“…Preparations and identifications of nematophagous fungi were studied by direct observation under a compound microscope Nikon Eclipse E200 at different magnifications because some structures are accessible in minor magnification, structures like growing mycelium, conidiophores and conidial were compared, trapping structures was only possible to observe de las especies en una muestra en particular, las placas deben ser examinadas diariamente durante un máximo de diez días para asegurar encontrar los posibles hongos nematófagos del suelo incluyendo los de crecimiento lento (Barron, 1978).…”

ResumenLa producción de diversos cultivos hortícolas en el norte de Sinaloa, está siendo limitada por el ataque del "nematodo nodulador" Meloidogyne spp. La búsqueda de alternativas para el manejo de este fitoparasito surge como respuesta a esta problemática, entre estás el aislamiento e identificación de hongos nematófagos nativos del Valle del Fuerte. El objetivo de la presente investigación fue identificar hongos nematófagos existentes en suelos donde se producen cultivos en condiciones protegidas y susceptibles a Meloidogyne spp. El estudio se realizó de enero 2013 a julio 2014 en cuatro zonas productoras de chile c.v. Lorca Bell Pepper del Valle del Fuerte, donde se recolectaron muestras de suelo, las cuales fueron procesadas mediante el método de espolvoreado en placa (agua-agar). Para purificar y seleccionar hongos nematófagos, los aislamientos se transfirieron a placas con agar harina de maíz, identificándose las estructuras morfológicas para el diagnóstico a nivel género. Se identificaron a los generos: Dactylella, Arthrobotrys y Nematoctonus.Palabras clave: Dactylella, Arthrobotrys, Nematoctonus, hongos nematófagos. AbstractProduction of various horticultural crops in northern Sinaloa, is being limited by the attack of "root-knot nematode" Meloidogyne spp. The search for alternatives to manage this plant parasite rises as response to this problem; among the solutions is isolation and identification of native neumatophagous fungi from Valle del Fuerte. The aim of this research was to identify existing nematophagous fungi in soils where crops are grown under protected conditions and susceptible to Meloidogyne spp. The study was conducted from January 2013 to July 2014 in four producing areas of pepper c.v. Bell Pepper from Valle del Fuerte, where soil samples were collected, which were processed through the sprinkling plate method (wateragar). To purify and select nematophagous fungi, isolates were transferred to plates with agar cornmeal, identifying morphological structures for diagnostic at genus level. Identified genres were: Dactylella, Arthrobotrys and Nematoctonus.
