In vitro interaction of Brazilian strains of the Nematode-trapping fungi Arthrobotrys spp. on Panagrellus sp. and Cooperia punctata

Evaluation of the pathogenicity of selected nematophagous fungi.

“…The pathogenicity of nematophagous fungi under in vitro conditions was investigated on a limited number of nematodes species. Using this approach, phytopathogenic (Timper and Brodie 1993, Belder and Jansen 1994, Galper et al 1995, Jacobs 1997, Kumar and Singh 2006, free living (Galper et al 1995;Gomes et al 1999Gomes et al , 2001) and gastrointestinal parasitic (Gomes et al 1999(Gomes et al , 2001) nematodes were investigated. The pathogenicity of nematophagous fungi on Meloidogyne hapla and Globodera rostochiensis under in vitro conditions had been only investigated by Belder and Jansen (1994).…”

“…Only a few nematophagous fungal species have been studied for pathogenicity in vitro. A. oligospora is the most frequently investigated taxon (Timper and Brodie 1993, Belder and Jansen 1994, Galper et al 1995, Gomes et al 2001. P. chlamydosporia is frequently studied as well, but as a pathogen of nematode eggs only (Braga et al 2008, Singh andMathur 2010).…”

Characterization of the nematocidal toxocyst in Pleurotus subgen. Coremiopleurotus

“…It is a blastoconidium-like ovoid knob surrounded by a liquid droplet containing a toxin that attacks nematodes. The use of nematode capture for nutrient supplementation has been previously reported for several species of fungi (Drechsler 1937;Pramer 1964;Barron 1977;Thorn and Barron 1984;Saikawa 1985;Saikawa and Wada 1986;Barron and Thorn 1987;Nakagiri and Ito 1996;Gomes et al 2001;Nordbring-Hertz et al 2002;Barron 2003). Among them, the anamorphic fungi Arthrobotrys spp.…”

“…and Nematoctonus spp. are probably the most well known predators of nematodes (Barron 1977(Barron , 2003Thorn and Barron 1984;Gomes et al 2001). Nematophagous fungi form trapping structures, such as adhesive nets, rings, or adhesive knobs, at intervals along the length of the hyphae under nitrogen-defi cient conditions.…”

The influence of fungicides on Arthrobotrys oligospora in simulated putting green soil

“…to capture the free living nematode Panagrellus spp. and the infective juveniles of Cooperia punctata Travassos, a gastrointestinal parasite of cattle, indicated that A. oligospora was effective at reducing populations of nematodes (Gomes et al, 2000). Since Arthrobotrys spp.…”
