“…Devido a sua forma de ação, o uso do fungo D. flagrans tem atraído muita atenção e tem sido foco de inúmeras pesquisas na última década (NANSEN et al, 1995;FERNÁNDEZ et al, 1999;SARKUNAS et al, 2000;FAEDO et al, 2002;DIMANDER et al, 2003a;DIMANDER et al 2003b;EYSKER et al, 2005).…”

“…The nematophagous fungus, Duddingtonia flagrans, has been researched in several countries (Faedo et al 2002) and, in addition to being commercialized in Europe in barley grain formulation, has been studied in Brazil in sodium alginate formulation . D. flagrans is well known for producing large quantities of resistance structures, called chlamydospores (Grønvold et al 1996;Larsen 2000).…”

“…According to Braga and Araújo (2014), cultural barriers must be broken down since the impact on the environment is minimal, which becomes even more important to study the interaction mechanism of these organisms with their targets. Faedo et al (2002) also reported that it was unlikely that D. flagrans had a negative effect on nematodes that are beneficial to the soil. They observed no fungal predation on the nematode population, suggesting that the fungus exhibited minimal growth around in the fecal environment.…”

“…They observed no fungal predation on the nematode population, suggesting that the fungus exhibited minimal growth around in the fecal environment. According to Faedo et al (2002), evaluation of predatory activity in the soil would be a useful indicator; unfortunately, there are no proper techniques yet available. Additionally this trial shows, that well observed lambs can stay quite healthy and perform enough without anthelmintic treatment even if the graze on contaminated pastures and develop high average EPGs.…”

Effect of spraying Arthrobotrys conoides conidia on pastures to control nematode infection in sheep

et al. 2015

The effect of spraying pastures with conidia of the fungus Arthrobotrys conoides (GenBank ID: JN191309) for the biological control of gastrointestinal nematode infection-pressure in lambs was assessed. A 12,000-m 2 area was divided into six 2,000-m 2 fenced areas. Two groups were formed: the treatment group comprised three fenced areas, where conidia were sprayed on the pasture weekly at 7.5 x 10 4 conidia m -2 ; and the control group, also comprising three fenced areas, where conidia were not sprayed. The pastures included lopsided oat (Avena strigosa Schreb) and Italian ryegrass (Lolium multiflorum Lam.). Five naturally infected lambs, were placed between July and September in each fenced area. The effectiveness of biological control was assessed between May and September 2009 by counting the number of third-stage larvae (L3) in each pasture. Additionally, the egg output of the sentinel animals was monitored by counting the number of gastrointestinal nematode eggs per gram of faeces (EPG) and the average weight gain was measured. The negative impact on soil was assessed by counting the number of free-living nematodes and phytonematodes. The number of gastrointestinal nematode larvae in the treated pastures decreased. This was significant at two examination days (end August and end of September). At the end of the study, conidia treatment reduced gastrointestinal nematodes on pasture by 52.4% compared to the control group; this difference was statistically significant. Regarding the whole examination period the average reductions in EPG in treatment group was 49.1% compared to the control group. The most common genera of gastrointestinal nematodes were Haemonchus and Trichostrongylus. Animal weight gain and soil nematode counts did not differ significantly.
