“…Significant reductions have been observed in the number of third stage larvae developing in cultures of bovine, ovine, or equine faeces exposed to different species of nematophagous fungi including Arthrobotrys oligospora (Granvold et al, 1987(Granvold et al, , 1988(Granvold et al, , 1989Hashmi & Connan, 1989), A. oviformis (Waller & Faedo, 1993), A. tortor and A. musiformis (Gruner et al, 1985), Duddingtonia (Arthrobotrys) flagrans (Bird & Herd, 1995;Larsen et al, 1995aLarsen et al, ,b, 1996, Dactylaria Candida (Gruner et al, 1985), and Geniculifera eudermata (Waller & Faedo, 1993). In addition, Charles et al (1996) reported a significant reduction of Haemonchus contortus larvae in faecal cultures mixed with a large inoculum of Harposporium anguillulae which was isolated in the present study. Dactylaria brochopaga (also isolated in this study) was reported to be a less efficient predator than A. oligospora against Ostertagia ostertagi and Trichostrongylus axei larvae (Pandey, 1973).…”

Two sets of dung-derived organisms from soil routinely fertilized with manure (MA) and soil chemically fertilized (CH) were cultured separately in the laboratory. Baermannized organisms from these cultures were added to 20 g of faeces from strongyle-infected horses to form three treatment groups: (i) no soil organisms; (ii) low inoculum of soil organisms containing all organisms present in a suspension of approximately 100 adult female free-living nematodes; and (iii) high inoculum containing those soil organisms present with approximately 1000 adult female free-living nematodes. Three studies were conducted using MA cultures and faeces containing 50 strongyle epg, CH cultures and faeces containing 1500 strongyle epg, and a mixture of soil organisms from the two cultures (MC) and faeces containing 600 strongyle epg. Within each study, five control cultures and 15 each of low and high inoculum cultures were prepared and incubated at 24 C C and 95% humidity in a climate chamber for 15 days. Parasitic and free-living nematodes were then recovered by the Baermann technique and counted. The numbers of third stage larvae were significantly lower in the high inoculum group compared to controls. The percent reductions in the number of third stage larvae for the low and high inoculum groups were 63.6% and 90.9%, 85.1% and 97.1%, 84.5% and 98.4% for MA, CH, and MC studies, respectively, indicating that mortality increased with the number of soil organisms added to cultures. Examination of the source cultures detected the presence of two species of nematophagous fungi and three genera of free-living nematodes reported to be predacious.

Domestic animals are susceptible to a large number of parasitic diseases, which lead to severe economic losses to livestock industry. So, it is necessary to control parasitic infections in these animals. Control of these helminths is undertaken mostly by anthelmintics, but because of their widespread use there is development of resistance across the globe. However, total dependence on a single method of control has proved to be non-sustainable and cost ineffective in the long term. A combination of treatment and management is necessary to control parasitism so that it will not cause further economic losses to producer as well as to livestock industry. To become practically and ecologically sustainable, parasitic control schemes need to be based on integrated parasite management.

“…Nematode-destroying fungi can be grouped into three: nematode-trapping fungi, the endoparasitic fungi and the fungal parasites of cyst and root-knot nematodes. Most nematopathogenic fungi fall in the group of nematode trapping; they use constricting (active) or non-constricting (inactive) rings, sticky hyphae, sticky knobs, sticky branches or sticky networks at intervals along the length of a widely distributed vegetative hyphal system to trap and kill nematodes by penetration and growth of hyphal elements within the host, for example, Arthrobotrys candida, A. oligospora, Drechmeria coniospora [58], Harposporium anguillulae [59] and Monacrosporium spp. [60].…”

Natural Remedies in the Fight Against Parasites

Parasites (ectoparasites or endoparasites) are a major cause of diseases in man, his livestock and crops, leading to poor yield and great economic loss. To overcome some of the major limitations of chemical control methods such as rising resistance, environmental and health risks, and the adverse effect on non-target organisms, biological control (biocontrol) is now at the forefront of parasite (pests) control. Biocontrol is now a core component of the integrated pest management. Biocontrol is defined as "the study and uses of parasites, predators and pathogens for the regulation of host (pest) densities". Considerable successes have been achieved in the implementation of biocontrol strategies in the past. This chapter presents a review of the history of biocontrol, its advantages and disadvantages; the different types of biological control agents (BCAs) including predators, parasites (parasitoids) and pathogens (fungi, bacteria, viruses and virus-like particles, protozoa and nematodes); the effect of biocontrol on native biodiversity; a few case studies of the successful implementation of biocontrol methods and the challenges encountered with the implementation of biocontrol and future perspectives.
