MOTA, Marcelo de Andrade; CAMPOS, Artur Kanadani and ARAUJO, Jackson Victor de. Biological control of helminth parasites of animals: current stage and future outlook. Pesq. Vet. Bras. [online]. 2003, vol.23, n.3, pp. 93-100. ISSN 0100-736X. http://dx.doi.org/10.1590/S0100-736X2003000300001.
Biological control is a non-chemical alternative method with its main goal to reduce the amount of parasite population using natural antagonists. The administration of nematophagous fungi to animals has been considered an alternative in gastrointestinal helminthiasis prophylaxis. The nematophagous fungi produce trap-shaped structures, which are responsible for capturing and destroying the free-living stages of nematodes. The genera Arthrobotrys, Duddingtonia and Monacrosporium has been shown efficacy in laboratory and field experiments against cattle, equine, ovine and swine parasites. Several fungi formulations have been evaluated, but there is so far no commercial product available. The association of research groups with industry could improve the successful implementation of this control method.
