Nematophagous fungi can feed on nematodes under nutrient-poor conditions. They live in the soil and their study is important because of their possible use in the biocontrol of phytoparasitic nematodes. These fungi can be cultivated in the laboratory using different media and substrates, making them potential agents for agricultural use in tropical environments. The objective was to review recent scientific advances in the ecological interactions of nematophagous fungi and their prey, with emphasis on their use as biological controllers. Given the importance of their interactions in the soil, diversity, abundance, dispersal, and colonization of different types of habitats, these fungal microorganisms can be specialists or generalists in the predation of nematode populations in their various stages (egg, juvenile or adult). The different scientific advances and applications of predatory fu...

Root-knot nematodes are detrimental to agricultural crops and hard to control once established in the field. The objective of this research was to evaluate the growth, sporulation, and capture in vitro of asexual fungi against Meloidogyne sp. Molecular identification of the asexual fungi included in the study was performed by sequencing the ITS1 region of rDNA. The growth and sporulation of Arthrobotrys sp., Dactylellina sp. and Dactylaria sp. was evaluated in five culture media and two types of substrates (rice husks and ground corn). For the evaluation of attraction and capture of the nematodes, second stage juveniles of Meloidogyne sp. All the evaluated fungal isolates grew and sporulated in the culture media and substrates. The fungi Arthrobotrys sp. (C19-1-1) and Dactylellina sp. (C19-48) showed greater effectiveness in attracting and capturing Meloidogyne sp. The evaluated fungal i...
