Resumo: O interesse pelo controle biológico de nematóides vem aumentando ano após ano, estimulado pelas crescentes restrições ao uso de agrotóxicos. Entre os agentes do controle biológico de nematóides, os fungos predadores vêm se destacando, dada a facilidade de crescimento em meios artificiais e substratos diversos e a comprovada eficácia. No presente estudo, confirmou-se que espécies de Arthrobotrys e de Monacrosporium estão entre os fungos nematófagos mais comuns nos solos do Brasil. Esses fungos crescem em subprodutos da agroindústria, potencializando a formulação desses agentes a baixo custo e pode tornar-se o recurso mais vantajoso para o manejo de nematóides em cultivos de hortifrutigranjeiros em volta de centros urbanos. Bagaço de cana misturado com farelo de arroz, na proporção de 2:1, é um substrato adequado à formulação de fungos nematófagos. Para o cultivo de alface, uma única aplicação, antes do plantio, é suficiente para o manejo dos nematóides. A adição de formulações dos fungos ao substrato para a produção de mudas pode facilitar a utilização desse recurso, e formulações contendo mais de uma espécie com habilidades predatórias diferentes, incluindo parasitos de ovos, podem ser mais eficazes que formulações de uma única espécie. A especificidade dos fungos dificulta o comércio de formulações desses agentes, dado o risco de comprometimento à credibilidade dos produtos, se formulações não-específicas para os nematóides que ocorrem em certas áreas, forem utilizadas. Por conseguinte, as formulações desses agentes são mais adequadas para a distribuição assistida, já que os nematóides que ocorrem nos locais onde serão empregadas, podem ser previamente identificados. / Abstract: The interest in the biological control of nematodes is increasing year after year, stimulated by the increasing restrictions to the use of chemical defensives. Among the agents for the biological control of nematodes, the predators fungi have become the group of higher interest since they grow easily on different kinds of material and they also present known efficacy. In the present study, it was demonstrated that species of Arthrobotrys and Monacrosporium are among the most common nematophagous fungi in Brazilian soils. These fungi grow on by-products of the agroindustry, making formulations of these agents of low cost and can become the most advantageous resource for the nematode control in vegetable production areas around urban centers in Brazil. Sugar cane bagasse mixed with rice bran in the ratio of 2:1 is an adequate substratum for the formulation of nematophagous fungi. For the lettuce culture, only one application, before the planting date, is enough for the control of nematodes. The addition of fungi to the substratum for the production of seedlings in nurseries can facilitate the use of this resource. Formulations containing more than one species with different predatory abilities, including egg parasites, can be more efficient than formulations with only one species. The specificity of the fungi makes difficult the commerce of formulations of these agents, since the risk of unsuccessful use can put down the credibility on the products, if non-specific formulations for the nematodes that occur in certain areas are used. Therefore, the formulations of these agents are more suitable for attended distribution, since the nematodes that occur in places where the formulation will be used can be previously identified. / Orientador: Jaime Maia dos Santos / Coorientador: José Carlos Barbosa / Banca: Clélia Aparecida Iunes Lapera / Banca: Marineide Mendonça Aguillera / Banca: Carlos Amadeu Leite de Oliveira / Banca: Júlio César Galli / Doutor
