Resumo: Black spot is the major papaya foliar fungal disease, being its chemical control necessary to achieve an economic commercial production. Alternative control methods, concerning fungicides, are necessary for the sustainable production of higher quality papaya fruits. Among them, biological control lacks basic studies. This study aimed to determine the proper temperature conditions for in vitro mycelial growth and sporulation of hyperparasites fungi isolated from Asperisporium caricae in papaya, which are potential biocontrol agents. A total of 18 fungal isolates (eight from Hansfordia pulvinata and ten from Acremonium spp.) were grown on PDA medium, at 15 ºC, 20 ºC, 23 ºC, 25 ºC, 27 ºC and 30 ºC, under a 12-hour photoperiod. For H. pulvinata isolates, mild temperatures around 21 ºC result in maximum mycelial growth and sporulation. For Acremonium spp. isolates, the optimum temperature for mycelial growth and sporulation occurs at 20-25 ºC.

Medidas de controle alternativas aos fungicidas são necessárias para a produção sustentável de frutos de mamão de melhor qualidade. Objetivou-se, neste trabalho, determinar as condições de temperatura adequadas ao crescimento micelial e à esporulação in vitro de fungos hiperparasitas do agente causal da pinta-preta do mamoeiro, potenciais agentes de biocontrole. Foram avaliados 18 isolados fúngicos (oito de Hansfordia pulvinata e dez de Acremonium spp.), cultivados em meio BDA, às temperaturas de 15 ºC, 20 ºC, 23 ºC, 25 ºC, 27 ºC e 30 ºC, sob fotoperíodo de 12 horas. Observou-se, para isolados de H. pulvinata, que temperaturas amenas (em torno de 21 ºC) propiciam máximas de crescimento micelial e esporulação. Para os isolados de Acremonium spp., o ponto ótimo para crescimento micelial e esporulação ocorre no intervalo de 20-25 ºC.Escola de Agronomia - Universidade Federal de Goiás2015-03-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/29774Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 1, Jan./Mar. 2015; 73-81Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 1, jan./mar. 2015; 73-81Pesquisa Agropecuária Tropical; v. 45, n. 1, jan./mar. 2015; 73-811983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/29774/18168Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessVivas, Janieli Maganha SilvaVivas, MarceloSilveira, Silvaldo Felipe da2020-07-13T16:08:50Zoai:ojs.revistas.ufg.br:article/29774Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:07.063063Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
