Effect of volatile organic compounds released by Trichoderma spp. or Fusarium oxysporum on the selective attraction of Folsomia candida (Collembola)

The fruit from Physalis peruviana (Uchuva) is a highly valuable exportation product for Colombia due to its sweetness and coloration. However, Uchuva crops are susceptible to be devastated by the fungi Fusarium oxysporum causing great economic losses. As this fungus is very hard to control, it has b...

description The fruit from Physalis peruviana (Uchuva) is a highly valuable exportation product for Colombia due to its sweetness and coloration. However, Uchuva crops are susceptible to be devastated by the fungi Fusarium oxysporum causing great economic losses. As this fungus is very hard to control, it has been proposed as an alternative the use biocontrol agents. We proposed that the combined use of Trichoderma spp. and Folsomia candida (Collembola) could be beneficial for the control of F. oxysporum in Uchuva plants. The aim of our study was to determine if the springtail F. candida is able to discriminate the volatile organic compounds (VOCs) released by F. oxysporum and Trichoderma spp. With a dual choice olfactometer, we tested the attraction of F. candida towards the VOCs released by an isolate of F. oxysporum (pathogenic to Uchuva), T. viridae, T. harzianum and T. longibrachiatum. Our results showed that F. candida was not significantly attracted to or repelled by T. harzianum, T. viridae and F. oxysporum. In contrast, T. longibrachiatum repelled significantly the springtail F. candida. In conclusion, from the point of view of organic volatiles, the use of T. longibrachiatum as a biocontrol agent is recommended for further in vitro experiments to control F. oxysporum. Also, it is suggested to study with more detail how they interact with each other and with soil components because additional sensory cues can be used by springtails to detect the presence of fungi in more complex environments

Sin embargo, los cultivos de uchuva son susceptibles a ser devastados por el hongo Fusarium oxysporum causando grandes pérdidas económicas. Ya que este hongo es muy difícil de controlar, se ha propuesto como una alternativa el uso de agentes biocontroladores. Nosotros proponemos que el uso de Trichoderma spp. y Follonía candida (Collembola) en conjunto puede ser beneficioso para el control de F. oxysporum en plantas de uchuva. El objetivo de nuestro estudio fue determinar si el collembolo F. candida podía discriminar los compuestos orgánicos volátiles (COVs) emitidos por F. oxysporum y Trichoderma spp. Con un olfatómetro de doble elección probamos la atracción de F. candida hacia los COVs emitidos por un aislamiento de F. oxysporum (patógeno de uchuva), T. viridae, T. harzianum, T. longibrachiatum. Nuestros resultados muestran que F. candida no fue atraído o repelido significativamente por T. harzianum, T. viridae y F. oxysporum. En contraste, T. longibrachiatum repelió significativamente al collembolo F. candida. En conclusión, desde el punto de vista de los volátiles orgánicos, el uso de T. longibrachiatum como agente biocontrolador es recomendado para futuros experimentos in vitro para controlar F. oxysporum. Además, se sugiere estudiar con más detalle cómo interactúan entre ellos y con otros componentes de la tierra, ya que estímulos sensoriales adicionales pueden ser usados por los collembolos para detectar la presencia de hongos en ambientes más complejos."--Tomado del Formato de Documento de GradoMicrobiólogoPregrado22 hojasapplication/pdfengUniversidad de los AndesMicrobiologíaFacultad de CienciasDepartamento de Ciencias Biológicasinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaEffect of volatile organic compounds released by Trichoderma spp. or Fusarium oxysporum on the selective attraction of Folsomia candida (Collembola)Trabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPUchuvasFusarium oxysporumTrichodermaCollembolaMicrobiologíaPublicationhttps://scholar.google.es/citations?user=nCoNP_MAAAAJvirtual::16292-10000-0003-3018-6726virtual::16292-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001012053virtual::16292-19868e8c9-c2f8-458f-9d29-ed9d658b59fevirtual::16292-19868e8c9-c2f8-458f-9d29-ed9d658b59fevirtual::16292-1ORIGINALu821204.pdfapplication/pdf1333502https://repositorio.uniandes.edu.co/bitstreams/ba4eeff8-b050-4d69-b22a-842566a970c3/downloada457a950c0327bb51810ea6db2dc4344MD51TEXTu821204.pdf.txtu821204.pdf.txtExtracted texttext/plain36267https://repositorio.uniandes.edu.co/bitstreams/1a93f4c3-f4d9-4b9a-8d11-6266676025ae/download474ffe1ac583b423f6125cb3fdb96bdfMD54THUMBNAILu821204.pdf.jpgu821204.pdf.jpgIM Thumbnailimage/jpeg21562https://repositorio.uniandes.edu.co/bitstreams/acace15b-879c-4a44-a613-7b9c32f67024/download2ee2a00b44851f6864837da6094d7ddbMD551992/39294oai:repositorio.uniandes.edu.co:1992/392942024-03-13 15:41:17.521http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
