| description | Wild species of the genus Manihot offer a valuable and potential source of resistance genes for the control of the majority of insect pests of cassava (Manihot esculenta). Recently, this characteristic has being exploited to develop strains resistant to pests and diseases through inter-specific crosses with wild Manihot species. In order to find new sources of resistance in Manihot species, two wild Brazilian species, M. flabellifolia and M. peruviana, were evaluated and compared to commercial genotypes of M. esculenta to determine potential resistance against three of the major cassava pests in the Americas, Africa and Asia: the mite Mononychellus tanajoa, the mealybug (Phenacoccus herreni) and the whitefly (Aleurotrachelus socialis). The research was carried out at CIAT, Palmira, under controlled conditions (25±5 ºC, 60±10 RH, 12L/D) using screening and bioassay methodologies assisted by controlling infestation and damage levels. The results showed that the genotypes M. flabellifolia (444-002) and M. peruviana (417-003 and 417-005) exhibited highest levels of resistance against M. tanajoa and A. socialis, while the genotypes M. flabellifolia (444-002) and M. peruviana (417-003) showed middle levels of resistance against P. herreni. The importance of these sources of resistance is discussed in light of the diversity conservation and host plant resistance programs and a component of integrated pest management. |

Las especies silvestres del género Manihot ofrecen una fuente potencial de genes de resistencia para el control de la mayoría de insectos plaga de yuca (Manihot esculenta). Recientemente, esta característica ha sido aprovechada para el desarrollo de variedades resistentes a plagas y enfermedades a través de cruces inter-específicos con especies silvestres de Manihot. Con el objetivo de buscar nuevas fuentes de resistencia en especies de Manihot, se evaluaron y compararon dos especies silvestres brasileras, Manihot flabellifolia y M. peruviana, frente a genotipos comerciales de M. esculenta, para determinar su potencial de resistencia a tres de las principales plagas de yuca en las Américas, Africa y Asia: el ácaro Mononychellus tanajoa, el piojo harinoso (Phenacoccus herreni) y la mosca blanca (Aleurotrachelus socialis). La investigación se realizó en CIAT, Palmira, bajo condiciones controladas (25±5 ºC, 60±10 HR, 12L/D) utilizando una metodología de tamizados y bioensayos asistida por escalas de infestación y daño. Los resultados mostraron que los genotipos de M. flabellifolia (444-002) y M. peruviana (417-003 y 417-005) exhibieron altos niveles de resistencia frente a M. tanajoa y A socialis, mientras, el genotipo de M. flabellifolia (444-002) y M. peruviana (417-003) presentaron niveles intermedios de resistencia a P. herreni. Se discute la importancia de estas fuentes de resistencia a la luz de los programas de conservación de la diversidad y de la resistencia de planta hospedera como un componente del manejo integrado de plagas. 2007 2014-10-02T08:33:41Z 2014-10-02T08:33:41Z Journal Article https://hdl.handle.net/10568/44383 es Open Access |
