| description |
The use of fungi and bacteria with pathogenic capacity towards insects is considered a sustainable agroecological alternative for efficient pest control, as they are microorganisms of easy production in industrial scale, formulation and use. Therefore, the objective was to evaluate four entomopathogenic formulations in the control of Brevicoryne brassicae L., a key pest of cabbage (Brassica oleracea L.), in a randomized complete block design with 4 treatments, plus an absolute control and 4 replicates. The variables evaluated were the number of dead and live aphids per plant and the number of infested plants. The commercial formulations Biosafe, BesT-K, Metarrizo and Yurak containing strains of Bacillus subtilis, Bacillus thuringiensis var kurstaki (Btk), Metarhizium anisopliae and Bauveria bassiana respectively, are the ones that were used by spray application to the crop in two seasons: planting, season August-December 2019 and August-December 2021. Among the results, M. anisopliae was recorded with up to 91.11 % efficiency, followed by B. bassiana with 89.50 % and Bs with 79.38 % in the reduction of populations under field conditions. In the laboratory, Btk and M. anisopliae reached 100 % mortality in a period of seven days, so it is concluded that in the medium term, entomopathogenic fungi in the field are more efficient in aphid control; however, in controlled conditions Btk is also efficient. |

Los formulados comerciales Biosafe, BesT-K, Metarrizo y Yurak que contenían cepas de Bacillus subtilis, Bacillus thuringiensis var kurstaki (Btk), Metarhizium anisopliae y Bauveria bassiana, respectivamente, son los que fueron utilizados mediante la aplicación por aspersión al cultivo en dos épocas de siembra, temporada agosto-diciembre 2019 y agosto-diciembre 2021. Entre los resultados se registró al M. anisopliae con hasta 91,11 % de eficiencia, seguida por B. bassiana con 89,50 % y Bs con 79,38 % en la reducción de las poblaciones en condiciones de campo; en laboratorio el Btk y M. anisopliae alcanzaron el 100 % de mortalidad en un lapso de siete días, por lo que se concluye que a mediano plazo los hongos entomopatógenos en campo resultan ser más eficientes en el control del pulgón, sin embargo, en condiciones controladas el Btk también es eficiente.Universidad Central del Ecuador2024-01-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/499410.29166/siembra.v11i1.4994Siembra; Vol. 11 No. 1 (2024); e4994Siembra; Vol. 11 Núm. 1 (2024); e49942477-88501390-892810.29166/siembra.v11i1reponame:Revista Siembrainstname:Universidad Central del Ecuadorinstacron:UCEspahttps://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/4994/7228https://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/4994/7242Derechos de autor 2024 Agustina Valverde- Rodríguez, Antonio Cornejo y Maldonado, Nalda Miguel Villanueva, Miltao Edelio Campos Albornozhttps://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccess2024-01-15T16:14:36Zoai:revistadigital.uce.edu.ec:article/4994Portal de revistashttps://revistadigital.uce.edu.ec/Universidad públicahttps://uce.edu.ec/**Ecuador*2477-88501390-8928opendoar:*2024-01-15T16:14:36Revista Siembra - Universidad Central del Ecuadorfalse |
