Revista de la Facultad de Agronomía de la Universidad del Zulia https://mail.produccioncientificaluz.org/index.php/agronomia <p>The Journal of the Faculty of Agronomy, Universidad del Zulia is a publication of the Agronomic Research Institute of the Faculty of Agronomy, Universidad del Zulia, published since 1968 and is supported by the Universidad del Zulia, in order to disseminate the results of researchers Venezuelans and other parts of the world, related to the agricultural field. The Rev. Fac. Agron. (LUZ) publishes four issues per year, i. e., every three months, under continuous publication format (rolling pass). , with original and unpublished scientific articles, technical notes, review articles, quick communications, extensive summaries of congresses and scientific meetings related to the agricultural area for the consideration of the Editorial Committee. The journal publishes research products of high scientific quality and promotes the exchange of publications and scientific activity at the agricultural level, in the areas of Plant Production, Animal Production, Food Technology and Socioeconomics. The topics included in these areas are: agrosystem management, environment, agricultural biotechnology, meat science, milk science, rural development, agricultural economics, agricultural entomology, fertilizers, post-harvest physiology, plant physiology, physiology and animal reproduction, pastures and forages, animal and plant genetics and improvement, weeds, animal nutrition, plant pathology, agri-food safety, agri-food systems and soils.</p> en-US agrorevistaluz@gmail.com (Jorge Vilchez Perozo) asistencia@serbi.luz.edu.ve (RevicyhLUZ) Sun, 30 Mar 2025 00:00:00 +0000 OJS 3.1.2.4 http://blogs.law.harvard.edu/tech/rss 60 Biocontrol of Cosmopolites sordidus using entomopathogenic fungi under laboratory conditions, Ecuador https://mail.produccioncientificaluz.org/index.php/agronomia/article/view/43680 <p><em>Cosmopolites sordidus </em>known as the black weevil, is an insect pest of economic importance for Musaceae crops such as bananas and plantain, resulting in production losses due to its damage. One of the alternatives for the management of the black weevil is biological control using entomopathogens that regulate the insect populations in Musaceae plantations. The objective of the research was to determine the action of the entomopathogenic fungi <em>Beauveria bassiana</em>, <em>Metarhizium anisopliae,</em> and <em>Verticillium lecanii</em> on adults of the black banana weevil under controlled laboratory conditions. A completely randomized design was implemented with 8 treatments with the application of the entomopathogens individually and in combinations, as well as a control treatment. The results showed that the treatment with the combination of <em>B. bassiana</em> + <em>M. anisopliae</em> showed the best control of the insect pest with 100 % mortality 10 days after inoculation, followed by <em>B. bassiana</em> with 88 % and 24% control with <em>M. anisopliae</em>, while the treatment with the fungus <em>V. lecanii</em> achieved 32 % control of the black weevil. Entomopathogens are an alternative for the management of the insect pest of Musaceae <em>C. sordidus</em>.</p> Danilo Valdez, Simón Farah, Winston Espinoza, Freddy Veliz, Henry Villon, Liliana Herrera Copyright (c) 2025 Danilo Ramiro Valdez Rivera, Simón Ezequiel Farah Asang, Winston Carlos Espinoza Morán, Freddy Fernando Veliz Piguave, Henry Paul Villon Leoro, Edwin Stalin Hasang Moran, Liliana Herrera Espinoza https://creativecommons.org/licenses/by-nc-sa/4.0 https://mail.produccioncientificaluz.org/index.php/agronomia/article/view/43680 Sun, 30 Mar 2025 00:00:00 +0000
