Actividad biológica de hongos entomopatógenos sobre Premnotrypes vorax Hustache (Coleoptera: Curculionidae)

Abstract: El gusano blanco (Premnotrypes vorax Hustache) ocasiona pérdidas considerables en el cultivo de la papa, las cuales pueden llegar hasta el 100% dependiendo del nivel de infestación y manejo del cultivo. El objetivo del presente estudio fue determinar el efecto individual y combinado de dos aislamientos autóctonos de Beauveria spp. en comparación con dos bioplaguicidas a base de Metarhizium anisopliae y Beauveria brongniartii, sobre P. vorax en condiciones de campo. Se empleó el Diseño Completamente al Azar, co… Show more

“…Entomopathogenic fungi showed a dual behavior in their passage from laboratory to field: B. bassiana improved its effectiveness, while L. lecanii decreased it. The improvement of B. bassiana agrees with 46,53 who observed efficiency of B. bassiana isolates in the control of Premnotrypes vorax, both in vitro and in field conditions. However, contrasts with the results reported by 54 .…”

“…Treatment with the fungus L. lecanii did not have statistically significant differences with water. www.nature.com/scientificreports/ Modifying the habitat of pests through pruning is positioned as a successful practice included in good agricultural practices 44,45 point out that in Venezuela, the combination of pruning with the release of biological controllers is a frequent practice in approximately 6% of the guava producers in the country, while 46 demonstrated that the combination with entomopathogenic fungi had a synergistic effect that potentiated the lethality of those formulated against Premnotrypes vorax larvae in potato. However, the study of cultural methods associated with entomopathogenic fungi has focused more on the virulence of the strains used than on the discernment of the mechanisms that allow synergies.…”

“…La actividad microbiana se refiere a los cambios que se expresan en la actividad de los microorganismos, en el caso de M. anisopliae, las investigaciones han incluido la actividad biológica de este microorganismo cuando se combina con aceites esenciales (Rosas-García et al, 2018), el análisis de la actividad enzimática de proteasas obtenidas a partir de M. anisopliae (St Leger et al, 1999;Shah et al, 2005), su actividad antifúngica y fúngica , insecticida (Charnley, 1991) y biológica sobre diversas plagas como son el gusano blanco (Premnotrypes vorax Hustache) (Villamil et al, 2016), la araña roja (Tetranychus evansi Baker & Pritchard) (Azandémè -Hounmalon et al, 2018), la polilla de la papa (Phthorimaea operculella Zeller) (Khorrami et al, 2018), o la rizosfera (Meyling y Eilenberg, 2007), solo por mencionar algunos ejemplos.…”

“…Los rendimientos en el cultivo de la papa Solanum tuberosum L. en Colombia se reducen por la incidencia de insectos plaga, entre los cuales se destaca el gusano blanco de la papa Premnotrypes vorax (Hustache, 1933) (Coleoptera: Curculionidae), el cual muestra niveles de infestación en las áreas cultivadas y puede presentar dificultad para ser controlado, debido al desarrollo de su ciclo biológico a nivel del suelo y rizosfera (Villamil et al 2016).…”
