Desarrollo de preformulados a base de Nomuraea rileyi para el control de Spodoptera frugiperda (Lepidoptera: Noctuidae)

Abstract: Nomuraea rileyi es el microorganismo que más frecuentemente se encuentra causando epizootias naturales en campo en larvas de Spodoptera frugiperda en diferentes zonas productoras de maíz en Colombia; sin embargo, en el mercado nacional no existe ningún producto registrado a base de este hongo. Por lo tanto, los objetivos del presente trabajo fueron los de desarrollar un método de producción masiva y desarrollar prototipos de bioplaguicida con una cepa del hongo N. rileyi seleccionada por su actividad para el c… Show more

“…Recently, N. rileyi has been re‐described and changed to M. rileyi according to the molecular characterization by Kepler et al (2014). Natural infection of M. rileyi in the FAW has been reported in several countries (Shylesha et al, 2018; Villamizar et al, 2004). Previous studies reported that M. rileyi isolates were highly virulent to FAW in laboratory conditions (Bosa et al, 2004; Tigano‐Milani et al, 1995).…”

“…All nutritional supplementation proposed herein shorted the culture time of Nm017 to 7 days, traditionally ranging from 10 to 15 days (Devi et al 2001 ; Villamizar et al 2004 ; Caro et al 2005 ; Méndez et al 2010 ; Thakre et al 2011 ; Bich et al 2018 ). During the drying process, the loss of surface water over time caused the volume reduction of the fermentation solid matrix and, probably, the aerial conidia, which made the conidia dustier and less linked to the substrate.…”

“…Values achieved with both media, T2 and T6, were higher than those observed with other commercial entomopathogenic fungus, e . g. , M. rileyi strains growth on a medium rich in soybeans (1.5 × 10 9 conidia g −1 substrate; Caro et al 2005 ), wheat bran enriched with malt soda (3.0 × 10 9 conidia g −1 substrate; Villamizar et al 2004 ), and crushed sorghum (1.4 × 10 9 conidia g −1 substrate; Devi et al 2001 ). Also, Nm017 production presented appropriate biomass yields for commercial entomopathogenic species, like M. anisopliae (27–42.2 g kg −1 ) and B. bassiana (20–40 g kg −1 ) (Keppanan et al 2018 ; Tumuhaise et al 2018 ; Liu et al 2015 ; Pham et al 2010 ; Posada-Flórez 2008 ; Renuka et al 2015 ).…”
