Endophytic establishment of Beauveria bassiana and Metarhizium anisopliae in maize plants and its effect against Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) larvae

摘要: The aim of the present study was to evaluate artificial establishment Beauveria bassiana and Metarhizium anisopliae as endophytes in maize plants, its effect controlling fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) larvae. commercial strains B. Bb-18 M. Ma-30 were concentrated at 1 × 108 conidia ml−1, soil drench method used establish them plant parts. biological control assays conducted under laboratory conditions on second fourth larval instars S. frugiperda. colonized roots, stems, leaves tissues. However, a high occurrence obtained roots than stems with 25, 10, 5 isolations, respectively, whereas only acquired roots. Both entomopathogenic fungi caused (100%) mortality instar In addition, killed (87 75%) instars, respectively. fungus highest sporulation rates during study. These results suggest that might contribute sustainable management production Cuba.
