Abstract: The eucalyptus snout beetle (ESB), Gonipterus platensis, is endemic to Australia but has become a major invasive, destructive pest of Brazilian eucalyptus plantations. Efforts to develop insecticides based on entomopathogenic fungi against ESB are limited by the lack of known virulent strains. We therefore explored the virulence of indigenous Brazilian strains of major entomopathogenic fungi?Beauveria spp. and Metarhizium anisopliae?against ESB adults. We found widely varying virulence and later capacities for conidial production on infected adult cadavers. Two strains stood out, B. bassiana IBCB-240 and M. anisopliae IBCB-364, as especially lethal for ESB adults under laboratory conditions, sporulated abundantly on infected insects, and also outperformed comparable strains used in commercial mycoinsecticides. Notably, B. bassiana IBCB-240 exhibited lower LT50 values at low inoculum levels (≤ 107 conidia mL−1) and smaller LC50 values than M. anisopliae IBCB-364. Taken together, this study emphasizes natural variation in virulence among indigenous Beauveria and Metarhizium strains against ESB adults and identifies fungal strains with superior lethality to existing commercialized strains for managing this eucalyptus pest in Brazil. |

Abstract A fast method for the simultaneous quantitative determination of 16 phenolic compounds in grape juice by UPLC-MS was developed and validated. Run time was 4.5!min and the method proved to be specific, linear (r > 0.9961), precise (RSD < 5%), accurate (recovery range was under ± 5%) and sensitive with a limit of detection ranging from 0.45 to 35.34!"g L−1 and limit of quantification ranging from 1.35 to 107.08!"g L−1. The validated method was used to characterize 49 grape juice samples which were produced with different grape varieties. Anthocyanins were the compounds present in the highest amounts on the analyzed samples and BRS-Violeta was the cultivar that presented the highest quantity of phenolic compounds in its juice. Exploratory analysis of the obtained results from the characterization of grape juice samples was performed and a tendency to form groups according to the grape variety used in the elaboration of each juice was observed. Results confirmed that the UPLC-MS method is effective and suitable for the determination of phenolic compounds in grape juice.
