New Limonoids from Dictyoloma vandellianum and Sohnreyia excelsa: Chemosystemat...

Molecular phylogenetic studies separated and united a group of genera that constituted the Spathelia-Ptaeroxylon clade, in which Dictyoloma and Sohnreyia have been included. Our taxonomic interest in the Dictyoloma vandellianum and Sohnreyia excelsa stimulated an investigation of both species searching for limonoids. Leaves from D. vandellianum afforded the new limonoid 1,2-dihydro-1α-hydroxy-8,30-epoxy-cneorin...

Atratividade, consumo e mortalidade de Tuta absoluta (Lepidoptera: Gelechiidae)...

Tuta absoluta é praga chave do tomateiro, causando danos consideráveis à produção. O controle tem sido feito principalmente com inseticidas sintéticos, porém óleos de origem botânica têm-se destacado no controle de artrópodes. Este trabalho teve por objetivo avaliar os efeitos do óleo de Melia azedarach sobre T. absoluta, também conhecido por óleo de cinamomo. O óleo extraído de M. azedarach foi diluído em 50,0...

Compatibility of polymers to fungi Beauveria bassiana and Metarhizium anisoplia...

Stability during storage is a limiting factor in the development and use of bioinsecticides. This study aims to evaluate the compatibility of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana with components used in encapsulated formulations and to evaluate shelf-life in formulations with B. bassiana. Sodium alginate and maltodextrin, hemicellulose, and dimethyl sulfoxide solvents were ev...
