tydeid and triophtydeid mites (acari: tydeoidea) associated with grapevine (vitaceae: vitis spp.) in brazil, with the descriptions of species of prelorryia (andré, 1980) and tydeus koch, 1835.we report on the tydeidae and triophtydeidae associated with grapevine (vitis labrusca l. and vitis vinifera l.) in rio grande do sul state, brazil, and describe a new species of prelorryia, prelorryia labrusca sp. nov., and two new species of tydeus, tydeus manoi sp. nov. and tydeus riopardensis sp. nov. brachytydeus formosa (cooreman), b. podocarpa (baker), neolorryia pandana (baker), tydeus californicus (banks), pretydeus henriandrei kaźmierski and triophtydeus lebruni (andré) are recorded an ...201424943444
diversity of aspergillus section nigri on the surface of vitis labrusca and its hybrid grapes.this study investigated the presence of aspergillus species belonging to aspergillus section nigri on vitis labrusca and its hybrid grapes grown in brazil. the ability of the fungi isolates to produce ochratoxin a (ota) and fumonisin b2 (fb2) as well as the presence of these mycotoxins in the grapes were also studied. eighty-eight samples were collected from the main grape producing states in brazil: rio grande do sul (n=30), pernambuco (n=21), são paulo (n=21) and paraná (n=16). the highest ave ...201829331673
supercritical extraction from vinification residues: fatty acids, α-tocopherol, and phenolic compounds in the oil seeds from different varieties of grape.supercritical fluid extraction has been widely employed in the extraction of high purity substances. in this study, we used the technology to obtain oil from seeds from a variety of grapes, from vinification residues generated in the southern region of the state of rio grande do sul, brazil. this work encompasses three varieties of vitis vinifera (moscato giallo, merlot, and cabernet sauvignon) and two of vitis labrusca (bordô e isabel), harvested in 2005 and 2006. we obtained the highest oil co ...201222593706
