| the entomopathogenic potential of aspergillus spp. in mosquitoes vectors of tropical diseases. | eleven strains of the most frequent aspergillus species found in a survey of brazilian mosquitoes collected in the states of minas gerais and rio de janeiro, brazil, were used for bioassays in second-stage larvae of aedes fluviatilis and culex quinquefasciatus. aspergillus ochraceus, a. kanagawaensis and one strain of a. sulphureus were most effective, causing mortality in at least 80% of the larvae of the two mosquito species tested. variations in entomopathogenic capacity were observed in the ... | 2001 | 11314246 |
| ochratoxigenic fungi associated with green coffee beans (coffea arabica l.) in conventional and organic cultivation in brazil. | the genera aspergillus comprises species that produce mycotoxins such as aflatoxins, ochratoxins and patulin. these are cosmopolitan species, natural contaminants of agricultural products. in coffee grains, the most important aspergillus species in terms of the risk of presenting mycotoxins belong to the genera aspergillus section circumdati and section nigri. the purpose of this study was to assess the occurrence of isolated ochratoxigenic fungi of coffee grains from organic and conventional cu ... | 2013 | 24294225 |
