Diversity of Auchenorrhyncha (Hemiptera: Cicadellidae: Delphacidae) associated with Vicia villosa in southern Buenos Aires province, Argentina
(2014-06)Among the Hemiptera, the Auchenorrhyncha are well known owing to their phytosanitary relevance since the group includes pathogen vector species able to damage commercial crops. Vicia villosa Roth (Fabaceae) is a fodder ... -
Diversity of Cicadomorpha (Hemiptera: Auchenorrhyncha) in citrus orchards in Northeastern Argentina
(2013-09)Among phytophagous insects, the Cicadomorpha are important economically because they damage crops by sucking plant sap and by transmitting plant pathogens, such as Spiroplasma citri and Xylella fastidiosa to citrus. In ... -
