Climatic characterization of the wheat streak mosaic virus (WSMV) pathology system and its vector Aceria tosichella Keifer using a Geographical Information System (GIS)

Abstract

Abstracts del XXIV ANNUAL SCIENTIFIC MEETING, celebrado del 8-10 de noviembre 2007, en Tafí del Valle, Tucumán, Argentina.In Argentina, the Wheat streak mosaic virus (WSMV) disease has been present since 2003, when it was detected for the first time in the districts of Marcos Juárez and Jesús María, province of Córdoba. Since then, the disease has been rapidly expanding. This study was undertaken for the purpose of characterizing through a geographical information system (GIS) the areas where the disease was detected up to the present. Data were used for 28 sites where virosis was detected during the 2003-2006 period. FloraMap 1.02 software was used to characterize the sites. Maximum and minimum altitudes recorded were 1280 and 30 m above sea level respectively. Maximum and minimum average ambient temperatures (AAT) were 27.9ºC and 6.1ºC respectively. Maximum and minimum average environmental pressure (AEP) was 239 mm and 2 mm respectively. All sites had a dry season lasting from 6 to 11 months. These results will contribute to an epidemiological study by providing data on climatic features.Peer reviewe
