%X Since the 1990s geminiviruses have emerged as devastating pathogens in tropical and subtropical regions as well as in temperate regions. Recent studies accomplished molecular hybridization-based detection of three begomoviruses infecting soybean and bean crops in Argentina, Bean golden mosaic virus (BGMV), Soybean blistering mosaic virus (SbBMV) and Tomato yellow spot virus (ToYSV). The aims of the present study were to determine incidence and prevalence of the three known geminiviruses in soybean and bean crops in Argentina following the same procedure and to characterize the sites where Bemisia tabaci-geminivirus complex was found based on climate data. The highest incidence values were observed in Salta province. BGMV exhibited the highest prevalence and incidence values in the bean crop, followed by SbBMV. In the soybean crop, SbBMV showed the highest prevalence and incidence values, followed by ToYSV. One hundred and three soybean and bean plots distributed in Argentina, where the Bemisia tabaci-geminivirus complex was detected, were characterized employing a Geographic Information System (GIS). The complex was found in warm and low rainfall areas; these climatic characteristics are consistent with those identified in a previously described model. A map with the probability of occurrence of B. tabaci-geminivirus, based on the climatic characteristics, was obtained. Desde la d谷cada de 1990, los geminivirus han emergido como pat車genos devastadores en regiones tropicales, subtropicales y templadas. En estudios recientes, se ha desarrollado un m谷todo de detecci車n de tres begomovirus infectando cultivos de soja y poroto en la Argentina, Bean golden mosaic virus (BGMV), Soybean blistering mosaic virus (SbBMV) y Tomato yellow spot virus (ToYSV). El objetivo del presente estudio fue determinar la incidencia y prevalencia de estos tres geminivirus y caracterizar los sitios donde se encontr車 el complejo Bemisia tabaci-geminivirus bas芍ndose en datos clim芍ticos. El valor de incidencia m芍s alto se observ車 en la provincia de Salta. BGMV present車 los mayores valores de prevalencia e incidencia en poroto, seguido por SbBMV. En el cultivo de soja, SbBMV present車 los mayores valores de prevalencia e incidencia, seguido por ToYSV. Un total de 103 sitios distribuidos en la Argentina, donde se detect車 la presencia del complejo Bemisia tabaci-geminivirus, fueron caracterizados con un sistema de informaci車n geogr芍fica (SIG). El complejo se encontr車 en zonas c芍lidas y de pocas lluvias; estas caracter赤sticas clim芍ticas son consistentes con las identificadas en un modelo de
