An experiment conducted in Iowa, USA, during 1999 and 2000 aimed at (1) predicting the seasonal and site-specific risk of Stewart's disease (SD) of maize, caused by Pantoea stewartii, in the Midwest Corn Belt using geographic information systems (GIS), (2) determining the population dynamics of Chaetocnema pulicaria (SD vector) using yellow sticky cards and sweep nests, and (3) studying the population dynamics of SD-infested C. pulicaria using ELISA.
