Stewart's disease of corn, caused by the bacterium Pantoea (Erwinia) stewartii, is an extremely important disease for seed and sweet corn producers. Economic losses can be substantial for both producers. In the seed corn industry, zero tolerance phytosanitary regulations greatly limit the ability of seed corn to be exported from fields where Stewart's disease has been found. One area of research that has been limited in regard to Stewart’s disease is the population dynamics of the corn flea beetle (Chaetocnema pulicaria) vector. The corn flea beetle is the primary mode for acquiring and transmitting P. stewartii, as well as the sole overwintering habitat for the bacterium. More information is needed on the corn flea beetle to help improve management tactics for reducing the risk of Stewart’s disease.
