Technical Abstract: Bean pod mottle virus (BPMV) impacts yield and seed quality. BPMV is vectored primarily by the bean leaf beetle (Cerotoma trifurcata) in Ohio. A 2-year experiment was carried out at two locations in Ohio to determine if resistance to insect feeding reduces disease incidence and spread in soybeans. The experimental design was a split-plot with four repetitions, five host genotypes (Resnik, Williams 82, Troll, HC94-24, and HC95-15), and two inoculum levels. The incidence of BPMV was assessed twice during each year (at growth stages R2 and R7) using ELISA, and data was analyzed using a generalized linear mixed model. Resnik and Williams 82 were the most susceptible, with the highest disease levels, whereas HC94-24, HC95-15 and Troll had much lower levels of incidence. There was a higher incidence of BPMV infection in plots with the higher inoculum level. There was also a positive correlation of disease incidence to initial inoculum level.
