Three main insect pests were studied, the bean leaf beetle, Mexican bean beetle and soybean aphid. To study bean leaf beetle populations and dynamics, sampling was done in organic soybean fields. The data from this sampling study showed an economic population of bean leaf beetle in organic soybeans. This economic population and high levels of pod injury makes bean leaf beetle a major concern in organic soybean. The next study was designed to determine if there were decreases in plant susceptibility due to organic growing methods using Mexican bean beetle. No difference was found between organically and conventionally grown soybean. The last study looked at the soybean aphid. Samples were taken in organic fields to examine aphid populations and dynamics throughout the seasons. Although hampered due to weather, there were still economic populations of aphids present in organic soybeans. 2008-09-08 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1211938253 http://rave.ohiolink.edu/etdc/view?acc_num=osu1211938253 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
