    Abundance and seasonal prevalence of soybean bugs on vegetation including wild soybean, Glycine soja Sieb. et Zucc, and soybean, Glycine max （L.） Merr., fields were investigated in Kumamoto from 2013 to 2015. Nezara viridula, N. antennata, Piezodorus hybneri and Riptortus pedestris were found in abundance on the surveyed vegetation and fields. The age structure of each bug species on vegetation including wild soybean was similar to that of soybean fields which is suitable as a host of soybean bugs. The nymphal development of each bug species was observed on vegetation including wild soybean as with the soybean fields. These results indicate that the vegetation including wild soybean is available as host plants of soybean bugs as with the soybean fields. The invasion of soybean bugs to surveyed vegetation including wild soybean was later than the soybean fields. The delayed invasion of bugs to vegetation including wild soybean compared to soybean fields, indicates differences in host plant availability and suitability between wild soybean and soybean may affect the host selection of the bugs.
