Field experiments were conducted in Stoneville, MS, to determine the impact of soybean planting date and maturity group on stink bug (Heteroptera: Pentatomidae) populations. Maturity group IV and V soybeans were planted on three planting dates in 2003 and 2004. Planting dateswere lateMarchÐearlyApril, lateAprilÐearlyMay, and lateMayÐearly June. Plotswere sampled weekly with a standard 38.1-cm-d...
