Interpretive Summary: Several different sampling methods for detection of tarnished plant bug densities were tested in Mississippi, Louisiana, Arkansas, and Tennessee. Sweep net and drop cloth sampling methods were about equally efficient but have different biases. Although sweep nets catch many more adults, more nymphs are found on drop cloths. Sweep nets had a stronger correlation with other sampling methods than drop cloths. Dirty blooms were the most efficient indirect sampling method tested and generally generated a recommendation consistent with the other sampling methods. The occurrence of dirty blooms, however, may respond slowly to changes in plant bug numbers (i.e., may be more indicative of previous pest densities than current infestation levels). Dirty squares also provided valuable information about insect densities.
