Presence-Absence Sampling Plans for Stink Bugs (Hemiptera: Pentatomidae) in the Midwest Region of the United States.

摘要: Stink bugs represent an increasing risk to soybean production in the Midwest region of United States. The current sampling protocol for stink this is tailored population density estimation and thus more relevant research purposes. A practical decision-making framework with efficient effort management herbivorous needed. Therefore, a binomial sequential plan was developed region. total 146 fields were sampled across 11 states using sweep nets 2016, 2017, 2018. plans combinations five tally thresholds at two proportion infested action identify those that provided best outcomes. Final assessment operating characteristic curves each indicated threshold 3 per 25 sweeps, 0.75 0.95 corresponding 5 10 optimal balance between highest probability correct decisions (≥ 99%) lowest incorrect (≤ 1%). In addition, average sample size both (18 12 sets respectively) lower than other proposed plans. can reduce number units required achieve decision, which important because it potentially risk/cost
