App Summary

Midwest Stink Bug is a reference tool for farmers and homeowners to identify and report invasive stink bugs, which pose an increasing risk to agriculture in the region. The associated research established an efficient sampling plan for making pest management decisions, developing a framework that achieved a high probability of correct decisions (≥99%) while minimizing incorrect ones (≤1%). The authors conclude that such efficient identification and management strategies can help reduce the risk and costs associated with agricultural stink bug infestations.

Detailed Description

Functionality & Mechanism

The system facilitates identification of common Midwestern stink bugs through a high-resolution image library and a side-by-side comparison interface. This visual reference tool enables differentiation between invasive agricultural pests and beneficial native species. An integrated reporting module captures user submissions of suspected invasive insects and transmits the data directly to designated state agencies. The interface is engineered for rapid field use to support timely pest management and regional monitoring efforts by agricultural producers and homeowners.

Evidence & Research Context

  • Stink bugs represent a significant and increasing risk to key agricultural outputs, particularly soybean production, in the Midwest region of the United States.
  • The associated research highlights a need for practical, efficient decision-making frameworks for on-farm pest management, as traditional sampling protocols are often designed for research.
  • Optimized binomial sequential sampling plans have been developed to reduce the number of sample units required to achieve a correct management decision with high probability (≥99%).
  • By enabling rapid species identification, the app serves as a foundational tool supporting the initial step required for implementing these evidence-based pest management protocols.

Intended Use & Scope

This application is designed for agricultural producers, crop advisors, and homeowners as a field-based visual identification aid. Its primary utility is to facilitate the differentiation of invasive from native species and streamline reporting. The tool does not provide pest management recommendations or action thresholds; users should consult local agricultural extension services for treatment guidance.

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

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

New App for Midwest Farmers: Midwest Stinkbug Assistant

The University of Minnesota Extension IPM Program developed Midwest Stink Bug Assistant to help Midwest farmers identify and manage stink bug pests, partnering with the Minnesota Invasive Terrestrial Plants and Pests Center and Purdue University. The free app provides identification tools and management guidance for both iOS and Android platforms.

Keep an eye out for the brown marmorated stink bug, and yes, there's an app for that

The University of Minnesota Extension and Purdue University developed the Midwest Stink Bug app to better track the invasive brown marmorated stink bug across Minnesota, using high-resolution photos to help users distinguish it from similar species. "The whole reason behind the app is because we're trying to figure out where this new stink bug occurs in Minnesota," said Bob Koch, a U Extension entomologist. Reports from the public feed into a larger regional monitoring system to track the pest that threatens crops and has caused millions in agricultural losses on other coasts.

App helps identify invasive stink bug before it hurts crops

University of Minnesota Extension and Purdue University developed Midwest Stink Bug to help researchers identify the invasive brown marmorated stink bug before it spreads to commodity crops, using high-quality illustrations and photo reporting functions. "The brown marmorated stink bug has caused millions of dollars in crop losses in both the East and Pacific Northwest and we want to avoid that here," said Extension entomologist Bill Hutchison. The free app targets farmers, gardeners and crop consultants with funding from the Minnesota Invasive Terrestrial Plants and Pests Center.
