• Pest status and management of stink bugs (Hemiptera: Pentatomidae) in field corn in the Southeastern United States

  Journal of Integrated Pest Management · 2025-01-01 · 1 citations

  articleOpen access1st authorCorresponding

  Abstract Stink bugs (Hemiptera: Pentatomidae) are the most important economic pests of field corn (Zea mays L.) in the southeastern United States. The most common pest species include the brown stink bug, Euschistus servus (Say), green stink bug, Chinavia hilaris (Say), and southern green stink bug, Nezara viridula (L.). Stink bugs are highly mobile and feed on a wide range of crops and wild hosts across the highly fragmented southeastern landscapes. Because of their strong dispersal ability and the sporadic nature of their occurrence in corn, effective monitoring and implementation of control tactics can be challenging to prevent yield losses in field corn. This article provides an overview of the current literature on key stink bug species in the southeastern United States associated with corn production. A key focus of this review is on the seasonal dynamics of stink bugs in southeastern agroecosystems as related to their pest status in field corn. We discuss the suite of available integrated pest management practices for stink bugs and suggest areas for developing improved strategies in the future.

• MyIPM smartphone applications—tools to increase adoption of integrated pest management

  Journal of Integrated Pest Management · 2025-01-01

  articleOpen access

  Abstract Global agricultural productivity faces significant challenges due to pest-related crop losses, and while integrated pest management (IPM) is a sustainable approach to mitigate pest risks, it is also inherently complex, which limits its implementation and adoption by farmers and pest management professionals. This article provides an overview of the MyIPM series of smartphone applications (apps), designed to facilitate IPM adoption by providing comprehensive pest management recommendations, covering diseases, arthropods, and weeds for multiple US commodities. Key features of the apps include high-resolution images for accurate pest identification, non-chemical integrated management information, detailed life cycle and epidemiology information, a pesticide search bar, and interactive tables allowing active ingredients and trade names to be sorted by multiple characteristics, including modes of action for easier implementation of resistance management tactics. The MyIPM apps complement traditional Extension outreach methods, offering portable access to a wealth of pest management information. In addition, the article highlights 3 practical examples—managing blossom blight and brown rot of peach caused by Monilinia sp.; addressing sugarcane aphids, Melanaphis sorghi (Theobald), in grain sorghum; and managing urban pests in Hawaii and postharvest quarantine of Hawaiian crops for export—demonstrating how the MyIPM apps streamline IPM decision-making for a diverse group of farmers and pest management professionals. Overall, the MyIPM series of apps provides a valuable tool for modern agriculture, offering users a wealth of IPM knowledge at their fingertips, and supporting the adoption of more sustainable and effective practices.

• Stink bug species composition and risk of economic damage in the southeastern soybean cropping systems

  Environmental Entomology · 2025-11-14 · 4 citations

  articleOpen access

  Stink bugs (Hemiptera: Pentatomidae) have emerged as an important pest species complex in soybean production systems across the southeastern United States. Changing cropping practices and climatic conditions are reshaping the stink bug communities in the region. Understanding community differences will be important to tailor integrated pest management programs sensitive to variation in species composition. In this 3-year study (2022-2024), we characterized stink bug diversity and abundance in 154 commercial soybean fields distributed across 3 soybean-producing ecoregions (Coastal Plain, Piedmont, and Mountains) in 2 southeastern states, North Carolina and Virginia. Standardized 25-sweep samples were collected at 10 locations per field during the soybean reproductive stages. Field-level samples were used to evaluate the probability of exceeding the recommended economic threshold for damage. We observed differences in stink bug community composition and spatial variation in the distribution of common stink bug species across the ecoregions. Additionally, the risk of soybean fields exceeding the recommended economic threshold differed across the ecoregions, with the Mountain region at the greatest risk. This result highlights the importance of regionally specific scouting and management recommendations that are sensitive to species composition differences. This work also provides a benchmark to assess range shifts of stink bug species in North Carolina and Virginia.
