  • Proactive Resistance Management App Instructional Booklet
    Ellsworth, P.C.; Fournier, A.; Keith, M.; Calvin, W; Brown, A; Dixon, W; King, M.; Rahr, M; University of Arizona (College of Agriculture, Life & Environmental Sciences, University of Arizona (Tucson, AZ), 2025-11-06)
    This instructional booklet provides a concise, field-ready guide to the Proactive Resistance Management (PRM) web tool, a community-based decision-support system developed by the Arizona Pest Management Center to promote proactive insect resistance management. Through short explanatory panels and annotated screenshots, the booklet introduces key concepts such as temporal refuge and Mode of Action (MoA) color families, explaining how users can interpret and apply PRM outputs to support sustainable insecticide stewardship across crops and regions. Designed for one-on-one or small-group teaching in the field, this resource complements the online tool available at PRM.extension.arizona.edu.

  • Cave millipedes of the United States. XVII. A new troglobiotic Nevadesmus Shear, 2009 from an Arizona cave (Diplopoda, Polydesmida, Macrosternodesmidae) with observations on associated fauna and ecology
    Shear, William A.; Pape, Robert B.; Marek, Paul E.; University of Arizona, Department of Entomology (Magnolia Press, 2025-11-20)
    A third species of the macrosternodesmid millipede genus Nevadesmus Shear, 2009 is described from a cave in Tonto National Forest, Pinal Co., southern Arizona, USA. This new species, Nevadesmus superstitiona Shear, Pape & Marek, n. sp. occurs significantly distant from the localities of the two other species, which occur in Nevada. The epigean and hypogean settings of the cave site and remarks on its natural history are provided. Thirty-two animal taxa are present in the cave, including the new millipede. Four other endemic troglobiotic species are present: a scorpion (Pseudouroctonus sp.: Vaejovidae), a terrestrial isopod (Brackenridgia sp.: Trichoniscidae), a silverfish (Speleonycta sp.: Nicoletiidae) and a thread-legged bug (Gardena cf. elkinsi: Reduviidae). A resident population of the tailless whip scorpion (Paraphrynus tokdod: Amblypygi: Phrynidae) is the first record of this family in an Arizona Cave. Tonto National Forest Cave #34 is the second most species diverse cave currently known in Arizona.

  • Crop Evapotranspiration in Organic Lettuce Production as a Water-Saving Strategy under Sensor-Guided Irrigation in the Lower Colorado River Basin
    Mohammed, Ali T. (College of Agriculture, Life & Environmental Sciences, University of Arizona (Tucson, AZ), 2025-11)
    This study was conducted at the University of Arizona, Yuma Agricultural Center, to quantify and compare the seasonal crop evapotranspiration (ETc) of organic and conventional iceberg lettuce under sensor-based and traditional irrigation scheduling, with and without biostimulant applications..

  • Projected Temperature Increase Across the Cotton Belt Region of the United States
    Singh, Bhupinder; Samanta, Sayantan; Ale, Srinivasulu (College of Agriculture, Life & Environmental Sciences, University of Arizona (Tucson, AZ), 2025-10)
    This article outlines projections for maximum and minimum air temperatures averaging across nine selected GCMs under four Shared Socioeconomic Pathways (SSP) scenarios: SSP1-2.6 ("Sustainability" pathway with low greenhouse gas emissions), SSP2-4.5 (moderate future warming), SSP3-7.0 (medium to high level of greenhouse gas emissions), and SSP5-8.5 (high greenhouse gas emissions scenario). The projections are provided for five sites across the US Cotton Belt: Maricopa, AZ; Halfway, TX; Chillicothe, TX; Camilla, GA; and Lewiston-Woodville, NC, where key research and extension centers linked with the University of Arizona, Texas A&M University, Texas Tech University, the University of Georgia, and the University of North Carolina, respectively are located.

  • Arizona Agricultural Enterprise Budgets: Maricopa County’s 2025 Field Crops’ Production Budgets
    Quintero, José H.; Mukherjee, Avik (College of Agriculture, Life & Environmental Sciences, University of Arizona (Tucson, AZ), 2025-10)
    This report estimates the typical economic costs and returns for growing major crops, including alfalfa, barley, corn silage, cotton, sorghum grain, sorghum silage, durum wheat, and winter wheat in Maricopa County, Arizona. The Arizona Agricultural Enterprise Budgets are estimated based on a representative farm and its related cropping operations in a determined location; numbers are reported on a per-unit basis.
