Utah TRAPs: Alerts for Pests

Functionality & Mechanism

Developed by Utah State University, Utah TRAPs is a decision-support system that integrates real-time meteorological data with pest phenology models. The interface leverages data from over 95 weather stations to generate location-specific recommendations. Upon selecting a site and target pest (e.g., codling moth), the system computes degree-day accumulations and displays current weather conditions, pest emergence forecasts, and treatment timing advisories. Data is visualized through graphs detailing historical and projected pest activity and weather patterns.

Evidence & Research Context

• The system was developed as a decision-aid tool by the Utah State University Integrated Pest Management Program and the Utah Climate Center to facilitate improved pest management, frost protection, and irrigation scheduling.
• The core mechanism calculates degree-day (DD) accumulation to model pest development, enabling management actions to be synchronized with pest biology rather than fixed calendar dates.
• Published management guides for commercial and home orchards in the Western U.S. incorporate the tool for timing interventions against key pests such as Cydia pomonella (codling moth).
• The system provides distinct configurations (e.g., "Fixed Biofix," "Trap Biofix") to accommodate different user contexts, such as home growers without pheromone traps or commercial producers with site-specific monitoring data.

Intended Use & Scope

This tool is designed for commercial agricultural producers, home orchardists, and crop consultants as a decision-support system for integrated pest management. Its primary utility is to optimize the timing of interventions using phenological models and real-time weather data. The system provides guidance and is not a substitute for professional agricultural consultation or adherence to local regulations.
