Pecan Nut Casebearer Model (ACL): The pecan nut casebearer (PNCB) is a key pest of pecans in Texas. Larvae of the first summer generation attack pecan nutlets in May and June and can ruin the entire crop in some years. The purpose of the PNCB model is to aid the grower in deciding when to treat for this pest. The prediction model uses degree days as an indicator of insect development. The model uses historical daily temperature data and current year daily temperature data. Generally, predictions made about 7-10 days before the first significant nut entry or "spray day" give an accurate prediction if current temperatures are used. This model should be used in conjunction with field scouting for maximum effectiveness. In most circumstances, the model prediction is superior to relying on an average calendar date for making treatments.
Location List Editor (ACK): This program allows the user to establish and edit a "list" of filenames, start dates, and descriptions. For instance, a list containing the file names of 10 weather data files along with appropriate start dates and descriptions can be established to allow 10 separate predictions to be completed in a batch.
Weather Data Editor (ACJ): This program is a data entry and storage utility for anyone who needs weather data. Data elements included in the editor were selected as relevant or necessary for use with a variety of insect pest prediction models and crop growth models. However, the weather data can be used for any purpose that requires the same weather data elements.
