Successful implementation of integrated pest management strategies requires accurate prediction of pest phenology. Because plants and insects exhibit temperature-dependent development, biological calendars based on plant phenological sequences can be user-friendly alternatives to degree-day models for predicting pest phenology. The primary objectives of this research were (1) to compare the accuracy of degree-day models and calendar date predictions of pest activity to determine if increased accuracy can be attained with customized species-specific models, or if one standardized model, such as that used by The Ohio State University Growing Degree-Day and Biological Calendar Website, can accurately predict large pest complexes; and (2) analyze data from The OSU Phenology Garden Network to assess consistency from location-to-location and year-to-year of phenological sequences for use as biological calendars for predicting pest activity.A standardized degree-day model, customized degree-day model, and averaged calendar date model were developed for 43 arthropod pest species based on five years of data. ANOVA found no difference in the relative accuracy of the models based on the deviation of their predictions from actual date of occurrence in 2002. The standardized model most accurately predicted 28 of the 45 phenological events. To further assess user-friendly prediction tools, The OSU Phenology Garden Network was established in 2004. The network consists of 34 replicate garden...
