Tufted apple budmoth (Lepidoptera: Tortricidae): Simulation of postdiapause development and prediction of spring adult emergence in North Carolina
Environmental Entomology 17 (2), 271-274
Abstract: In-orchard temperatures and pheromone trap catch data for 21 orchard-year (1976-80) combinations were used to compare the accuracy of physiological time models in simulating and predicting male spring emergence of the tufted apple budmoth, Platynota idaeusalis (Walker), in North Carolina apple orchards. By starting model simulations at the date in which larval postdiapause development was calculated to begin, linear (degree-day) and nonlinear models were accurate within ±1 wk in simulating spring flight peaks for 19 and 20 of the 21 orchard-year combinations, respectively. Nonlinear models predict the male spring flight peaks with an accuracy of ±1 wk simulated 5-22 d in advance by using actual orchard temperatures during the first 70% Postdiapause development of P. idaeusalis and then using 5-yr (1976-80) average hourly orchard temperatures thereafter.
