Nantucket Pine Tip Moth Phenology and Timing of Insecticide Spray Applications in the Western Gulf Region

摘要

The Nantucket pine tip moth, Rhyacionia frustrana (Comstock) (Lepidoptera: Tortricidae), is a common pest of pine plantations throughout the Southern United States. The objectives of this study were to predict the phenology of R. Frustrana populations throughout the Western Gulf region, and to provide optimal spray periods for locations that have three or four generations annually. The thermal requirements necessary to complete a generation were obtained from published data, and used in conjuction with historical temperature data to model phenology throughout the region. This paper serves as a companion to a previously published work for the Southeastern United States (Fettig and others 2000a), and thus completes phenology and optimal spray period description for R. frustrana througtout the Southern United States.
