Predicting the seasonal distribution of fall armyworm in North America using species distribution models.

ABSTRACT:

Background

Species distribution models (SDMs) are widely used in pest management to predict outbreak areas. Migratory pests cause seasonal crop damage through long-distance migration, making it crucial to understand their seasonal activity when estimating outbreak regions. Fall armyworm (FAW), a highly migratory pest, was studied using SDMs to predict its seasonal distribution in the central and eastern USA and explore the environmental factors influencing its distribution.

Results

We used monthly environmental and species distribution data to model each month or season individually. Based on model results, the suitable habitat for FAW expands rapidly in summer, covering most of the central and eastern USA in July and August, and then begins to contract in September. Based o
