Spatiotemporal distribution of the glassy-winged sharpshooter, Homalodisca vitripennis (Hemiptera: Cicadellidae), in a southeastern agroecosystem
Florida Entomologist 105 (4), 280-286
Abstract: The glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), is a generalist xylem feeder insect species and an agricultural pest. In agroecosystems, adults disperse between habitats, foraging on crop and non-crop hosts, oftentimes vectoring a harmful plant pathogen, Xylella fastidiosa Wells et al. (Xanthomonadales: Xanthomonadaceae). Understanding the spatiotemporal dynamics of this species in crops and the surrounding non-crop habitat may lead to improved pest management programs that reduce pathogen transmission. Here, we used 3 yr of trapping data across a southeastern US agroecosystem to characterize spatiotemporal distribution patterns of the glassy-winged sharpshooter in a variety of habitats. Adult glassy-winged sharpshooters were captured weekly on yellow sticky cylinder traps. Spatial Analysis by Distance Indices (SADIE) was used to identify significant aggregations and interpolated maps generated to characterize distribution patterns of adults within season and between yrs. Overall, the distribution of glassy-winged sharpshooters varied seasonally with individuals captured primarily in woodlands and fallow fields during early season mo. Later in the growing season and as population levels increased, sharpshooters were captured more commonly in crop habitat, including wheat and corn fields. By evaluating spatiotemporal distribution patterns, we identified likely sources of spring migration into cropping systems. Thus, pest management strategies for the glassy-winged sharpshooter should seek to limit early spring migration from non-crop habitat into crop fields.
