PBC Whitefly Taskforce


hedgesWhiteflies have become a major issue in South Florida with at least four species of particular concern: Ficus, Rugose Spiraling, Bondar’s Nesting and Silverleaf. Residents have noticed plant leaves yellowing, dropping, covered with white waxy material called flocculent, or covered with whitefly excrement called honeydew and its accompanying sooty mold. Plants, walkways, cars, outdoor furniture and even pools may become covered with the sticky material or flocculent. Whiteflies are among the many pests that are part of living in a subtropical climate. They can be managed with proper plant cultural practices; use of other beneficial insects, mites and fungi; and judicious application of the appropriate pesticides.

This webpage was developed to provide accurate, unbiased and research-based information to help residents, businesses and governments find the correct answers and to sort through the misinformation that can develop around major pest issues. 

whiteflyThe Palm Beach Whitefly Task Force was established to address these local needs.   This group is organized by University of Florida Extension and Research faculty in collaboration with local media, industry members, the Florida Department of Agriculture and Consumer Services, the United States Department of Agriculture (APHIS–PPQ), and local governments.

Short and long-term strategies are being developed and expanded by the task force to more effectively deal with whitefly challenges.  The group is producing additional research based informational and educational materials to help deal with the issues. Check this page periodically for updates.
