Entomology Circulars



The Entomology Circular series was established in the early 1960s to be an educational outlet for new agricultural pests, often of regulatory concern. They are primarily created by staff members to discuss newly established pests or pests that would pose threats to Florida’s plant life if established. These Circulars were short reports (often only 2 page) that were printed for distribution to stakeholders and the public. After the original release, the paper copies were used as educational fliers for many years. While some data are out of date, they are historically significant and much of the biological information contained in them are still scientifically valid. With the development of the internet, many were updated and re-released through the University of Florida’s Featured Creatures series. As the internet and digital technology created new ways to disseminate information more rapidly, the Circular series’ original purpose of a quick information release was taken over with DPI’s Pest Alert series that is posted on the DPI’s webpage. However, Pest Alerts are considered short, temporary multi-media postings to be discarded after a period of time. The Circular series continues to function as a more informative and permanent publication record on various pests or arthropods of concern to Florida.
