Tri-ology is a publication issued six times per year by the Florida Department of Agriculture and Consumer Services Division of Plant Industry (DPI). Each issue summarizes detections resulting from nursery plant inspections, routine and emergency program surveys, requests for identification of plants and pests from the public and samples that are occasionally received from other states or countries for identification or diagnosis.
The most recent bulletin, covering September–October 2015, can be viewed and downloaded here. Examples from the current circular include:
Bactrocera dorsalis, Oriental fruit fly. Based on the large number of flies detected in a concentrated area of the Redland Agricultural District in late August, a quarantine area regulating the movement of oriental fruit fly host plants was established on September 4, 2015. All entities within the quarantine production, sale or distribution of oriental fruit fly host material have been placed under a compliance agreement program requirements.
Pseudocercospora artanthes (leaf spot) was found infecting Piper auritum (Vera Cruz pepper) at the Jacksonville Zoo and Gardens in Duval County. This fungal pathogen flourishes when temperatures are moderate (~76 F) and humidity is high.
Bischofia javanica Blume (Javanese bishopwood) is an evergreen tree that can reach 18 meters in height in Florida, but up to 40 meters in natural areas of its native range. This species has escaped from cultivation in Central and South Florida to invade old fields and disturbed wet sites and is listed as a Category I invasive by Florida Exotic Pest Plant Council (FLEPPC). Bishopwood was introduced to Florida in the early 1900s. Almost four decades ago, it was included in a list of “pestiferous” ornamentals in South Florida and has continued to be a problem species, but one that is rarely sold now
Aphelenchoides besseyi Christie, 1942, the rice white-tip nematode, was detected in foliar tissues of the hybrid, annual ornamental, Zinnia elegans.
Tri-ology is produced by DPI’s Bureau of Entomology, Nematology and Plant Pathology, hence the name “Tri-ology.” The Botany Section is included in this bureau. Tri-ology has been published for 54 years. and recent volumes are available on-line, here.
