Extensive mortality of redbay has been observed in the coastal plain counties Georgia and southeastern South Carolina since 2003 northeastern Florida 2005. We show that is due to a vascular wilt disease caused by an undescribed Raffaelea sp. fungal symbiont Xyleborus glabratus, exotic ambrosia beetle. Trees affected exhibit symptoms include black discoloration sapwood. Redbay trees containerized seedlings died within 5 12 weeks after inoculation with When were challenged X. beetles tunneled...
This recovery plan is one of several disease-specific documents produced as part the National Plant Disease Recovery System (NPDRS) called for in Homeland Security Presidential Directive Number 9 (HSPD-9). The purpose NPDRS to insure that tools, infrastructure, communication networks, and capacity required mitigate impact high-consequence plant disease outbreaks are such a reasonable level crop production maintained. Each intended provide brief primer on disease, assess status critical...
Laurel wilt is a vascular disease of Lauraceous plants caused by fungus (Raffaelea spp.) that vectored recently introduced, nonnative ambrosia beetle (Xyleborus glabratus). The devastating to redbay (Persea borbonia) trees in forests, parks, and residential landscapes the southeastern United States, management strategies for reducing its impact are needed. In this study, systemic fungicide propiconazole completely inhibited mycelial growth Raffaelea spp. vitro at concentrations 0.1 parts per...
Research Highlights: Sentinel-2 Normalized Difference Vegetation Index (NDVI) products show greater potential to detect indications of disturbance by bark beetles in the southeastern US than Moderate Resolution Imaging Spectroradiometer (MODIS), as high spatiotemporal heterogeneity forest land prevents its deployment at current resolution. Background and Objectives: Remote sensing technologies have been an essential tool disturbances caused insect pests through spectral trait variation. In...
Silk bay (Persea humilis Nash) is a member of the Lauraceae precinctive to scrub forests central and southern Florida sister species primary laurel wilt host, redbay (P. borbonia (L.) Spreng), which generally not found in these ecosystems. In November 2011, observations silk mortality near Lake Placid Highlands County, FL, were reported Forest Service agents. A subsequent visit roadside homeowners' properties area revealed many dead dying silkbays with characteristic symptoms, including...
EENY-388, a 7-page illustrated fact sheet by Jeffrey M. Eickwort, Albert E. Mayfield III, and John L. Foltz, describes three species of pine bark beetles in the genus Ips -- sixspined ips, I. calligraphus (Germar); eastern fivespined grandicollis (Eichloff); small southern engraver, avulsus (Eichloff) which live predominantly inner stressed pines United States, where they breed feed on phloem tissue. Includes selected references. Published UF Department Entomology Nematology, September 2006....

 All pine species in Florida are susceptible to red heart disease. The disease can decrease timber value and weaken trees, making them threats people property. In forests, however, the same be beneficial cavity-nesting animals like red-cockaded woodpeckers. This 3-page fact sheet written by Yin-Tse Huang, Jeffrey Eickwort, Jiri Hulcr published UF/IFAS School of Forest Resources Conservation describes provides some tips manage it areas where could cause problems for...
The southern pine beetle (SPB), Dendroctonus frontalis Zimmermann, has been the most economically important forest insect in timber industry United States. From 1960 through 1990, bark caused economic losses estimated at $900 million (Price et al. 1992). 1998 to 2002, a four-year outbreak Appalachian Mountains affected more than 1 acres with an loss of $1 billion (Clarke and Nowak 2009). In 2001,17,599 were damaged by SPB Florida alone, causing $38 damages. While spectacular outbreaks have...
