X. bispinatus has been found to acquire the laurel wilt pathogen Raffaelea lauricola (T. C. Harr., Fraedrich & Aghayeva) when breeding in a host affected by the pathogen. Its role as a potential vector of R. lauricola is under investigation. The main objective of this study was to evaluate three artificial media, containing sawdust of avocado (Persea americana Mill.) and silkbay (Persea humilis Nash.), for rearing X. bispinatus under laboratory conditions. In addition, the media were inoculated with R. lauricola to evaluate its effect on the biology of X. bispinatus. There was a significant interaction between sawdust species and R.

Aghayeva3 *[email protected] 1Department of Plant Pathology, Iowa State University 351 Bessey Hall, Ames, IA 50011, USA 2Southern Research Station, USDA Forest Service Athens, GA 30602, USA 3Azerbaijan National Academy of Sciences Patamdar 40, Baku AZ1073, Azerbaijan Abstract — An undescribed species of Raffaelea earlier was shown to be the cause of a vascular wilt disease known as laurel wilt, a severe disease on redbay (Persea borbonia) and other members of the Lauraceae in the Atlantic coastal plains of the southeastern USA. The pathogen is likely native to Asia and probably was introduced to the USA in the mycangia of the exotic redbay ambrosia beetle, Xyleborus glabratus. Analyses of rDNA sequences indicate that the pathogen is most closely related to other ambrosia beetle symbionts in the monophyletic genus Raffaelea in the Ophiostomatales. The asexual genus Raffaelea includes Ophiostoma-like symbionts of xylem-feeding ambrosia beetles, and the laurel wilt pathogen is named R. lauricola sp. nov. Key words — Ambrosiella, Coleoptera, Scolytidae Introduction A new vascular wilt pathogen has caused substantial mortality of redbay [Persea borbonia (L.) Spreng.] and other members of the Lauraceae in the coastal plains of South Carolina, Georgia, and northeastern Florida since 2003 (Fraedrich et al. 2008). The fungus apparently was introduced to the Savannah, Georgia, area on solid wood packing material along with the exotic redbay ambrosia beetle, Xyleborus glabratus Eichhoff (Coleoptera: Curculionidae: Scolytinae), a native of southern Asia (Fraedrich et al.

The purpose of the NPDRS is to insure that the tools, infrastructure, communication networks, and capacity required to mitigate the impact of high consequence plant disease outbreaks such that a reasonable level of crop production is maintained. Each disease-specific plan is intended to provide a brief primer on the disease, assess the status of critical recovery components, and identify disease management research, extension, and education needs. These documents are not intended to be stand-alone documents that address all of the many and varied aspects of plant disease outbreak and all of the decisions that must be made and actions taken to achieve effective response and recovery. They are, however, documents that will help USDA guide further efforts directed toward plant disease recovery.

Shearman May 2016 Accepted by: Dr. G. Geoff Wang, Committee Chair Dr. Saara J. DeWalt Dr. Donald L. Hagan Dr. Julia L. Kerrigan Dr. William C. Bridges ABSTRACT Laurel Wilt Disease (LWD) has caused severe mortality in native Persea species of the southeastern United States since it was first detected in 2003. This study was designed to document the range-wide population impacts to LWD, as well as the patterns of mortality and regeneration in Persea ecosystems. I used Forest Inventory and Analysis (FIA) data from the U.S. Forest Service to estimate Persea borbonia (red bay) populations from 2003 to 2011 to see if any decline could be observed since the introduction of LWD causal agents.

DED and its vector beetles are widely present in most of the countries in the Northern Hemisphere, but they are not known to be present in Finland. DED is a major risk to plant health in Finland. DED and its vectors are moderately likely to enter Finland by natural spread aided by hitchhiking, because they are present in areas close to Finland. Entry via other pathways is much less likely, mainly due to the low volume of trade of untreated wood and plants for planting. DED and its vectors could likely establish in the southern parts of the country, since they currently occur in similar climatic conditions in other countries.
