This data publication includes microsatellite markers allele calls for Harringtonia lauricola (previously Raffaelea lauricola) a fungal nutritional symbiont of its vector the redbay ambrosia beetle, Xyleborus glabratus Eichhoff, the cause of laurel wilt disease. Both are native to Asia but appeared in Georgia in the early 2000s. Laurel wilt has since spread to much of the southeastern United States killing >300 million host trees in the Lauraceae plant family and reacted as far north as Kentucky and west to Texas. Data, collected from 2009-2016, include a panel of 12 simple sequence repeat (SSR) markers identified 15 multilocus genotypes (MLGs) in a collection of 59 isolates from the USA (34 isolates), Myanmar (18), Taiwan (6) and Japan (1). The objectives of this project were to elucidate the genetic structure of populations of H. lauricola, to examine its reproductive strategy, and determine how often the pathogen had been introduced to the USA. For more information about this study and these data, see Dreaden et al. (2019).
