The Asian longhorned beetle in South Carolina: A status update and summary of ongoing research

After the Asian longhorned beetle (Anoplophora glabripennis, ALB) was found in South Carolina in May 2020, research quickly ensued alongside the USDA-APHIS ALB Cooperative Eradication Program. All data about this invasive forest pest's biology, behavior, and phenology in North America have been gathered from populations in very different climates compared to South Carolina’s subtropical climate. The abrupt translocation of ALB over 500 miles after a decade of successful management in Ohio calls for inventive research in order to begin characterizing the spread patterns. However, initial dendrochronology findings estimate the SC population to have been active for the past 7 years and genetic analyses show the SC population matches the genetics of the OH population. This talk will provide an update on the expansion of the quarantined area, management efforts, and introduce ongoing research projects. Clemson researchers have set out to characterize phenology (Schmitt) as well as the pace and patterns by which ALB spread: vertically within individual tree canopies and within a stand (Bean). NCSU researchers are developing and evaluating new eradication strategies to utilize swampy conditions as an advantage instead of hindrance to management (Ratcliff). While all current data and results are preliminary, many lessons have been learned thus far.
