“…Previous studies examining the epidemiology of BSRD have focused on trapping and identifying the insects that spread the fungus that causes the disease (Harrington et al, 1985;Witcosky and Hansen, 1985). However, population genetics and genomics have become valuable tools to investigate the epidemiology and dispersal dynamics of both native and introduced plant pathogens (Linde et al, 2002(Linde et al, , 2009Rivas et al, 2004;Banke and McDonald, 2005;Goss et al, 2009;Rieux et al, 2011;Garbelotto et al, 2013;Barnes et al, 2014;Brar et al, 2015Brar et al, , 2018Grünwald et al, 2016;Bennett et al, 2019;Tabima et al, 2020Tabima et al, , 2021. Information about population structure and genetic diversity is essential for understanding how factors such as landscape topology or forest management practices influence the epidemiology and evolutionary biology of pathogens and for developing effective strategies for managing plant diseases (Linde et al, 2002Banke and McDonald, 2005;Heinzelmann et al, 2012;McDonald and Mundt, 2016).…”
