BROWN MARMORATED STINK BUG:ONE TOUGH NUT FOR GROWERS TO CRACK

摘要

IN THE CENTRAL Valley of California, we first located a large population of brown marmorated stink bug (BMSB) in Sacramento in 2013. Since then, it has been spread to 16 counties, and largely remains as a backyard nuisance and in several cities and towns. In 2017, we reported the infestation of brown marmorated stink bug in a commercial almond orchard near Modesto in Stanislaus County. Since then, this pest has been detected alive and in traps in several almond and peach orchards in the Northern SanJoaquin Valley, and has begun to cause economic damage to a few almond orchards in the area. Although the BMSB population in the commercial orchard is limited to a few counties to this date, when present, they are causing economic damage to crops — in some cases, very substantial damage.
