Summer 2020

Brown marmorated stink bug (Halyomorpha halys, Stal) (BMSB) is an invasive species which causes economically significant damage to tree fruit, vegetable, ornamental and field crops. This pest was first discovered in the US in eastern Pennsylvania in the late 1990s but has subsequently spread to over 40 states including many where fruit production is widespread (citation for BMSB first detection (Hoebeke and Carter 2003)“StopBMSB.org” 2020). Initially, stink bugs were primarily a nuisance pest for homeowners who ombatted populations invading their homes each fall (Nielsen and Hamilton 2009). However, damage from
BMSB feeding was soon observed in commercial orchards and by the late 2000s, this pest was a growing concern for fruit growers in the Mid-Atlantic states. Currently, BMSB is considered a serious pest of tree fruit within the US, causing major damage to apples, pears and especially peaches (Holtz and Kamminga 2010).
