More Than a Nuisance, Now an Economic Stink in Crops

  • An invasive species originating in Asia
  • Damaging to fruit, vegetable and ornamental crops
  • Nuisance pest in structures such as homes and commercial buildings
  • Few natural predators in North America

The Brown Marmorated Stink Bug (BMSB) has now been detected in North America in at least 42 states and two Canadian Provinces. Levels of significance vary from detection to nuisance to severe economic impact, according to

First detected in Pennsylvania in 1998, BSMB quickly gained a foothold and spread. In agriculture, it is particularly devastating in the mid-Atlantic at present and is expected to expand and increase in economic significance to other states in coming years.

The U.S. Apple Association estimated that stink bugs caused $37 million in damage to apple growers in Maryland, Pennsylvania, Virginia and West Virginia in 2010.

BMSB attacks numerous field crops, but is particularly damaging to orchard crops where their piercing, sucking feeding activity damages fruit rendering it either unsalable or deeply discounted..
