The brown marmorated stink bug feeds on a wide range of fruits, vegetables, and other host plants beginning in late May/early June including apples (especially Fuji), cherry, raspberries, pears, peaches, figs, mulberries, citrus, persimmon, jujube, and soybeans. It has been implicated as a vector of witches' broom (an MLO) in Paulownia.


Commodities Affected:
Field Crops, Forestry and Natural Areas, Fruits and Vegetables, Nursery, Ornamentals, and Turf



The brown marmorated stink bug has been known to cause severe crop damage in Asia. It attacks numerous fruit trees (among other crops), and can also damage fruit directly, causing (for example) "cat-facing" on apples, which renders them unmarketable. In addition, the brown marmorated stink bug has the potential to act as a disease vecto. It is a significant nuisance pest by clustering in structures in the fall.



The brown marmorated stink bug is known to occur in many eastern US states including Indiana.
