Extent of BMSB Problem in Vegetables
BMSB feeds on a wide range of vegetables, including eggplant, lima beans, okra, pepper, snap beans, sweet corn, and tomatoes. Sweet corn appears to be a strongly preferred host crop. Okra may be an indicator for potential feeding damage to another important related crop, cotton. BMSB may carry plant pathogens that can damage vegetables. Also, BMSB may move from one host type to another. Researchers have found very little injury in cruciferous and cucurbit vegetables.
Researchers are studying what causes BMSB to switch hosts in landscapes with high infestations. They are studying the cumulative fruit damage over the crop cycle. Researchers are exploring whether traps may be used as monitoring tools in sweet corn and lima beans.
- Our team is monitoring over 7,000 acres of sweet corn fields and mapping effects.
- Our team has monitored BMSB on sweet corn, okra, peppers, tomatoes, snap beans, and eggplant in Delaware, Maryland, New Jersey, and Virginia.
Updates and Findings
- Vegetables may be at risk if isolated and not near a more attractive host for BMSB.
- BMSB preferred okra early in the growing season, but sweet corn was more generally preferred throughout the season.
In the mid-Atlantic, vegetable crops are attacked by several different stink bug species. The primary pest species include the brown marmorated stink bug, brown stink bug, green stink bug, and harlequin bug. Source: Virginia Cooperative Extension, November 2015.
