Since its initial discovery in Allentown, PA, USA, the brown marmorated stink bug (BMSB), Halyomorpha halys, has now officially been detected in 38 states and the District of Columbia in the USA. This Asian species (see map) quickly became a major nuisance pest in the mid-Atlantic USA region due to its overwintering behavior of entering structures. BMSB has an extremely wide host range in both its native home and invaded countries where it feeds on numerous tree fruits, vegetables, field crops, ornamental plants, and native vegetation. In 2010, populations exploded causing severe crop losses to apples, peaches, sweet corn, peppers, tomatoes, and row crops such as field corn and soybeans in several mid-Atlantic states. Damaging populations were detected in vineyards, small fruit, and ornamentals. Researchers are collaborating to develop management solutions that will complement current integrated pest management programs.
Australia and New Zealand are requiring a certificate of fumigation on all inbound non-commodity products like cars, agricultural parts, and other containerized and noncontainerized items that could contain overwintering stink bugs. At this writing, there are about 1000 containers being fumigated for the BMSB each week in ports located on the east coast of the United States. Treatment: Sulfuryl flouride and methyl bromide Q-gas are approved by the Australian government to treat for BMSG on imported items. In New Zealand, Methyl bromide is the only product allowed at this time for BMSB.
