There is less information on parasitoids of brown marmorated stink bug adults and nymphs, but so far only tachinid flies (some of which are known stink bug adult parasitoids) have been recorded to attack and emerge from brown marmorated stink bug, but instances are relatively rare.
Most of the management recommendations on tree fruits originated from work done in the eastern US, where brown marmorated stink bug has been established longer. While homeowners in Washington have noted damage to backyard fruits, vegetables, and ornamentals, the only damage to commercial orchards has been to farms in the greater Vancouver, WA area. Adult brown marmorated stink bug have been detected in vineyards in the Walla Walla area, but no damage has been reported. At this point, commercial growers in eastern Washington are advised to be vigilant for brown marmorated stink bug, but not to apply prophylactic sprays.
In the eastern US, brown marmorated stink bug is notorious for both causing high levels of crop damage in certain years, and disrupting ongoing IPM programs. The influx of adults from May through September has provoked a cover spray program to prevent damage, resulting in outbreaks of secondary pests (Leskey et al., 2012). While severe crop losses have been reported since 2010, the insect pressure is not uniformly high in all areas or years. Brown marmorated stink bug is a landscape-level pest, moving from crop to crop to fulfill its nutritional needs. It is also considered a border pest as it invades orchard edges from nearby crops and wooded areas. Several current management strategies utilize this behavior by focusing efforts on the crop perimeter.
The potential for disruption of Washington’s IPM programs in pome fruit is severe if brown marmorated stink bug establishes at levels similar to the mid-Atlantic states. The majority of the insecticides recommended for control of brown marmorated stink bug are pyrethroids, although a few other groups (neonicotinyls and carbamates) also have active ingredients that are effective (Bergh et al., 2016). Tactics being investigated to reduce the non-target impact of insecticides include border applications to reduce total amounts of pesticides applied (Blaauw et al., 2015), attract-and-kill strategies (Morrison et al., 2016), and exclusion using net barriers. (Marshall and Beers, 2016). Establishing biological control (such as the samurai wasp) in urban areas may prevent build-up and spread to agricultural areas.

Use pesticides with care. Apply them only to plants, animals, or sites listed on the labels. When mixing and applying pesticides, follow all label precautions to protect yourself and others around you. It is a violation of the law to disregard label directions. If pesticides are spilled on skin or clothing, remove clothing and wash skin thoroughly. Store pesticides in their original containers and keep them out of the reach of children, pets, and livestock.
YOU ARE REQUIRED BY LAW TO FOLLOW THE LABEL. It is a legal document. Always read the label before using any pesticide. You, the grower, are responsible for safe pesticide use.
