http://www.nurserymanagementonline.com/nursery-0611-brown-marmorated-stink-bug.aspxI just came across this article, and for folks inundated with this type of stink bug, might find it interesting. I didn't see follow-ups on the parasitic wasps yet:
Research is continually going on for this pest. And research continues to show that biological control is going to be the long-term strategy to control this pest. So far, U.S. native beneficials have not significantly controlled BMSB populations.
USDA researchers have identified four parasitic wasps in the genus Trissolcus from China that lay their eggs in BMSB eggs. During the next two years, these wasps will be evaluated for their effectiveness in quarantine facilities in Delaware.
Until evaluations on those parasitic wasps are complete, insecticidal applications are a grower’s only option. And these bugs can be hard to kill. Many of the products that provide control can be highly toxic to beneficial insects, interrupting ongoing pest management programs.
