Interpretive Summary: The invasive brown marmorated stink bug (BMSB) has expanded into the Piedmont and Coastal Plains Regions of Georgia and Alabama. The diversity of natural enemies attacking this pest is unknown in these states. A team of scientists from ARS, the University of Georgia, Clemson University, and Auburn University conducted a study to examine parasitism of BMSB egg masses in orchards, row crops, and vegetables. They discovered a new parasitic wasp, Trissolcus basalis, emerging from frozen BMSB egg masses in the United States. Further studies will be conducted assess the impact of this parasitic waps species on BMSB in crops and surrounding habitats.

Technical Abstract: The invasive brown marmorated stink bug (BMSB) has expanded into the Piedmont and Coastal Plains Regions of Georgia and Alabama. Because the diversity of natural enemies attacking this pest is unknown in these states, a team of biological control research scientists from ARS, The University of Georgia, Clemson University, and Auburn University deployed BMSB egg masses as sentinels in orchards, row crops, and vegetables. The egg parasitoid, Trissolcus basalis, emerged from fresh BMSB egg masses in tomato in Tuscaloosa, AL, cotton in Shorter, AL, and soybean in Auburn, AL. This is the first record of this parasitoid species attacking BMSB eggs in the United States. Further studies will be conducted to assess the impact of this parasitoid species on BMSB eggs in the southeastern United States.
