Minnesota First Detectors Bob, I see conflicting years for the first find. What would be best to go with?3Eastern U.S.Upper MidwesternSouthern U.S.Pacific NorthwestNot sureWhere in the U.S. are BMSB most common?

USDA-NIFA SCRI from www. stopbmsb.orgMinnesota First Detectors History/DistributionFirst collected in PA in mid 1990s (not confirmed until 2001)

Minnesota First Detectors Bob, I see conflicting years for the first find. What would be best to go with?6History/Distribution BMSB numbers particularly high in eastern U.S. in 2010 (due to weather?)Caused economic loss in some crops

Minnesota First Detectors Question will be how long before numbers in MN get like eastern U.S. in 20107History/Distribution In 2011-2012, BMSB (i.e. crop damage) were not as consistently high as in 2010Not in high numbers in MN (yet!)

Minnesota First Detectors About 7-8 years on average once it is found before you see significant numbers.8History/DistributionFirst found in St. Paul (Ramsey Co.) in Nov. 2010 in MDA buildingPossibly associated with package received from eastern U.S.

Minnesota First Detectors 9All were found in homes/buildingsDistribution in MN:1- Ramsey Co.1- Washington Co.3- Anoka Co.1- Winona Co. 4- Hennepin Co.1- Chisago Co.1- Carver Co.1- Dakota Co.

As of December, 2012

Minnesota First Detectors First found in MN in Nov and Dec of 201010

Which is BMSB?

ABCInsect AInsect BInsect C0 of 30Minnesota First Detectors A = BMSBB = Leaf-footed bug (this image was actually sent by a MG wondering if this could be BMSB)C = native stink bug20Life HistoryOverwinter as adultsEmerge about MayBetween June and August, lays about 28 eggs at a time on undersides of leavesCan lay eggs several timesDavid R. Lance

Minnesota First Detectors Can lay eggs multiple times as many as 200+ total eggs in an individual females lifetime21Life HistoryNymphs feed throughout summerMature into adults by fallOne generation per yearCan see adults through most of year

Minnesota First Detectors Why Is It a Pest?Feeds on 300 + plantsNymphs have shorter mouthparts, feed more shallowlyAdults feed more deeply and cause more severe damage

Stephen Ausmus

Minnesota First Detectors Why Is It a Pest?Ornamental and nursery plants, e.g. crabapples, maples, rose, Norway maple, white ash, viburnum, catalpa, hackberry, dogwood, willow, lilac On leaves generally appears as small stippled areas and/or necrotic areas

Gary Bernon

Minnesota First Detectors 25Why Is It a Pest?Crop pest: - Fruits, e.g. apple, blackberry, peach, grape, raspberry- Vegetables, e.g. sweet corn, bean, peas, tomato, pepper- Field crops, e.g. soybeans, field corn

Gary Bernon

Minnesota First Detectors Top = tomatoBottom = peach26Why Is It a Pest?Can feed directly on fruits and vegetablesInjury through removal of plants cells and injecting salivaCan cause water-soaked lesions, pitting, dimples, catfacing, depressed areas, warty growths

USDAMinnesota First Detectors Catfacing = misshappen fruit with scars and holes on the blossom end.27Why Is It a Pest?Nuisance invader in structures in fall, like boxelder bugs and multicolored Asian lady beetlesHas well developed scent glands!!
