  1. Brown Marmorated Stink Bug (Halyomorphahalys) D. Duerr, USDA Forest Service, Bugwood.org

  2. Outline • History/Distribution • Identification • Life History • Why is it Important? • Control

  3. Where in the U.S. are BMSB Most Common? • Eastern U.S. • Upper Midwestern • Southern U.S. • Pacific Northwest 0 of 30

  4. History/Distribution • Originally from China • First found in the U.S. in PA in 2001 (1st specimens were actually collected in 1996) • Most abundant in mid Atlantic states David R. Lance

  5. History/Distribution • BMSB numbers particularly high in eastern U.S. in 2010 • Caused economic loss in some crops

  6. History/Distribution • In 2011, BMSB were not consistently high as in previous year • Not in high numbers in MN (yet) • How long before abundance in MN is like eastern U.S.??

  7. History/Distribution • First found in St. Paul (Ramsey Co.) in Nov. 2010 in MDA building • Possibly associated with package received from eastern U.S.

  8. Distribution in MN: 1- Ramsey Co. 1- Washington Co. 2- Anoka Co. 1- Winona Co. 1- Hennepin Co. 1- Chisago Co. 1- Carver Co. As of Feb. 2012 X X All were found in homes/buildings X X X X

  9. Identification • Stink bugs are shield-shaped • Possess large triangular plate on back • Well developed scent glands

  10. Identification Possesses piercing-sucking mouthparts

  11. Identification of BMSB • About ½ inch long • Mottled brownish and grayish (marmorated = marbled) • Has banded antennae • Banded abdomen • Veins highlighted in black Whitney Cranshaw

  12. Identification of BMSB • Metallic greenish gold ‘flecks’ on underside of BMSB

  13. Identification • Young nymphs yellowish brown, mottled with black and red David R. Lance

  14. Identification • Older nymphs darker, with light bands on dark legs and antennae Susan Ellis

  15. Don’t Confuse BMSB With… Other true bugs Western conifer seed bug Boxelder bug

  16. Don’t Confuse BMSB With… Native stink bugs Native stink bugs

  17. Comparison of insects that might be confused with BMSB Brown marmorated stink bugs Native stink bugs Masked hunter BEB WCSB Squash bug

  18. Which is BMSB? • Insect A • Insect B • Insect C A B C 0 of 30

  19. Life History • Overwinter as adults • Emerge about May • Between June and August, lays about 28 eggs at a time on undersides of leaves • Can lay eggs several times David R. Lance

  20. Life History • Nymphs feed throughout summer • Mature into adults by fall • One generation per year Gary Bernon

  21. On about how many different kinds of plants does BMSB feed? • 10 • 20 • 200 • 2000

  22. Why Is It a Pest? • Feeds on 200 + plants • Ornamental and nursery plants, e.g. crabapples, maples, rose, Norway maple, white ash, viburnum, catalpa, hackberry, dogwood, willow, lilac Gary Bernon Gary Bernon

  23. Why Is It a Pest? • Nymphs feed shallowly • Adults feed more deeply and cause more severe damage • On leaves generally appears as small stippled areas and/or necrotic areas

  24. Why Is It a Pest? • Can feed directly on fruit and vegetables • Can cause water-soaked lesions, pitting, dimples, catfacing, depressed areas • On vegetables, e.g. beans, can cause warty growths USDA

  25. Why Is It a Pest? • Crop pest: - Fruit, e.g. apple, peach, grape, raspberry - Ag crops, e.g. soybeans, corn, bean, peas, tomato, pepper Gary Bernon

  26. Why Is It a Pest? • Nuisance invader in structures in fall, like boxelder bugs and multicolored Asian lady beetles • Has well developed scent glands!! Susan Ellis

  27. Control • Use of insecticides, although control challenging, not always effective • This is not long-term solution • Research into possible biocontrol agent – tiny parasitic wasp that attacks eggs Susan Ellis
