  1. Invasive Brown Marmorated Stink Bug (Halyomorpha halys) Prepared by Dr. Chris Maier, The Connecticut Agricultural Experiment Station

  2. Selected Headlines “Stink Bugs Taking Area Homes by Swarm” “Brown Marmorated Stink Bug Runs Amok” “Stink Bug Numbers Explode Along East Coast” “Move Over Bedbugs: Stink Bugs Have Landed” “Stink Bug Destroys Half of Pennsylvania’s Peach Crop” “Invasive Species Brown Marmormated Stink Bug Threatens U.S. Food Crops”

  3. Brown Marmorated Stink Bug Origin: Eastern Asia Initial Detection: Pennsylvania in 2001, but probably present since 1996 Distribution in U.S.: 33 states, including most eastern states Hosts: More than 70 plants in U.S., and 200- 300 worldwide

  4. Stink Bugs: Pentatomidae Five-segmented antennae Forewings are hemelytra, with basal half thickened and the apex membranous Piercing-sucking mouthparts When disturbed, release foul-smelling substance from glands on the thorax Of the 55 species in Connecticut, 16 are predators and 39 are herbivores

  5. Life Stages

  6. Development 2 3 4 5 ♂ ♀

  7. Biological Characteristics and Potential Problems • One generation per year • Feeding by adults concentrated in late May- • early June and in August-September • Highly mobile adults • Potentially a serious pest of fruit, legume, nut, • and vegetable crops • Nuisance pest in dwellings as adults seek • overwintering sites in September and October

  8. Aggregations in September-October

  9. Distribution in the United States

  10. Distribution in Connecticut Towns

  11. Damage

  12. Crops Damaged Apple Asian pear Grape Hazelnut Nectarine Peach Pear Pecan Plum Raspberry Cucumber Eggplant Field corn Green pepper Okra Pole bean Soybean String bean Sunflower Sweet corn Tomato

  13. Kinds of Fruit Damage Aborted young fruit Catfacing/deformation External feeding scars Internal brown coloration below feeding sites Potential disease transmission

  14. Apple Damage

  15. Peach Injury

  16. Corn Damage

  17. Bean Damage

  18. Tomato Injury

  19. Pepper Damage

  20. Soybean Injury

  21. Nut Damage

  22. Monitoring Methyl 2,4,6-decatrienoate

  23. Control Insecticidal control Initial lab tests suggest that certain pyrethroids and neonicotinoids may have the most promise Disruptive to natural enemies, undermine IPM programs Repeated use fosters outbreaks of secondary pests In field, bugs knocked down by pyrethroids sometimes recovered (add endosulfan?) Very hazardous to bees Biological control with parasitic wasps, 3 species from Asia(Trissolcus spp.)Impact native pentatomids? Cultural controlDiversionary or trap crop withhighly preferred host plantsDesign a system minimal impact onpollinators Kim A. Hoelmer, USDA, Newark

  25. Possible Insecticides for Stink Bugs • Bifenture, Brigade, Fanfare (best in lab tests, registered for pears) • Danitol (other stink bugs on label; <2 applications/year) • Taiga Z, Warrior II, λ-Cyhalothrin (good in lab tests) • Actara (good in lab tests, registered for stink bugs on peach) ___________________________________________________ • Aza-Direct, Azatin, and Neemix(frequent applications) • Avaunt (not registered for stink bugs) • Beleaf (not registered for stink bugs, but good on plant bugs) • Proaxis • Provado (suppression only) • Surround (frequent applications) • Thionex (mainly on stone fruits for catfacing insects)
