Blackberry and Raspberry-Stink bug

Includes consperse stink bug (Euschistus conspersus)

Pest description and crop damage Large, bright-green bugs, shield-shaped and flattened. They have a foul odor and may contaminate berries at harvest. The machine harvester can shake insects from the plants, potentially contaminating berries going into the harvest trays.

Management-cultural controls

Correct adjustment of air-blast or vacuum-suction cleaner systems on mechanical harvesters can lessen insect contamination of machine-picked berries.

Management-chemical control: HOME USE

  • acetamiprid
  • azadirachtin-Some formulations are OMRI-listed for organic use.
  • bifenthrin
  • carbaryl
  • esfenvalerate
  • kaolin-Applied as a spray to leaves, stems and fruit it acts as a repellent to some insect pests. Some formulations are OMRI-listed for organic use.
  • neem oil-Some formulations are OMRI-listed for organic use.
  • permethrin-For use on raspberries only.
  • plant essential oils (cinnamon, clove, peppermint, rosemary, thyme)-Some formulations are OMRI-listed for organic use.
  • pyrethrins-Some formulations are OMRI-listed for organic use.
  • zeta-cypermethrin

Management-chemical control: COMMERCIAL USE

Products applied for leafroller control before harvest (such as: bifenthrin, esfenvalerate, fenpropathrin, malathion, and zeta-cypermethrin) may provide some control of stink bugs. Insecticides registered specifically for stink bugs include:

  • fenthropathrin (Danitol) at 0.2 to 0.3 lb ai/A. PHI 3 days. Highly toxic to bees-do not apply during bloom. Restricted use pesticide.
  • pyrethrins (PyGanic and others)-Consult label for rate. PHI 0 days. Some formulations OMRI-listed for organic use.
  • thiamethoxam (Actara) at 0.047 lb ai/A. PHI 3 days. Highly toxic to bees-do not apply during bloom.
