Hosts

  • Field-grown hemp
  • Grasses
  • Alfalfa
  • Sorghum
  • Clover
  • Solanaceae crops
  • Peaches
  • Corn
  • Many more groups of plants

Description

Adults are shield-shaped, and the wings are thick and leathery on the front half and membranous in the rear portion. Coloration typically varies from green to brown, but other colors may occur. Nymphs are smaller than adults and do not have fully-developed wings (only wing pads). Their coloration is usually different from the adult stage, and changes as nymphs mature. Eggs are barrel-shaped and laid in clusters of 10 to 30 on host leaves. 

Life Cycle

Egg | Nymph | Adult

  • 2-3 overlapping generations per year.
  • Overwinter as adults under leaves, plant debris, weedy areas, and other protected sites such as buildings or structures, wood piles, or dead trees.
  • Eggs typically laid on host plant leaves.

Damaging Lifestage(s): Nymph, Adult

Damage Symptoms

Nymphs and adults feed on cells with piercing-sucking mouthparts. To date, symptoms have not been documented on hemp, including any flower or seed damage. 

Time for Concern

Throughout the growing season.

When and Where to Scout

  • Egg clusters and stink bugs can be found on hemp plants starting in midsummer through harvest.
  • Larger populations may occur along field edges.

Threat Level

Low; stink bugs have not caused significant damage to hemp

Occurrence in Utah

All stink bug species listed above occur in Utah and many have been found on hemp, but not causing economic damage or visible symptoms.

Management

  • Attract and conserve natural enemies.
