Lygus lineolaris (Homoptera: Miridae)
Tarnished plant bug
Why: L. lineolaris came to our attention because it is considered as a pest of ornamentals in south-eastern USA.
Where:
North America: Canada, Mexico, USA (widespread, prefers warm, humid to dry climates in the South, Southeast and Southwest).
 |
On which plants: Polyphagous species (fruits, vegetables, ornamentals, field and forage crops, weeds). Glasshouse hosts include Aster, chrysanthemums, Dahlia, Impatiens and Tagetes.
Damage: By feeding, adults and nymphs cause yellowing, distortion of terminal growth and reduced plant growth. Flowers from damaged buds sometimes fail to develop on one side or the whole bud aborts.
Pathway: Glasshouse ornamental plants for planting (cut flowers?) from North America.
Possible risks: Polyphagous species which may attack many crops grown in Europe. Ornamentals under glass might be more at risk.
