SpreadNotesScore
Spread RateEgg masses are laid on almost any smooth surface and are easily transported on nursery stock, shipping pallets, vehicles, and other objects. Adults capable of flight but general disperse by walking. 5
Spread AmountApples, birch, cherry, grapes, lilac, maple, poplar, stone fruits, and tree of heaven are among >70 species of principally woody hosts. 5
DamageNotesScore
EcologicalIncreased insecticide usage would result to manage this pest if it established - this could threaten environmental quality. Infestations can weaken native plants and eventually kill them. 2
AgriculturalMay lower crop yields and increase production costs in economically important crops such as grape, stone fruit, and nursery stock.5
InfrastructureWill lay Oothecae on any smooth surface. 1
CulturalAttacks many important ornamental plants. Large aggregations may create a nuisance in urban areas. Produces significant honey dew. 3
HealthConsidered poisonous to humans if consumed. 1

Ability to Respond

Ease of ResponseNotesScore
DetectionEgg masses can be on shipped on almost any smooth surface coming from infested areas. Egg masses also known to be laid on cars and air transport. 2
ControlChemical control reduces adult populations, but currently ineffective for long-term control, and lanternflies can quickly repopulate after sprays. Future potential for biocontrol, attractants, and repellants. 2
