3

What effects can Spotted Lanternflies have when feeding on TREE species? *

Reduction of Carbon Assimilation

Reduction of Transpiration

Reduction of total nonstructural carbohydrates

Reduction in tree diameter

Spotted Lanternfly feeding will reduce carbon assimilation and transpiration, leading to lower total nonstructural carbohydrates and thus a reduction in tree diameter.

4

What effects can Spotted Lanternflies have when feeding on GRAPEVINES? *

Reduction of Carbon Assimilation

Reduction of Transpiration

Reduction of Stomatal Conductance

Reduction of leaf blade and root Nitrogen

Reduction of Brix levels

Spotted Lanternfly feeding will directly lead to lower carbon assimilation, transpiration, and stomatal conductance, which will ultimately lead to a reduction in Brix levels
