What it is:

-Very common leaf feeding pest on Honeylocust trees


Why:

-Causes disfigurement of new leaf and shoot growth, can contribute to tree stress

-Repeated annual infestations can cause accumulation of deadwood in tree (due to reduced

photosynthesis)

-Causes excess leaf litter

-Can vector diseases and viruses


How:

Options-

-Permethrin spray in early spring before tree leaf-out

-Imidacloprid soil treatment in fall for next spring*
