Honeylocust Plant Bug
- adults: ~ 3/16 inch; pale green; highly mobile
- nymphs: smaller than adults; do not have wings, and have an orange spot on the back
- eggs: oblong and white in color
Host Plants, Diet & Damage
- feed on sap of honeylocust leaves and buds with straw-like mouthparts
- white stippling on top of leaves; wilting, chlorotic, dwarfing, curling, bent and drying leaves
- dead leaf tissue will fall out of leaves when expanded causing irregular holes in leaves
- heavy damage can kill small branches and inhibit leaf development
- most damage occurs on young foliage in late-May and June
Biology, Life Cycle & Damaging Life Stage
- overwinter as eggs inserted into bark of twigs and branches
- egg hatch begins in May at the time of vegetative budbreak
- mate in late-May or June and lay overwintering eggs
- nymphs and adults disappear in July
- one generation per year
- nymphs and adults are the damaging stages
- Manage trees to improve or maintain health.
- Damage is mostly aesthetic, especially on larger trees.
- Plant resistant cultivars.
- Young or nursery trees may require control.
- Begin monitoring prior to budbreak.
- Apply an insecticide (carbamate; pyrethroid; horticultural oils; insecticidal soap) just after budbreak.
