Ash Plant Bug - Tropidosteptes amoenus Reuter   Whitney Cranshaw, Colorado State University, James Solomon, USDA Forest Service www.ipmimages.org www.ipmimages.org  HOSTS: Ash. DESCRIPTION:
Light
brown “true bug” about ¼ to ½ inch long . Nymphs are
oval, shiny yellowish or reddish brown and lack wings. LIFE
CYCLE:
Overwintering eggs are laid under loose bark. Nymphs hatch out in late
spring and feed on lower leaf surfaces. Most injury occurs in the
spring since the nymphs begin to mature by early summer. First
generation adults insert eggs into the midribs of leaves and a second
cycle of feeding occurs in late summer. Second generation adults
produce overwintering eggs. CONTROLS:Chemical: Use insecticidal soap if >40% of leaves are infested. Injury is mostly cosmetic only. |
