Symptoms of ALB Infestation
• Large emergence holes
on branches or the
stem (>3/8” diam).
• Sawdust accumulates
at branch crotches or
tree base.
• Flagging & dieback
in the canopy.
Repeated ALB Attacks

Hosts of ALB
Prefers:
• Maples (Acer species).
Will also infest:
• Horsechestnut (Aesculus hippocastanum),
• Elms (Ulmus spp.),
• Birches (Betula spp.),
• Willows (Salix spp.),
• Poplars (Populus spp.),
• and many others.
Potential for Widespread Damage
to Native Trees is High
Currently, ALB is known to be
established in
New York City (1996)
& Chicago (1998)

What is being done about ALB
in New York & Chicago?
Goal  ERADICATION
• Removal & disposal of infested trees
• Replanting with non-host species

Replanting Strategies
• Resistant
species
• Diverse plantings
What Should You Do if You
Find A Suspect Beetle?
• Capture at least 1 adult beetle.
• Preserve in 70% rubbing alcohol.
• Take beetle to professional entomologist
for identification.
Where Can You Take Beetles for
Identification?
• County Extension Office
• State Department of Agriculture
• State Department of Natural Resources
• University Plant Pest Diagnostic Clinic
• USDA Forest Service Office
Remember, Some Native
Beetles are Similar to ALB
• Many native woodboring beetles are black
& white with long
antennae
• An entomologist can
assist with identification
of suspect beetles.
