In some US cities, there have been successful eradication programs for:
Both EAB and ALB
Neither EAB nor ALB
Which of the following is NOT a typical sign/symptom of ALB?

Which of the following is a characteristic of ash trees?
Leaves have 9 or more leaflets
Leaves and branches are opposite
Seeds are winged (samaras) and hang in pairs
Which of the following is NOT necessary to include in your EAB/ALB report?

Detailed description of your observations (including the specific signs and symptoms that you observed)
The name of the property owner
The name of the species that you are reporting
Which is an example of an invasive forest pathogen currently in Oregon?

Both of the above
None of the above
What is the main reason that it is difficult to control EAB?
The adult insects can fly very long distances
Symptoms of early infestation can be very hard to detect
No animals eat EAB because they are toxic
The insects live a long time

1/8 inch (3 mm)
1/4 inch (6 mm)
1/2 inch (10-13 mm)
3/4 inch (2 cm)
During which seasons are you most likely to see an adult ALB in Oregon?
late-spring to mid-fall
late-summer to mid-winter
late-winter to mid-summer
In which of the following scenarios would you feel it is NOT appropriate to report EAB or ALB?
You collect an insect specimen that looks like ALB. You compare this specimen to the look-alikes in Oregon. It does not appear to be any of the look-alikes.
You are driving in the country and notice a stand of unhealthy Oregon ash. You do not stop but you make a mental note of where the stand is located so you can report it later.
Using your binoculars, you notice what looks like D-shaped exit holes on the upper branches of an unhealthy ash tree in the woods behind your house. You also notice epicormic shoots stemming from the lower trunk. You collect a branch from the tree and confirm that it is an ash.
You notice a large amount of frass on the branches of a horsechestnut outside of your local community center. Upon closer inspection, you find round exit holes that are slightly smaller than a dime.
Which of the following is NOT a typical sign/symptom of EAB?
Woodpecker damage (stripping away the bark of the tree)
D-shaped exit holes that are 1/8-inch in diameter
Epicormic branches (shoots coming from the trunk of the tree)
Sap oozing from the trunk
Which insect only attacks large trees (greater than 12 inches diameter)?
Which picture shows an adult EAB?
If you think you see signs or symptoms of an EAB or ALB infestation, where should you report?
Call your local newspaper
Go to OregonInvasivesHotline.org
Do not report because it is likely to be a false alarm
