Insect Pest Survey Programs
Why survey?
Each summer the Oregon Department of Agriculture conducts surveys for insect pests not known to occur in Oregon. These pests such as gypsy moth , Asian gypsy moth, and Japanese beetle are serious pests in other parts of the country or abroad and could threaten Oregon´s agricultural and horticultural industries, urban and rural landscapes, forests, and recreational areas. Early detection of these pests allows the Department of Agriculture to be proactive in managing these pest problems.

What do the traps look like?

There are various trap types set by the Oregon Department of Agriculture. Several of the traps are made of heavy paper and are tent-shaped with sticky inner surfaces. These heavy paper traps are designed to catch moth pests and can be seen hanging from many different deciduous tree hosts. Another type of trap set in the state is the Japanese beetle trap. These traps are green or green and yellow and consist of a funnel and a catch can. These traps hang on a metal pole that is set into the ground near hosts such as turf, roses, or grapes.
Some ODA insect surveys for pests such as Asian longhorned beetle are visual since no traps exist to monitor them. Survey technicians visually inspect host trees for signs of damage.

How do the traps work?
Most of the traps used in our surveys are baited with a synthetic female sex lure called a pheromone. The Japanese beetle trap has floral food lure in addition to the pheromone lure. Traps are placed in areas where there are suitable food plants for the target insect. When the target insect also occurs in the area, adult males are attracted to the lure and are trapped.

Are the traps dangerous?
No. The traps are considered non-toxic, and do not contain any insecticides. However, it is best not to allow children or others to play with or disturb the trap or lures.

How can you help?
You can help in several ways to keep insect pests out of Oregon. First, report any suspect pest insects to the Oregon Department of Agriculture: 503-986-4636 or 1-800-525-0137. If possible, catch the suspect insect(s) and place it in a container for identification.
Second, your cooperation is greatly appreciated when you give us permission to place insect traps on your property. Third, be sure to observe quarantine regulations for insects such as gypsy moth by not moving infested materials into the state.
