Light brown apple moth
Light brown apple moth (LBAM) detections
The Oregon Department of Agriculture (ODA) caught 1 light brown apple moth in 2010, 2 in 2015, and 3 in 2016. All moths were caught within a one square mile area south of Independence in Polk County. Catching moths in 2015 and then again in 2016 in the same general area indicates the presence of a breeding population of LBAM.
2017 Proposed LBAM eradication project south of Independence, Polk County
The proposed eradication program includes:
- Adult LBAM treatments: Two applications of SPLAT, a mating disruption pheromone, applied by airplane
- Larval LBAM treatments: Three applications of Bacillus thuriengensis kurstaki (Btk), a biological pesticide, applied by airplane
- Delimitation traps placed in the vicinity of the trap catches and detection traps placed statewide.
The treatments are tentatively scheduled to begin June 21, 2017.

2017 Japanese beetle detections
The Oregon Department of Agriculture (ODA) has trapped more than 13,000 adult Japanese beetles as of 8/4/2017:
- Most of the beetles trapped were within the Cedar Mill and Bethany treatment area. Roughly 2% of these beetles were caught just outside of the treatment area, some next to large parking lots and major thoroughfares. The beetles’ high population and mobility (hitch hiking on vehicles and or the movement of landscaping yard debris) from within the area are factors in this spread.
- Several beetles have been trapped inside and near the Portland Airport and Swan Island.
Spring 2017 Japanese beetle eradication project in Cedar Mill and Bethany
The Acelepryn® G treatment for Japanese beetle has been completed for the season. However, Japanese beetle traps will be used to monitor the beetles until the end of the season (October) in the infested area.

The Oregon Department of Agriculture, in conjunction with USDA and other federal and state agencies, conducted an eradication program in the North and Northwest Portland area in 2016. Approximately 7,000 acres were treated in April and May with an aerial application of a biological pesticide Bacillus thuringiensis kurstaki to eradicate the Asian and European gypsy moth infestation. To view the area where the treatment took place please see the map link below.
ODA has completed the trapping program for the 2016 season. We did not detect any gypsy moths in the Portland area, indicating the treatment was a success. However, we caught six gypsy moths in other parts of the state in 2016:
- Vida, Lane County, 2 gypsy moths
- Grants Pass, Josephine County, 4 gypsy moths
Detection traps will be placed throughout the state starting this spring. No eradication is proposed.

Oregon participates in a federal program to monitor, and
suppress when necessary, grasshoppers and Mormon crickets. Even though not all
grasshopper species are pests, outbreaks can vary in their magnitude and
geographic expanse. Early intervention can dampen the severity of an outbreak
Grasshopper survey report
The 2015 Oregon grasshopper survey season showed a continuing increase in the grasshopper population which had been declined through 2013 from a high in 2011. An estimated 2.4 million acres across eastern Oregon were found to be economically infested. ODA and USDA-APHIS did not participate in any control efforts during 2015, though from various informal reports we believe there were several programs for treating privately held land.
