Oregon Department of Agriculture is beginning its second year of the Japanese beetle eradication program. We invite you to come to a public open house to have all of your questions answered about the project. Two open houses are being offered: 1) Tuesday evening on February 6th from 5:30 pm–7:00 pm at Sunset High School Link to map: 13840 NW Cornell Rd, Portland, OR 97229 2) Tuesday morning on February 13th from 9:30 am–12:30 pm at the Leedy Grange Link to map: 835 NW Saltzman Rd, Portland, OR 97229 Representatives from Oregon Department of Agriculture will be there alongside partner agencies.

After treating the areas of Cedar Mill and Bonny Slope in Washington County this past spring, Oregon Department of Agriculture makes plans for Japanese beetle battle part 2. A total of just over 23,000 destructive Japanese beetles were caught in Washington County this year. “The threat to Oregon is more imminent now because of the numbers of beetles we are seeing and the fact that we have seen damage to plants within the epicenter of the insect’s population, so it’s not hypothetical, it’s for real,” says ODA’s Burfitt, a veteran of successful Japanese beetle eradication projects in Utah. “However, I’m still optimistic about eradicating our current infestations. As long as the community continues to support the 5-year project, I know we can get this done.” Find out more about the project: Oregon Department of Agriculture will be working with partners and the community throughout the winter and spring to make plans for year two of the proposed eradication project.

We recently made changes to www.japanesebeetlepdx.info website in order streamline our message. If you are looking for resources that were previously available on this website, check out the Oregon Department of Agriculture’s Insect Pest Prevention and Management webpage. We apologize for any inconvenience. Contact web administrators, info@samarapdx.com if you have any questions. PLEASE NOTE: THIS POST IS AN ARCHIVE FROM 2017.

View all current catches on the interactive map, here: As far as Japanese beetle habits go, the beetles are at the tail end of peak flight—which means there are many beetles flying—and it is important to use best management practices when disposing of the green waste and yard debris generated from this area.
Currently, the Oregon Department of Agriculture has detected over 12,000 adult beetles from our detection grids. Roughly 2% of these beetles have been found outside of the treatment area. The core of the infestation is located at the center of the treatment area, west of Saltzman Rd and Hartford St, in the Cedar Mill area. Some areas have a sporadic distribution of traps with beetles, possibly the result of beetles being transported on vehicles. However, one trapping area captured beetles consistently throughout a new area, which could indicate low-level infestation and may warrant expansion of the treatment and quarantine boundary in 2018. We will begin to analyze the information from this year’s surveillance activity to help us develop the 2018 response plan for year two of the eradication project, which begins spring of 2018. The Oregon Department of Agriculture will be seeking greater community support and likely additional funding to have a chance at eradicating this unprecedented amount of Japanese beetles in the Pacific Northwest. PLEASE NOTE: THIS POST IS AN ARCHIVE FROM 2017. Oregon Department of Agriculture survey technicians have been busy placing traps throughout the state. All traps were in place prior to peak flight of adult beetles and now the traps are being checked and the lures are being replaced. Traps were placed in high densities over a large area to gather specific information about the Japanese beetle population. These traps are green with a funnel and a catch can. They hang on a metal pole set into the ground near hosts such as turf, roses, or grapes. Japanese beetle traps are baited with a synthetic female sex lure called a pheromone. The traps also have a floral food lure in addition to a pheromone lure.

In order to keep Japanese beetle from spreading while the adults are actively feeding and breeding aboveground, the ODA has established a yard debris quarantine in the area of Cedar Mill and Bethany. As part of the quarantine, residential yard debris including grass clippings, plants with soil, and sod must be contained and placed in curbside yard debris bins or transported directly to the drop off site at Northwest Landscape Services. Compost and transfer facilities are not allowed to accept yard debris from the quarantine area. These containment efforts are necessary to keep the infestation from spreading by way of current waste management practices. To learn more, please visit our Prevention page.
PLEASE NOTE: THIS POST IS AN ARCHIVE FROM 2017. People should expect to see an abundance of Japanese beetles in the quarantine area this summer. As adult beetles begin to emerge from the turf, you can see them feeding on the leaves of a variety of garden and landscape plants. In the weeks to come, adult beetles will lay eggs in areas treated by Oregon Department of Agriculture (ODA). Grubs that hatch deep into treated turf will ingest the granular insecticide Acelepryn applied over the 1,000-acre area and not survive to complete another generational cycle. It is anticipated that subsequent annual treatments will become smaller until the entire population of Japanese beetle in the area is eradicated.
If you see the adult Japanese beetle within the treatment area then the Oregon Department of Agriculture advises that you dispose of them in a container of soapy water. If beetles are observed outside the treatment area please put the specimen in a container or bag and email or call ODA at the contact information provided below.

As of mid-June 2017, the primary larvicide treatment for the eradication of Japanese beetle by the Oregon Department of Agriculture has concluded for year one. In all, 99.9% of the landowners have cooperated with the eradication project. This project represents a grassroots dedication to preserving ecological and community health from this destructive invasive species. The Oregon Department of Agriculture is thankful for the support and participation of over 70 individuals, representing 34 organizations, and the residents of Cedar Mill that have made the first year of this project a success. We need your consent and your support! Japanese beetle has been found in the Cedar Mill neighborhood. The Oregon Department of Agriculture (ODA) is trying to get rid of it before it becomes a problem for everyone in Oregon and negatively impacts Oregon’s agricultural industry.
ODA has been tasked with demonstrating public support for the Japanese beetle eradication project. Residents will be receiving mailers today and tomorrow with a link to an online consent form as well as a consent form that can be mailed to ODA. Residents only need to fill out one or the other, not both. To help residents learn about the project, ODA will be going door-to-door on March 16, 18, 23, and 25 to answer questions and collect consent forms. We’ll be ready to answer questions and to collect your consent forms. ODA will also have a table at Bales Thriftway all day March 18 and 25 and at the Cedar Mill Library in the afternoon on March 18 and 25. ODA needs to start treatment soon for Japanese beetle—both for timing of the targeted insect stage AND getting rid of the beetles before the population becomes too widespread. Now is the time to demonstrate support and sign your consent. |
