Oregon Department of Agriculture (ODA) routinely conducts extensive survey programs for
gypsy moth (GM, Lymantria dispar) and its Asian strain (Asian gypsy moth, AGM). Both moths
can be detected with the same trap and lure.
ODA placed 3,970 GM and 11,165 AGM traps (total 15,135 traps) throughout Oregon in 2017.
Thirty one out of 36 counties were trapped for either GM, AGM or both. In addition, USDA
APHIS placed 81 AGM traps in high risk areas of Port of Portland environs. Eleven GM were
trapped statewide from four counties including: Multnomah County (Portland, three moths),
Benton County (Corvallis - four moths, and Philomath – one moth), Lane County (Eugene – two
moths) and Josephine County (Cave Junction – one moth). All eleven moths were trapped at new
sites. We did not catch any moths from any old sites including Grants Pass where we trapped
GM four years in a row (2013 - two GM, 2014 – four GM, 2015 – seven GM, 2016 – four GM).
We also did not catch any moth from the Asian gypsy moth eradication area in Portland where
8674 acres were sprayed with a biological pesticide Bacillus thuringiensis var. kurstaki (i.e.,
Foray 48B) by air in the spring of 2016. Delimitation trapping will be conducted in 2018 at all
sites where gypsy moths were caught in 2017 and 2016.
AGM populations in Asia and the Russian Far East continue to pose a threat to the US and
Oregon. International trade and commerce activities increase the likelihood of new introductions.
ODA trapped two Asian gypsy moths near Port of Portland in 2015 and conducted an eradication
program in 2016. Follow-up delimitation trapping started after the eradication spray program in
2016 and has continued in 2017. AGM trapping program included major cities, ports, highways,
and railroads receiving or transporting cargo and containers originating from Asia. We also
incorporated the USDA APHIS AGM risk model into our trapping grid allocation. We placed
11,165 AGM traps in 2017 concentrating on AGM eradication site in Portland. Major ports and
waterways at risk from ships carrying AGM egg masses were trapped including about 90 miles

of the Columbia River (from Astoria to Portland), the Port of Portland and the Port of Coos Bay
(Coos County).
Follow-up trapping did not detect any AGM or GM in the eradication area in Portland, indicating
the eradication effort was a success. No eradication treatments are planned for 2018 anywhere in
Oregon. However, the AGM eradication site in Portland will be trapped for one more season
(2018) before a complete eradication can be declared.
