Update on the distribution of Ochlerotatus japonicus in Oregon and Washington.
In 2006, Ochlerotatus japonicus was found in Kelso, WA and Portland, OR. These are the southernmost collections of Oc. japonicus on the west coast of the USA. Though the methods of dispersal are not fully understood, it is evident that Oc. japonicus is expanding its distribution in the Pacific Northwest.
