First Record of Aedes japonicus japonicus in Oklahoma, 2017

In spring 2017, mosquito larvae were collected from 25 sites across eastern Oklahoma as part of a Zika virus vector surveillance effort. Aedes japonicus japonicus larvae were collected from horse troughs at 2 sites in Ottawa County, OK. Identification was made using 1 larva stored in 70% ethanol and 3 adult females reared from the larvae. Another invasive mosquito species, Culex coronator, was detected at 2 different sites, adding 2 additional counties to the 9 where the species had been previously reported. The presence of these invasive species in Oklahoma may have an impact on future regional arbovirus concerns.
