Vivax malaria is a significant military and civilian health threat in northern Republic of Korea (ROK). Mosquito collections were performed at two ROK army installations, Paju near the demilitarized zone (DMZ) using black light traps in 2011. The DMZ, a 4 km wide border, is the northernmost point of the ROK and separates the ROK from the Democratic People's Republic of Korea (DPRK). spp. were identified by polymerase chain reaction and screened for sporozoites. Of 4,354 female mosquitoes identified, (61.8%) was the most frequently collected, followed by (16.0%), (9.0%), (7.4%), (4.2%), and (1.6%). , , and showed the highest population densities in June, whereas population densities were highest for , , and in August. The maximum likelihood estimation (estimated number of positive mosquitoes/1,000) for was highest for (28.9), followed by (23.3), (15.8), (9.6), (5.8) and (4.2). The seasonal maximum likelihood estimation (MLE) values were variable among species. , , and showed the highest seasonal MLE's in July, whereas and exhibited the highest seasonal MLEs in September and during August. This is the first report implicating as a vector of in the ROK, and extends our knowledge of the distribution and potential role in malaria transmission.
