A tick survey was conducted to monitor ticks using tick traps attached dry ice method at each four sites in Ulju and Gimhae counties, Gyeongsangnam-do from April to November, 2023. Two species belonging to one genera were collected with tick traps. A total of 1,064 ticks were collected as Haemaphysalis longicornis (Trap Index; TI 11.0), Haemaphysalis flava (TI <0.1) in Ulju and A total of 843 ticks were collected as Haemaphysalis longicornis (Trap Index; TI 8.7), Haemaphysalis flava (TI 0.1) in Gimhae 2023. Haemaphysalis longicornis was the most frequently collected, representing 99.2% in Ulju, 98.9% in Gimhae. In the collection environments, a total number of 685, 268, 64, and 47 ticks were collected from a glassland, a copse, a mountain path, and a grave of Ulju a total number of 469, 216, 83, and 75 ticks were collected from a glassland, a copse, a Grave, and a mountain path of Gimhae respectively. In the results of the isolation of Severe Fever with Thrombocytopenia Syndrome (SFTS) from the ticks, no pathogens were detected from RNA of 101 pools (Ulju), 98 pools (Gimhae) of the ticks using a Polymerase Chain Reaction method in 2023.

IPCC가 발간한 “지구온난화 1.5℃ 특별보고서에서는 전 지구적인 경제피해, 생태계, 종다양성에대한 피해를 언급하고 있다. 우리나라를 기준으로 보았을 때 평균 기온이 상승하는 경우 가장 우려되는 현상 중 한가지는 매개체들의 서식범위가 북쪽으로 확대되어지고 이에 따라 매개체가 옮기는 질병들에 대한 우려가 매우 크다. 특히 국내에 서식하지 않던 매개체들의 유입 위험이 증가되고 있다. 이에 질병관리청은 16개의 매개체감시거점 센터를 운영하고 있다. 하지만 최근 5년간 매개체 관련 과제 숫자는 감소하고 있어 매개체 감시의 중요성이 대두 되어질 필요가 있다.

A tick survey was conducted to monitor ticks using tick traps attached dry ice and a flagging method at each four sites in Busan, Ulju, and Geoje areas of Gyeongnam Province from April to November, 2018. Haemaphysalis longicornis was the most frequently collected, representing 99.8% in Ulju. A total of 27,247 ticks were collected as H. longicornis (Trap Index; TI 283.2), H. flava (TI 0.3), and Ix. nipponensis (TI 0.3). In the collection environment, a total number of 15,672, 5,798, 4,876, and 901 ticks were collected from glassland, tump, tomb, and mountain path, respectively. On the other hand, H. longicornis and Ix. nipponensis were collected with flaggings at the four sites in Ulju, Busan, and Geoje in May and June, 2018. A total of 1,517 ticks collected H. longicornis (Flagging Index; FI 9.3) and Ix. nipponensis (FI 0.1) in Ulju. Haemaphysalis longicornis were collected 2,183 (FI 13.6) and 1,596 (FI 10.0) in Geoje and Busan, respectively. In the results of the isolation of Severe Fever with Thrombocytopenia Syndrome (SFTS) from the ticks, no pathogens detected from RNA of 557 pools of the ticks using a Polymerase Chain Reaction method in 2018.

Malaria is notorious disease to transmitted by Anopheline mosquitoes. In Korea, Plasmodium vivax malaria was re-introduce in 1993 and exceed to more than 4,000 cases in early 2000s. Based upon our control efforts, it was sharply decreased and diagnosis 576 cases in last year. We made Action Plan in this year for certification of malaria elimination by WHO until year 2024. In this plan, we need to strengthen our capacity of vector surveillance and control. For vector surveillance, we will introduce daily mosquito population monitoring system. In 2020, every malaria high risk area install two mosquito counters and send information to main server. For vector control, we will try building capacity of malaria mosquito control people in the Public Health center and military section. To decrease no. of mosquitoes, we will concentrate our resource to cattle shed, which is main blood source of Anopheline mosquitoes. Based on the ecological characteristic of Anopheline, we will adopt Integrate Vector management (IVM) including physical, chemical and biological method. Based on the reconciliation with North Korea, we will support technical and material support for malaria elimination.

The purpose of this monitoring is to survey the geographical distribution of tick species using dry ice bait traps and flagging methods at each ten provinces (GangwonⅠ,GangwonⅡ, Gyeonggi, Chungbuk, Chungnam, Gyeongbuk, Gyeongnam, Jeonbuk, Jeonnam and Jeju area) and one Metropolitan area in the Republic of Korea for eight months from April through November, 2016. A total of 65,339 ixodid ticks (8,200 females, 1,988 males, 31,453 nymphs and 23,698 larvae) was collected, belonging to three genera (Haemaphysalis, Ixodes and Amblyomma). Haemaphysalis longicornis was the most commonly collected species, which is represented for 96.88% of all the collected ticks and followed by H. flava (2.69%), I. nipponensis (0.35%), A. testudinarium (0.05%) and H. japonica (0.03%) in the Republic of Korea for the study period. Haemaphysalis longicornis was a dominant species observed in these eleven areas.

There are over 3,000 different species of mosquitoes throughout the world; currently 56 species are reported in Korea. Mosquitoes can act as vectors for many disease-causing viruses and parasites during blood sucking. Various species of mosquitoes are estimated to transmit various types of disease to more than 700 million people annually in Africa, South America, Central America, Mexico, Russia, and much of Asia, with millions of resultant deaths. At least two million people annually die of these diseases, and the morbidity rates are many times higher still. To prevent the spread of diseases, KNIH (Korea National Institute of Health) used three categorized methods; identifying or taxonomic analysis of mosquitoes, detecting virus caring mosquitoes, and detecting malaria from Anopheline mosquitoes. We have proved that taxonomic analysis using DNA barcording method (COI gene) is useful to complement identification of mosquito species. In detecting virus, we have reported Cx. orientalis as a new potential Japanese encephalitis virus (JEV) vector. We also reported that the Anopheline mosquito species composition and Plasmodium vivax infection rates in malaria hot spot in Korea.
