Abstract
A nationwide vector surveillance program with early warning system, the 5 bovine arthropod-borne viruses (arboviruses), was initiated in the Republic of Korea. Bovine arboviruses are mainly transmitted by blood-sucking arthropods, such as, Culicoides biting midges and ticks. Aino virus (AINOV) and Akabane virus (AKAV), in the family Bunyaviridae, are among the arboviruses that cause disease outbreaks in cattle. Bovine ephemeral fever virus (BEFV) is classified into the family Rhabdoviridae and is known to cause an acute febrile disease. Chuzan virus (CHUV) and Ibaraki virus (IBAV) belong to the family Reoviridae and cause reproductive disorders, fever and anorexia. This study described results of the arboviruses surveillance conducted by collecting Culicoides biting midges in 2014-2015. Arboviruses vector surveillance was conducted by collecting from 4 sites nationwide in cattle farms. Culicoides biting midges were caught on a weekly basis using a light trap (SNC, Korea). Culicoides species (~60) were pooled into 1 sample and the sample tubes were subjected to RT-PCR for detecting 5 arboviruses. The PCR was performed on by RT-PCR kit (Arbovirus RTPCR, Median diagnostic. Korea). C. punctatus was the most commonly collected species (51.1%), followed by C. arakawae (40.0%) and C. maculatus (8.6%). A total of 174 pooled samples of Culicoides biting midges were tested to detect the presence of arboviruses: CHUV was detected in July, Jeonju City; but it did not provide the precautionary attention level at detection rate. The detection rate of the Culicoides biting midges is one of the important factors to predict the possibility of outbreak of arbovirus diseases. By analyzing the surveillance data, the livestock producer can be provided with vital information on when and where arboviruses are active, which may be helpful to prevent potential outbreaks.
