Insects as potential vectors of African swine fever virus in the
Republic of Korea
African swine fever (ASF) is a fatal disease in swine. Concentration of
cases over summer and outbreaks in farms with high levels of biosecurity
might support the hypothesis of ASF virus transmission via insects. A
total of 28,718 insects were collected from 14 pig farms affected by ASF
in the Republic of Korea. The insects collected were flies (N = 27,310,
95.1%), mosquitoes (N = 1,198, 4.2%), and cockroaches (N = 24, 0.1%).
The remaining 0.6% (N = 186) could not be taxonomically classified. All
the insects collected showed no trace of ASF Virus-DNA was detected by
laboratory analysis. It is premature to conclude on the role of insects
in the transmission of ASFV. However, the possibility of the virus
spreading via insects should not be overlooked.
