Abstract: In recent years,exotic insect-borne diseases,such as African swine fever,nodular dermatosis have infected China.However,the risk of some insect-borne pathogens,such as African horse plague,which have been popular abroad,being introduced into China is becoming higher and higher,seriously endangering the development of animal husbandry and public health safety in China.Especially since August 2018,the prevalence of African swine fever in China has brought important warning information to the pig industry,that is,to prevent the entry of vectors in pig farms and block the transmission of pathogens will become the focus of pig farms' biosafety.Mosquitoes,flies,midges and ticks are important vector factors for the transmission of epidemic diseases in pig farms and infected pigs.The types of vectors and the pathogens isolated from vectors,such as viruses,bacteria and parasites,are complex.The differences of biological characteristics of vectors have different effects on the transmission mode and transmission ability of pathogens.In view of this,the author summarized in detail the main types of insect vectors existing in pig farms and the important pathogens of swine diseases,including Porcine encephalitis B virus,Porcine reproductive and respiratory syndrome virus,African swine fever virus,Gatah virus,Swine enteric coronavirus,Escherichia coli,Streptococcus suis,and so on,and discussed their harmfulness and transmission risks,so as to reduce the economic losses caused by insect borne diseases in pig farms loss.

Key words: pig farm; insect vector; transmitted pathogen
