BACKGROUND
Mosquitoes are important insect vectors, but whether they can carry and transmit African swine fever virus (ASFV) in large-scale pig farms in China is unknown.
RESULTS
In this study, probe-based qPCR analysis was performed on mosquitoes from five pig farms with ASF virus (ASFV). Analysis of ASFV in 463 mosquitoes yielded negative cycle threshold (CT) value), and detection remained negative after mixing samples from all five pig farms.
CONCLUSIONS
Therefore, mosquitoes appear unlikely to transmit ASFV, and pose little threat to large-scale pig farms. Thus, farms should continue to follow normal mosquito control procedures when formulating strategies for the prevention and control of ASF.
背景
蚊子是重要的昆虫传播媒介，但在中国大规模养猪场，它们是否能携带和传播非洲猪瘟病毒（ASFV）尚不清楚。
结果
本研究对来自五个发生非洲猪瘟病毒（ASFV）的养猪场的蚊子进行了基于探针的 qPCR 分析。对 463 只蚊子的 ASFV 分析得出了阴性循环阈值（CT 值），并且在混合来自所有五个养猪场的样本后检测仍然为阴性。
结论
因此，蚊子似乎不太可能传播 ASFV，对大规模养猪场的威胁较小。因此，在制定非洲猪瘟防控策略时，农场应继续遵循正常的蚊子控制程序。
