The invention relates to an appliance for identifying and detecting animal viruses belonging to flaviviridae pestiviruses and in particular relates to hog cholera virus and bovine viral diarrhea virus identification and detection test paper. The test paper consists of a supporting plate, a sample pad, a gold-labeled pad, a detection film and an absorbent pad, wherein imprints of a hog cholera virus detection line T1 shaped like a vertical line, a bovine viral diarrhea virus detection line T2 shaped like a vertical line and a quality control line C shaped like a vertical line are arranged on the detection film. During identification and detection, when three red stripes shaped like three vertical lines present on the detection film, the sample is infected with the hog cholera virus or immunized by a hog cholera virus vaccine, and is also infected with the bovine viral diarrhea virus; when two red stripes shaped like two vertical lines present on the hog cholera virus detection line and the quality control line, the sample is infected with the hog cholera virus or immunized by the hog cholera virus vaccine; when two red stripes shaped like two vertical lines present on the bovine viral diarrhea virus detection line and the quality control line, the sample is infected with the bovine viral diarrhea virus; and when only one red stripe shaped like a vertical line presents on the detection film, the sample is negative to the hog cholera virus and bovine viral diarrhea virus. The identification and detection test paper is high in specificity, high in sensitivity, wide in response spectrum and easy and convenient and rapid to operate, can be widely applied to identifying and detecting the hog cholera virus and bovine viral diarrhea virus and is easy to popularize and apply in production practice.
