笔者在不同栖息场所采集Ｃｅｌｌａ氏Ⅱ～Ⅲ期中华按蚊及嗜人按蚊共３５７只，同时用ＥＬＩＳＡ及沉淀试验鉴定蚊胃血中的人、牛血。结果３５７份标本，经沉淀试验人血阳性１２６份，占３５．３％；牛血阳性５９份，占１６．５％。ＥＬＩＳＡ测定人血阳性１３５份，占３７．８％；牛血阳性７５份，占２１．０％。后法较前法阳性率高，阳性反应强度较高。沉淀试验鉴定为人牛血的３０份，ＥＬＩＳＡ测定人血５份，牛血８份，人牛血１７份。沉淀试验鉴为猪血的１３０份，ＥＬＩＳＡ测定为阴性反应。沉淀试验鉴定人、牛血为阴性的１２份标本，经ＥＬＩＳＡ法检测全为阳性反应，其中人４份，牛血８份，进一步证明后法较前法特异性强，更适合现场蚊胃血鉴定。
In this study, 357 Celosia anopheles and Anopheles anthropophagus were collected from different habitats, and the human and bovine blood in mosquito and stomach were identified by ELISA and sedimentation assay. Results 357 specimens, the precipitation test of human blood-126, accounting for 35.3%; bovine blood-positive 59, accounting for 16.5%. ELISA assay of human blood-135, accounting for 37.8%; bovine blood-positive 75, accounting for 21.0%. After the law than the positive rate of positive, high positive reaction intensity. Precipitation experiments identified as human bovine blood 30, 5 copies of human blood by ELISA, 8 parts of bovine blood, 17 parts of human bovine blood. Precipitation test for the pig blood of 130, ELISA assay was negative. Precipitation test identified people, bovine blood was negative in 12 specimens, all detected by ELISA positive reaction, of which 4 were in cattle, 8 copies of bovine blood, to further prove that the latter method is more specific than the former method, more suitable for on-site mosquito blood identification .
