目的：了解嗜人按蚊向江汉平原区延伸的范围。方法：以浅丘平原结合部嗜人按蚊村点为起点向江汉平原腹地垂直定点、定距离调查，捕捉人房及帐内按蚊，按照蚊卵及成蚊形态鉴定蚊种。结果：共调查２４个村点，捕按蚊２９８８只，除在原嗜人按蚊村点发现嗜人按蚊外，相距嗜人按蚊村点２～４０ｋｍ、面积约２６０ｋｍ２内均未发现该蚊。结论：浅丘与平原结合部的嗜人按蚊未向江汉平原腹地延伸。
Objective: To understand the range of Anopheles anthropophagus extending to the Jianghan Plain. Methods: Anonymous Anopheles junctions at the junction of shallow valleys were used as the starting point to survey the hinterland of Jianghan Plain vertically, and to survey the anteater and Anopheles mosquitoes. The mosquito species were identified according to the mosquito eggs and adult mosquitoes. RESULTS: A total of 24 villages were spotted with 2988 Anopheles mosquitoes. In addition to the discovery of Anopheles anthropophagus at the sites of Anopheles anthropophagus, the mosquitoes were found within 2 ~ 40km from the Anopheles anthropophagus and within an area of about 260km2 . Conclusion: Anopheles anthropophagus in the junction of shallow hill and plain did not extend to the hinterland of Jianghan Plain.
