【摘要】：目的掌握遼寧省瘧疾媒介按蚊物種構成、密度、季節(jié)消長和夜間吸血活動規(guī)律,為遼寧省制定消除瘧疾媒介按蚊控制技術提供科學依據(jù)。 方法應用誘蚊燈法、棲息蚊蟲捕捉法和人帳誘法三種蚊蟲密度監(jiān)測方法開展按蚊生態(tài)習性研究；應用PCR方法開展按蚊物種構成研究；應用MPCR方法開展雷氏按蚊蚊胃血血源研究。 結果遼寧省按蚊物種構成以雷氏按蚊和中華按蚊為主,雷氏按蚊在我國分布的最北邊界推移至遼寧省鐵嶺市,緯度為北緯43。26’。遼寧省雷氏按蚊密度高峰季節(jié)為7—9月,與瘧疾發(fā)病高峰相一致,該蚊人、牛血兼吸,吸人血比例1%,夜間吸血活動高峰為21：00—23：00；遼寧省中華按蚊密度高峰季節(jié)為7—9月,夜間吸血活動高峰為19：00—22：00。 結論遼寧省瘧疾媒介中華按蚊和雷氏按蚊分布范圍廣,密度高,雷氏按蚊兼吸人血,具有一定傳播瘧疾的能力。提示應該加強按蚊傳瘧能力的研究,探索有效的按蚊防制方法,降低按蚊傳播瘧疾的危險,消除瘧疾病例。
[Abstract]:Objective to understand the species composition, density, seasonal fluctuation and nocturnal blood sucking activity of malaria vector Anopheles in Liaoning Province, and to provide scientific basis for the establishment of control technology for malaria vector Anopheles in Liaoning Province. Methods the ecological habits of Anopheles japonicus were studied by means of mosquito trap lamp method, mosquito capture method and human mosquito trap method, and the species composition of Anopheles japonicus was studied by PCR method. MPCR method was used to study the gastric blood source of Anopheles thunder mosquito. Results Anopheles aegypti and Anopheles sinensis were the dominant species in Liaoning Province. The northernmost boundary of Anopheles repens in China spread to Tieling City, Liaoning Province. The latitude of Anopheles repens in Liaoning Province was 43.26o.Anopheles density peak season was July to September in Liaoning Province. In line with the peak of malaria incidence, this mosquito population, cattle blood sucking, human blood intake ratio 1, nocturnal blood absorption peak of 21: 00-23: 00, Liaoning Province Anopheles sinensis density peak season is July to September, nocturnal blood sucking activity peak is 19: 00-22: 00. Conclusion the malaria vector Anopheles sinensis and Anopheles repens in Liaoning Province have a wide range of distribution and high density. Anopheles repens has the ability to transmit malaria to a certain extent, which suggests that the study on the ability of Anopheles sinensis to transmit malaria should be strengthened. To explore effective control methods of Anopheles mosquitoes, reduce the risk of Anopheles mosquito transmission malaria, eliminate malaria cases.
