摘要
目的调查老挝琅勃拉邦省蚊虫种类组成及重要生态习性,为当地制定有效的媒介控制策略及措施提供参考。方法2022年11月,在老挝北部琅勃拉邦省采用诱蚊灯通宵捕蚊法、人工帐诱捕法和人牛房全捕法采集成蚊,采用勺舀法捞捕居民周边小积水伊蚊四龄幼虫,采集的成蚊和伊蚊幼虫通过形态学方法进行种类鉴定并登记。结果共捕获成蚊2亚科6属29种2149只,其中三带喙库蚊和乌头按蚊属当地优势种,分别占捕获总数的19.48%(419/2149)和16.54%(345/2149);共捕捞伊蚊幼虫1属2种14条,其中埃及伊蚊和白纹伊蚊占比分别为85.71%(12/14)和14.29(2/14)。微小按蚊和多斑按蚊通宵均有叮咬活动,叮咬高峰分别主要出现在子夜(00:00-01:00)和黄昏(20:00-21:00)。结论老挝琅勃拉邦省蚊虫种类丰富,三带喙库蚊为优势蚊种,同时存在具有夜间叮咬活动的微小按蚊,以及埃及伊蚊和白纹伊蚊,提示当地仍然存在疟疾、登革热和流行性乙型脑炎疫情风险,建议加强对上述疾病的监测。
Objective To investigate the species composition and ecological habits of mosquitoes in Luang Prabang Province,Laos,providing the reference for local formulating effective vector control strategies and measures.Methods In November 2022,adult mosquitoes were collected using the light-trap method(overnight)、trapping mosquitoes with human nets method and indoor resting and cattle collection method,fourth-instar Aedes larvae were collected by spoon scooping method in small stagnant water around residents in Luang Prabang Province of northern Laos,and all collected adult and larvae mosquitoes were identified and registered by morphological methods.Results A total of 2149 adult mosquitoes were captured,belonging to 29 species in 6 genera from 2 subfamilies,of which Culex tritaeniorhynchus and Anopheles aconitum were local dominant species,accounting for 19.48%(419/2149)and 16.54%(345/2149)of the total captures,respectively.A total of 14 aedes mosquito larvae were caught,belonging to 2 species in 1 genus,and the proportions of Ae.aegypti and Ae.albopictus accounted for 85.71%(12/14)and 14.29(2/14),respectively.Both An.minimus and An.maculatus have overnight biting activity,with their biting peaks occurring mainly at midnight(00:00-01:00)and dusk(20:00-21:00),respectively.Conclusion Luang Prabang province of Laos had abundant mosquito species,with Cx.tritaeniorhynchus as the dominant species,and there are An.minimus,Ae.aegypti and Ae.albopictus,indicating that there were high risks of malaria,dengue fever and Japanese encephalitis outbreaks in the local area,and it was recommended that local relevant departments strengthen the surveillance of the above diseases.
