老挝按蚊种类及分布调查

Investigation on the distribution of Anopheles species in Laos

目的调查老挝按蚊种类及分布情况,为当地媒介控制策略及措施的制定提供依据。方法2012-2019年采用成蚊诱蚊灯捕捉法和幼虫勺捕法在老挝10省开展按蚊种类调查,并结合以往老挝蚊虫调查相关文献,确定老挝按蚊种类、孳生环境、地理分布及其医学重要性。结果捕获老挝按蚊隶属2亚属53种,其中,大劣按蚊、微小按蚊、多斑按蚊、中华按蚊、吉甫按蚊、乌头按蚊、菲律宾按蚊及雪足按蚊属于老挝疟疾媒介按蚊。结论老挝按蚊种类丰富,多种疟疾媒介按蚊共存,建议老挝相关部门应加强对媒介按蚊的监测及控制,以确保实现2030年消除疟疾目标。

Objective To investigate the compositions and distributions of Anopheles species in Laos,providing the basis for formulating effective strategies and measures for vector control.Methods Species checklist,breeding environment,distribution and medical importance of Anopheles were determined by CDC light traps collecting adult Anopheles mosquitoes and spoon method collecting Anopheles larvae in 10 provinces of Laos from 2012 to 2019,in combination with previous mosquitoes investigation literatures in Laos.Results A total of 53 Anopheles species of 2 subgenus were captured in Laos.Among them,Anopheles dirus,Anopheles minimus,Anopheles maculatus,Anopheles sinensis,Anopheles jeyporiensis,Anopheles aconitus,Anopheles philippinensis and Anopheles nivipes were malaria vectors in Laos.Conclusion There were plenty of Anopheles species in Laos with multi-malaria vector species coexistence,suggesting that relevant department should be strengthened to surveillance and control of Anopheles vectors for ensuring the goal of eliminating malaria in 2030 in Laos.
