Objective To investigate mosquito fauna and habitats in the north of Laos and provide evidences for clarification of mosquitoes, prevention of mosquitoes borne diseases and take advantage of biological resources. Methods Seven counties of five provinces in the north of Laos were chosen randomly from August to October in 2014 and 2015. Adult mosquitoes were collected by overnight trapping with ovitrap light and larvae were collected in the different breeding sites. All captured mosquitoes were processed in the lab. Results In total, 5 921 adult mosquitoes and 3 526 larvae were collected from 82 species of 19 subgenera of 15 genera in 3 subfamilies. All captured adult mosquitoes from 37 species of 11 subgenera of 10 genera in 2 subfamilies were collected by overnight trapping with ovitrap light. The predominant species was Culex tritaeniorhynchus(3 925, 66.29%). Besides, collected larvae belonged to 59 species of 17 subgenera of 12 genera in 3 subfamilies. Culex tritaeniorhynchus was still the predominant species(751, 21.30%). In total, 636 larval habitats of seven different environments were investigated. The predominant habitats were bamboo tube and tree hole(162) and wasted tires(153), these three habitats accounted for 49.30%(315/636)in all habitats. Conclusion The mosquito species showed biological richness in the north of Laos. The predominant species was Cx. tritaeniorhynchus, followed by Anopheles argyropus, An. minimus, An. sinensis, Aedes albopictus, Armigeres subalbatus and Ae. aegypti. The diversity and complexity of habitats of larvae were observed. Different mosquito larvae preferred different habitats, but symbiotic phenomenon of various mosquito species commonly existed.
