2017 RESULTS OF THE SURVEY ON THE CURRENT STATUS OF DENGUE VECTOR...

2015-2017 Results of the survey on the current status of dengue vectors in 2 communes of Dien Khanh district obtained 2 species of Aedes mosquitoes, namely Ae.aegypti and Ae.albopictus, in which Ae. aegypti is the dominant species with 93.38% of the Aedes mosquitoes collected. Ae.albopictus mosquito makes up only a small proportion of 6.62%. It can be seen that in the area bordering Nha Trang city, where there are highly endemic dengue, Ae.aegypti mosquitoes are the majority with high densities among a few species of the same species in the study area of Dien Khanh district. The survey results are consistent with research of author Truong Thi Lan Anh (2013) in Khanh Hoa province in which Ae. aegypti is the dominant species with 100% of the mosquitoes caught in the study site. The appearance composition of mosquito species Ae.aegypti predominates in highly endemic areas not only in Khanh Hoa but also in the North and the South [124]. Research on the Aedes mosquito species composition and density is also published by many scientists, author Leta (2018) analyzed the role of Ae.aegypti mosquito in the transmission of dengue and competition for environment for reproduction and development [46]. Barrera (2019) also had similar results with species composition and reproductive characteristics, mosquito behavior Ae.aegypti [128] People set up a vase of Phat Loc buds with the desire for a full life. The vase is often placed on the altar and changes water rarely. Washing the flowerpot is not very frequent due to beliefs about restricting touching the altar area. This explains the reason, the density of larvae and mosquitoes Ae.aegypti is always in the house all year round and dengue does not decrease. The density of mosquitoes and larvae of Ae.aegypti and the typical source of a flowerpot was mentioned by author Nguyen Huu Tai (2019) in the study Situation and some factors related to larvae and mosquito populations. transmission of dengue dengue in Dien Loc commune, Dien Khanh, Khanh Hoa in 2019 [129].
