“…29 Other field and laboratory evidence shows that different mosquito species tolerate pH levels from lower than 4 up to 10.5. 69 Therefore, although there are some reports regarding the correlation between pH and the larval density of mosquitoes, 70,71 it is believed that it does not exert a direct effect on the distribution of mosquitoes. 69 The present study reported the mean dissolved oxygen level for the larval habitats of 18 mosquito species in Chaharmahal and Bakhtiari province.…”

Background and aims: Mosquitoes (Diptera: Culicidae) are still a focus of research because of their role in the transmission of diseases and annoying biting behavior. Source reduction is an effective measure to control mosquito populations, which is based on good knowledge of larval habitats. This study was conducted to obtain that basic knowledge in Chaharmahal and Bakhtiari province. Methods: This study was carried out in 2011 and 2012. Geographical coordinates, altitude, pH, temperature, and the dissolved oxygen level of larval habitats were recorded by relevant devices, followed by documenting physical attributes by direct observation. In addition, the indices of biodiversity were calculated to analyze the vertical biodiversity of species. Finally, the affinity index was calculated to elucidate species co-occurrence. Results: Eighteen species were recovered from 92 larval habitats. Low- (≤ 1400 m), mid- (1401–2000 m), and high- (≥ 2001 m) altitudes lodged 7, 17, and 14 species, respectively. Further, the indices of the species richness and biodiversity for these altitudinal categories were 0.93, 1.94, and 1.58, as well as 1.54, 2.13, and 1.96, respectively. Larval habitats were mostly natural, temporary, with standing but clear water, muddy substrate, sunlit, and with vegetation. Other physicochemical characteristics and affinity of species were described and discussed as well. Conclusion: To the best of our knowledge, this is the first report of vertical distribution and biodiversity of mosquito larvae in Iran. The relative uniformity of physicochemical characteristics of larval habitats was attributed to prevailing water resources in the studied area and sampling design. The oviposition site selection of gravid mosquitoes is still an unresolved problem which needs further investigations.

“…Additionally, water is essential for breeding mosquitoes and therefore affects the growth and development of larval stages. Some compounds such as sodium, potassium, calcium and dissolved oxygen have a significant correlation with the density of specific species (Sasikumar et al 1986;Piyaratne et al 2005;Surendran and Ramasamy 2005). Lotfi (1970Lotfi ( , 1973Lotfi ( , 1976 studied ecological aspects like water temperature and pH of the breeding places of Culex species.…”

Abstract. Doosti S, Yaghoobi-Ershadi MR, Sedahhat MM, Akbarzadeh K, Godwin GN. 2021. Larval habitats characteristics of Culicinae subfamily in southern of Iran. Nusantara Bioscience 13: 194-201. Globally, mosquitoes (Diptera: Culicidae) are known vectors of many diseases such as Malaria, Dengue fever, Sindbis, West Nile virus, Rift Vally fever, Japanese encephalitis, and Filariasis. This study aimed to determine larval habitat characteristics of mosquitoes in the southern part of Iran during 2009-2013. The study was carried out in mosquitoes' larval habitats, and samples were collected using dipping and pipette methods. The larvae were kept in lactophenol solution and transferred to the laboratory of Medical Entomology. Then, microscopic slides were prepared and species were identified using reliable morphological keys. Characteristics of larval breeding places were investigated based on the habitat type, water conditions, vegetation, and sunlight exposure. A total of 8188 mosquito larvae were collected from 209 different breeding places. In all, 20 mosquito species belonging to 4 genera were identified. Culex quienquefaciatus, Cx. pipiens, Culiseta longiareolata, Cx. tritaeniorhynchus, Cx. sitiens, Cx. theileri and Aedes caspius were the most common species found in this study. The southern part of Iran has the most wharfs and airports across the country. Additionally, there is a high diversity of medically important mosquito species like Cx. pipiens and Cx. tritaeniorhynchus, Ae. albopictus and Ae. vexans from the Culicidae family. The species are capable of vectoring various diseases in the southern part of Iran; hence, there is a need for more investigations.
