Determination of Mosquitoes Fauna (Culicidae: Diptera) in Poldokhtar County of Lorestan Province, 2015

Insects as the largest category of arthropods include numerous groups and families that the most important of them belong to order Diptera, family Culicidae. Because of feeding on the human's blood, a number of species of this family have been known as responsible for the transmission of pathogens for many diseases such as malaria, filariasis, encephalitis, yellow fever and dengue fever in the world. Given that no research has been conducted to determine the fauna of existing mosquitoes in the city of Poldokhtar, Lorestan Province, the present study aimed to exactly determine the mosquitoe's fauna in this city to perform appropriate prevention measures.
In this faunistic and cross-sectional descriptive study, four urban areas and four rural areas in four geographic directions in the city of Poldokhtar were determined. In each urban area, two places and in each designated rural area, four places including two human places and two animal places were selected. From the early of April 2015 to the early of January 2016, larvae, pupae and adult mosquitoes of the Culicidae family were collected. Sampling methods for larvae, pupae and mature were ladling, night catch, total and hand catch with an aspirator. Characteristics including the name of the collector, date of collection, code related to habitat, habitat status (permanent or temporary), type of vegetation cover, type of substrate, and the situation of sunlight were recorded in the related form. The samples were identified by resources and valid identification keys. The data were analyzed using the SPSS software version 19.
Totally, 5392 mosquito adults of the Culicidae family including 1818 mosquito adults and 3574 larvae in designated areas in the city as well as four rural areas were collected. The three genera Anopheles (21.9%), Culex (64.6%), and Culiseta (13.5%) were diagnosed. Also, from three genera, 12 species were identified as follows: Culex theiler, Cx. mimeticus, Cx. perexiguus, Cx. hortensis, Cx. pipiens, Cx. sitiens, Cx. tritaeniorhynchus, Culiseta langiareolata, Anopheles superpictus An. stephensi, An. turkhudi and An. dthali.Culex pipiens (19.9.5%) and Culex theileri (19.5%) were the most abundant species, respectively.
The results of this study indicate the presence of various species of mosquitoes throughout the city of Poldokhtar. Also, the results can lay the groundwork for doing more comprehensive and special studies particularly regarding the possible role of different species of mosquitoes in human and animal health in the future.
