Objective: To determine spatial distribution of sand flies(Diptera: Psychodidae; Larroussius group), the vectors of visceral leishmaniasis in Ardabil province, Northwest of Iran.Methods: Sand flies were collected using sticky traps from the 30 selected points in Ardabil province, during May-November 2017.The MaxEnt model in GIS software was used for modeling.Results: A total of 2 794 specimens of sand flies were collected, of which 33% were Larroussius subgenus sand flies.Phlebotomus kandelakii and Phlebotomus wenyoni were the highest and lowest collected species respectively.Based on the modeling, four areas in the province were identified with more than 70% probability of the presence of Larroussius group vectors which were at risk of visceral leishmaniasis disease transmission.Conclusions: The distribution of Larroussius subgenus sand flies was observed in all parts of Ardabil.But the northern parts of the province(Germi and Bilesavar counties) as well as central part(Ardabil and Meshkinshahr counties) were of great importance in terms of the presence of Larroussius subgenus sand flies and the possibility of transmission of the visceral leishmaniasis. 展开更多

Objective: To delineate reliable morphological characteristics for identifying and separating female Phlebotomus caucasicus and Phlebotomus mongolensis which exist sympatrically in the main foci of zoonotic cutaneous leishmaniasis in Iran.Methods: Sand flies were collected using sticky trap papers from active colonies of rodent burrows installed from 16 catching sites. Morphometric measurements were analyzed of 87 Phlebotomus caucasicus and 156 Phlebotomus mongolensis. Univariate and multivariate analysis were carried out to determine significant morphometric variables for discrimination of the two species. Finally, seven morphological characteristics of 65 female Phlebotomus caucasicus and 124 female Phlebotomus mongolensis were described.Results: Univariate and multivariate analyses of 10 morphometric variables via Discriminant Function Analysis(DFA) and Principal Component Analysis(PCA) showed that five morphometric variables had an accuracy of 100% for discriminating female Phlebotomus caucasicus and Phlebotomus mongolensis. Moreover, PCA revealed that the five morphometric variables with the highest loadings separated these two species. Morphological studies on antennal flagellum(and its associated structures) and mouth-parts of female specimens demonstrated significant differences in several structures.Conclusions: The results show that morphological and morphometrical features can be used to discriminate two female isomorphic species, Phlebotomus caucasicus and Phlebotomus mongolensis accurately. 展开更多

Objective:To determine both the distribution and the ecological characteristics of sand flies in Golestan Province,northeast of Iran in 2016.Methods:In this study,34 villages were selected based on their geographical conditions.Sticky paper traps were used for collecting the sand flies.Sampling was carried out in each of villages from May to November.In each village,60 traps for indoors and 60 for outdoors were monthly installed.The species of all collected sand flies were determined using approved morphological keys.Pearson coefficient correlation was used to find the relationship between the number of collected Phlebotomus papatasi from different villages and incidence rate of zoonotic cutaneous leishmaniasis as well as the number of positive cases of the disease.The altitude of the studied villages was extracted from digital elevation model of the area using GIS and vegetation cover density index of the province was extracted from Modis satellite imagery and distribution map of sand flies drown up.Results:Overall,5 428 sand flies were collected and identified,belonging to 18 species.Phlebotomus wenyoni was reported for the first time from the area in this study.The frequency of sand flies in the villages located in northeast of the Golestan province(the plateau area,lower altitude,arid and semi-arid climates,and lower vegetation cover density),were more than other villages in this province.There was a significant correlation between the number of collected Phlebotomus papatasi and incidence rate of the zoonotic cutaneous leishmaniasis cases in different villages(r=0.837,P=0.019) as well as the number of positive cases of the disease(r=0.688,P<0.001).Conclusions:In the northeaster areas of Golestan Province which is known as the endemic foci of zoonotic cutaneous leishmaniasis,the abundance of sand flies were more and the conditions for their growth and development were more appropriate. 展开更多
