Taxonomic and Biodiversity Study of Sandfly Species in the Fez Region, Central Morocco doi.org/10.26538/tjnpr/v6i6.12
Main Article Content
Abstract
Leishmaniasis is a parasitic disease caused by infectious protozoa of the genus Leishmania that are transmitted by the bite of phlebotomine sandflies. However, there has not been any taxonomic study on sandfly biodiversity in the Fez Province. This study was aimed at identifying and making an inventory of the most common sandflies in the different regions of the Fez Province. Sandfly collection was done twice a month with sticky traps from May 2017 to April 2018. Spatial distribution analysis was performed using Qgis 2.18 software. A total of 816 sandflies were collected, with a male predominance (sex ratio of 20.47) and divided into two genera: Phlebotomus (46.82%) and Sergentomyia (53.18%). The predominant species of the Phlebotomus genus were P. sergenti (26.96%), followed by P. perniciosus (10.78%), and P. papatasi (9.07%). Sergentomyia minuta was the most dominant species compared to the other specimens with a proportion of (44.24%) followed by S. fallax (7.97%), and S. antennata (0.98%). GIS analysis revealed that Ain Nokbi, Boujloud, Dhar Richa, and Zlilig are likely to be sandfly biotopes. The prevalence of Phlebotomus species with a large distribution area in the prefecture of Fez and high population numbers could explain the reasons for the cutaneous leishmaniasis observed in the study period. These observations implicate Fez Province as having a significant risk of leishmaniasis transmission. The findings of this study can assist in implementing appropriate control measures for Fez regions by developing a comprehensive leishmaniasis risk map.
