الملخص

Vector-borne diseases (VBDs) represent a major public health problem in the world, especially sub-Saharan Africa, including Sudan. Among insects, mosquitoes (Diptera: Culicidae), are the most important group in the transmission of several human diseases, including malaria, yellow fever, dengue, encephalitis and filariasis. The goal of this study to identify mosquito larval habitats in urban, rural and island areas of Dongola locality, Northern State, Sudan, identify the mosquito species found in the areas, determine the different breeding habitats and estimate the larval density for each habitat, during April 2015 to March 2016 in three selected areas; urban, rural and island. The study areas were Aldarga althaltha, Sortod and Magaser. Larvae were collected from any positive breeding habitats and taken to the laboratory, killed and preserved in 70% ethanol and mounted for identification by microscope. A total of 338 aquatic habitats were sampled throughout the study period; about 235 (69.5%) were positive breeding habitats. A total of 1418 mosquito larvae were collected from different larval habitats, 41.1% were identified as A. arabiensis, 30.4% as C. quinquefasciatus, and 28.5% as C. univittatus. About 14 different types of mosquito breeding habitats were found in the study area. The highest frequency of A. arabiensis habitats were brick work pool (77.8%), irrigation channel (75%), and broken pipe (40.9). For Culex species habitats were bird container (80%) and septic tanks (73.1%). Man-made mosquito breeding habitats recorded the highest proportion in the urban area, while the natural habitats were the highest in rural and island areas. Outdoor mosquito breeding habitats recorded the highest proportion from positive habitats in the rural and island areas, while indoor breeding habitats were the highest proportion in the urban area. The highest density of A. arabiensis was in September to November, and highest density of Culex spp was in September in the rural and island areas, and between November to March in the urban areas. Water current, water depth, presence of light, pH and vegetation, were the principal factors associated with mosquito species larval occurrence in the habitats. It is recommended to conduct more studies about mosquito in the area, especially Culex species and its medical importance in diseases, because a few studies were conducted there. Larval source management is an appropriate way to control mosquitoes. Pesticides usage in the area, especially in the agricultural activities, needs to improve their management, especially after increasing agricultural investments in the state, to avoid development of resistance in public health insects.
