Abstract

Aedes aegypti (L.) mosquitoes (Diptera: Culicidae) have a great importance in public health. Aedes- borne diseases (ABDs), especially the dengue virus (DENV) has increased and spreaded worldwide. The study is one of a series of studies aimed to map Aedes species in the Sudan and determine some aspects of their ecology in Ed Daein town, Ed Daein Locality, East Darfur state (EDS), Sudan. A cross-sectional survey during July 2016 - June 2017 was conducted to determine seasonal and geographical distribution, larval habitats of Aedes mosquitoes. Five sentinel sites/neighborhoods/residential areas, namely, Alarab, Almatar, Alnahda, Alguba and Moasker Alneem with different environmental settings were selected as urban and periurban areas. In each neighborhood, water containers in houses and larval habitats were surveyed for larvae and pupae of Aedes spp. In each household (HH), all water containers were checked for the presence (positivity) of these immature stages of Aedes spp. to describe the larval habitats, their distribution, seasonality and calculate Stegomyia indices, i.e. the house index (HI), the container index (CI), Breteau index (BI) and pupal/demographic index (P/DI). Larvae and pupae from different habitats were also sampled, preserved in 70% ethanol in Eppendorff tubes for species identification. From a total of 382 (89.8%) larvae, were identified as Ae. aegypti, while 10.2% were identified as Ae. albopictus. From 3,243 containers inspected, 8.2% were found positive for Aedes species. The highest percentage of positivity was found in clay pots (zeers) containers (77.9%), followed by barrels (20.2%). High occurrence of larvae and pupae was shown in Alnahda neighborhood with mean of 6.5/5 dips and 2.2/5 dips, respectively. The number of pupae was significantly different in all study sites. The highest mean number of larvae was found to be (10.1/5 dips) in rainy-season in comparison to the dry- season while the high mean umber of pupae was (3.3/5 dips). No significant difference was found between HI during the different months of the study. The highest HI was recorded in July 2016 (98.2%). Significant differences between BI, CI and P/DI, during different months of the study were detected. The high BI was detected in October 2016 (30.0%), High CI was reported in November 2016 (13.9%) and the highest P/DI was recorded in October 2016 (15.7%). Ae. aegypti was the prevalent species in the study sites. Zeers and barrels were the key containers for the Aedes species breeding. Large-scale studies on spatio-distribution of Aedes mosquito in the remain localities of East Darfur State is highly recommended in near future.
