Objective: Identification of vector species and determination of physical and ecological features of their breeding places is essential in implementation of scientific based mosquito control activities. In this study, it is aimed to identify Anopheles species by morphological method and determination of physical and ecological characteristics of their breeding places in Sanliurfa territory. Methods: Mosquito larvae were collected between September 29 and October 03, 2009 from determined 9 breeding places in Birecik, Eyyubiye, Haliliye, Harran, Siverek and Viransehir districts of Sanliurfa province where malaria cases had been reported and four instar larvae were identified morphologically according to keys of DuBose ve Curtin (1965), Merdivenci (1984) and Darsie and Samanidou-Vojadjoglou (1997). Essential ecological parameters of water in breeding places were measured. Temperature and dissolved oxygen were measured by using ExStik® DO600 (Extech Instruments-USA); pH and conductivity were measured by using Hanna Instruments 98129 pH / Conductivity /TDS Tester (Hanna Instruments-Germany) and salinity was measured using ExStik®II EC400 Conductivity/TDS / Salinity/Temperature Meter (Extech Instruments-USA). Results: Of the 274 four instar larvae collected, 231 (%84,3) were identified as An. sacharovi and 41 (%14,96) of them were identified as An. superpictus. Two (0,73%) samples identified as Anopheles genus, species discrimination could not be done. In %88,89 (n=8) of nine breeding places An. sacharovi and in %11,11 (n=1) of total breeding places An. superpictus found to be dominant species according to the morphological results. Malaria vector An. sacharovi detected in all breeding places which had different pH values, dissolved oxygen proportions, electrical conductivity, water temperature and salinity proportions with horizontal vegetation. The limits of tolerance for essential ecological parameters of species found to be as: pH-7,77-9,18 (mean 8,53); electrical conductivity-310-1100 (?S/cm) (mean 496,91); dissolved oxygen (mg/l)-1,64-13,06 (mean 9,67); temperature of water-20,3-25,8 °C (mean 23,46); salinity 0,15-0,55 ppt (mean 0,24). The limits of tolerance for essential ecological parameters of An. superpictus species in study area measured as: pH 8,48; electrical conductivity 710 ?S/cm; dissolved oxygen 8,91 mg/l; temperature of water 25,8 °C; salinity 0,35. In statistical analysis of physical and ecological characteristics of mosquito breeding places; no significant difference between pH values (p=0,189) was found between An. sacharovi and An. superpictus breeding places but significant dif¬ference have been found in water temperature (p= 0,0000001), electrical conductivity (p= 0,0000001), salinity (p= 0,0000001) and dissolved oxygen (p= 0,001) values. Conclusion: An. sacharovi is thought to be considered to be primary malaria vector in Sanliurfa Province as it can become the dominant species in malaria endemic areas and also in areas where transmission reoccur due to its ecological flexibility. In this context, vector control strategies in Sanliurfa should be revised and planning should be done according to the characteristics of the vector. © 2020 Refik Saydam National Public Health Agency (RSNPHA). 2-s2.0-85087319686 |
