Seasonal distribution study of mosquito species (Culicidae: Diptera) in Al- Naamania salt Basin north western

Abstract

The influence of physical and chemical parameters on the abundance and diversity of Mosquito Species were studied in Al- Naamania Salt Basin North Western Al-kut City during a period of seven months (October 2012- April 2013).Three species belong to three genera of Culicidae were identified from a total of (339) larvae: Aedes caspius (Pallas) (66.o7%) was the most abundant during the period of the study,Culex pipiens (Linnaeus) (18.58%) and Culiseta longiareolata (Macquarrt) (10.02%) .During this study, some of Physicochemicals parameters, such as water pH, Total Dissolved Solids (TDS), water temperatur , water salinity (NaCl), Electrical conductivity (EC) were measured. The results from Statistical analysis showed that Aedes caspius has significant positive correlation with EC (P>0.001) and positive correlation but not significant with NaCl, TDS, PH and temperature. Culex pipiens has negative correlation not significant with EC, NaCl, TDS, PH and temperature. Finally Culiseta longiareolata has negative significant correlation with EC, PH (p>0.05) and temperature (p>0.01) also its has negative correlation but not significant with NaCl and TDS. According to principal component analysis (PCA) there are no relationships between the species themselves.
