| Abstract | ||||
| The present study aimed to study Culex mosquito vectors' different patterns in Alexandria Governorate, Egypt. Four regions (Abis, Al Mamurah, El Ibrahimeya and El-Agamy) are selected for this study. Different physicochemical parameters and breeding water (temperature, pH, total dissolved solids, and dissolved oxygen) were measured; the relationship between measured parameters and the relative abundance of mosquito larvae were examined. Data revealed that Culex mosquito species in Alexandria Governorate were represented by four species: Cx. pipiens, Cx. antennatus, Cx. theileri and Cx. tritaeniorhynchus. Culex pipiens and Cx. antennatus were the most abundant mosquito species in the study area. The highest relative abundance of Cx. pipiens larvae were recorded in El Ibrahimeya region (56.19%). A significant variation (P<0.05) was detected between investigated species in their abundance during the study period, except Cx. tritaeniorhynchus and Cx. theileri, where there was no significant variation (P>0.05) in their abundance, compared to each other. In addition, a significant variation (P< 0.05) was recorded between Abis comparison to Al Mamurah, El Ibrahimeya, and El-Agamy. On the other hand, the temperature was the most reliable factor affecting the abundance of all species at Abis, Al Mamurah and El-Agamy, while the total dissolved solids (TDS) represented a reliable factor for the abundance of all species at El-Agamy. Furthermore, all species abundance at El Ibrahimeya is associated with dissolved oxygen (DO). | ||||
