Abstract
The present work aimed at studying certain ecological factors influencing the distribution and abundance of mosquito larvae in two localities in Cairo Governorate, representing different levels of urban planning: El-Muqattam representing planned safe and planned unsafe area and Abu-Seir representing unplanned unsafe area.
The study areas were detected on IKONOS satellite imagery. A geographic information system (GIS) was used to overlay measured grids,
which served as a sampling frame. Water bodies in the selected grid cells were identified and characterized based on physical (perimeter, water
movement, exposure to sunlight, water depth, type of the bottom and presence of solid wastes), biological (algae, plants and predators) and
physico-chemical (temperature, pH, salinity, turbidity, dissolved oxygen,and nitrite) parameters. These were surveyed for mosquito larvae over a 17 month period. Following is a summery of the obtained results:
1. MOSQUITO SPECIES COMPOSITION
Six mosquito species (5 culicine and one anopheline) were collected from the two localities. These were Culex pipiens, Cx. perexiguus, Cx.
pusillus, Ochlerotatus caspius, Culiseta longiareolata and Anopheles multicolor. In El-Muqattam (M), all species except Cx. pusillus were collected; while in Abu-Seir (A), only Cx. pipiens, Cx. perexiguus, Cx.
pusillus and Oc. caspius were collected.
