Abstract EN
The distribution and monthly abundance of mosquito larvae in released water, drainage canals and sewage water tanks in Ismailia governorate were investigated.
The results obtained indicated the presence of five culicine (Culex.
pipiens, Cx.
pusillus, Cx.
perexiguus, Cx.
theleri and Ochlerotatus.
caspius) and two anopheline (Anopheles.
multicolor and An.
pharoensis) mosquito species.
Significantly higher larval density was recorded in sewage water (n= 5534; 46.08%) as compared with released water (n= 2903; 24.17%) and drainage water (n= 3573; 29.75%).
Culex pipiens was the most dominant mosquito species in the three habitats.
The effects of environmental parameters including pH, biological and chemical oxygen demands, day time water temperature, plant growth, salinity, total organic matter and concentrations of heavy metals on larval population density were investigated.
The positive correlations observed between heavy metals concentrations in the three habitats suggested relative uniformity of the sources of metal pollutants.
Culex pipiens larvae demonstrated high tolerance to elevated levels of heavy metals in sewage water and compensatory effects of high nutrient levels generally associated with sewage or domestic waste.
High densities of culicine larvae were accompanied by low density of anopheline larvae.
This was attributed to water chemistry & competitive interactions.
