Abstract:
A descriptive cross- sectional study was carried in Port Sudan city
in its three sectors which included eight districts during February to June
2011.The study was conducted to determine the type of existing
mosquitoes and their distribution in Port Sudan city. 500 samples of
mosquitoes were collected; adults were collected from rooms in houses
and larvae from Zeirs, generator water tank, marshes and leakage water.
Some of the larvae were placed in cages to complete their life cycle and
reach the adult stage for further identification. The result revealed that the
three genera of mosquitoes found in the city were Culex ( 60.2%), Aedes
(33.2%) and Anopheles (6.6%.) .The species encountered in the city were
Cx. quinquefasciatus (46%), Cx. sitiens(14.2%), Ae. aegypti (33.2%) and
An. funestus (6.6%). Also, the study revealed that in the eastern sector,
only Cx. quinquefasciatus (16.6%) and Ae. aegypti (13%) were found.
The middle sector has the high rate of An. funestus (5%) and Cx. sitiens
(14.2%), but Cx. quinquefasciatus and Ae. aegypyi constituted 9.4% and 11.8% respectively. In the southern sector, An. funestus represented
1.6%, Cx. quinquefasciatus (20%) and Ae. aegypti (8.4%). When the
mosquitoes were classified according to gender, Cx. quinquefasciatus
males constituted 60.4% while the females constituted 39.6% of the total
collection. For Cx. sitiens, the males and females constituted 70.4% and
29.2% respectively. Ae. aegypyi males constituted 39.1%, while the
,females represented the highest rate collected (60.9%). For An. funestus,the
males constituted 42.4% while the females constituted 57.6%
