Ae. aegypti was the most predominant species in the urban area of Chittagong city, while in the rural environment of Chittagong University campus Ae. albopictus appeared to be the pre-dominant. Ae. albopictus was 63.2% among the total indoor day-resting adult mosquitoes in CU campus, whereas in the city in similar collection, Ae. aegypti was predominant with 50% of the total population.
