The research has been conducted which aims to get the characteristics of population density imago Aedes aegypty and Aedes albopictus in Kotamobagu, based on the distribution of time and height from the sea level; to get population density of adult Aedes aegypty and Aedes albopictus captured in indoor and outdoor based on time distribution. The research consists of four phases, i.e. the first phase of determining the location of sampling based on the existence of cases of dengue fever in the city, the second stage of sampling third stage larva, imago capture Aedes aegypti and Aedes albopictus inside and out and a fourth stage of data analysis research. The results showed that the average population density of Aedes aegypti and Aedes albopictus highest, according to time span found on 08.00-10.00 in the morning and 14.00-16.00 in the afternoon. The average population density of Aedes aegyti outdoors highest found in the sample location in South Minahasa. While the average population density outside the lowest found at the location of the sample of Talaud. In contrast to population density, population density outdoors only once showed the highest population density in the s/d at 15.00 16.00 Wita. The peak of population density of Aedes albopictus in the highest room discovered in South Minahasa sample locations while the lowest on a population sample of Talaud. The highest population density peak at 12 noon: whereas the lowest sample location on the Talaud Islands. In contrast to the density of the population of Aedes aegypti in the room which has 2 peaks of the highest population density number of individuals with relatively the same mosquito, Aedes albopictus on only one of the highest population density according to the peak hours.  Inversely proportional to the density of population of a. aegypti, a. albopictus more found outside the room. The highest population density is found in the city of Manado and Kotamobagu whereas the lowest was found in Talaud Islands.

Key words: Aedes albopictus, Aedes aegypti, population, density, Northern Sulawesi
