The prevalence of mosquitoes was studied in two forest parks (Mt. Enkaizan, and Jingashita) in Yokohama City using a sweeping net and a light trap with dry ice. A total of 342 (245) adults of 5 species in 4 genera were collected by sweeping in Enkaizan (Jingashita) in 2010. In 2011, a total of 399 adults of 4 species and 738 adults of 3 species in 2 genera were collected respectively in Enkaizan and Jingashita. Aedes albopictus predominated throughout the investigation. In Jingashita park, a total of 340 adults of 8 species and 5 genera were collected by light trap with dry ice in 2010; 484 adults of 7 species and 4 genera were collected there by light trap with dry ice in 2011. Ae. albopictus and Tripteroides bambusa were dominant among species captured in Jingashita park in 2010 and 2011 by light trap. In Enkaizan, Ae. albopictus was abundant in the residential area. The correlation line fitted well to the relationship between the distance from the residential area and the number of Ae. albopictus with coefficients of determination of -0.670 in 2011, -0.694 in 2011. The sweeping method was convenient for investigating several points in a short time, and suitable for surveying mosquitos like Ae. albopictus with restricted spatial distributions of host-seeking.
