Survey of Aedes albopictus (Skuse) in a residential area in Yokohama and its control

Abstract

The larval control of mosquitoes was carried out by community participation in a residential area in Yokohama. Simultaneously, a biological survey of mosquito occurrence was carried out to efficiently promote control. The survey has definitely shown that the target species should be only Aedes albopictus (Skuse) and that the abundant catch basins scattered along the roadside were the most important breeding places. Catch basins and some other minor breeding places were treated using 0.5% pyriproxyfen tablets by the community, every month from May to September for 8 years from 2005. As a result, the biting density dropped from 20 to 2～4 (m/h). According to questionnaire responses, the inhabitants highly valued the effect.
