Resumo: Aedes albopictus, the Asian tiger mosquito, continues exp-ing its geographic range - involvement in mosquito-borne diseases such as chikungunya - dengue. Vector control programs rarely attempt to suppress this diurnal species with an ultra-low volume (ULV) adulticide because for maximum efficacy applications are conducted at night. During 2009-2011 we performed experimental nighttime applications of a novel adulticide (DUET®) against field populations of Ae. albopictus within an urban site composed of approximately 1,000 parcels (home - yard) in northeastern USA. Dual applications at mid label rate of the adulticide spaced one or two days apart accomplished significantly higher control (85.0 ± 5.4% average reduction) than single full rate applications (73.0 ± 5.4%). Our results demonstrate that nighttime ULV adulticiding is effective in reducing Ae. albopictus abundance - highlight its potential for use as part of integrated pest management programs - during disease epidemics when reducing human illness is of paramount importance.
