title: Indoor and outdoor host-seeking rhythms of Anopheles albitarsis (Diptera: Culicidae) in Trinidad, West Indies.
abstract: The diel host-seeking periodicity of Anopheles (Nyssorhynchus) albitarsis Lynch-Arribalzaga (sensu latu) was monitored on humans during a period of 6 mo in Frederick Settlement, County Caroni, Trinidad, West Indies. Similar abundances and periodicities were recorded at indoor and outdoor sites, with peak host-seeking occurring at 1900 hours. Only 78 An. albitarsis females were collected resting indoors, indicating that most females rest outdoors and, therefore, may escape contact with residual insecticides applied on wall surfaces.
