Seasonal distribution and diel biting patterns of culicine mosquitoes in Costa Marques, Rondônia, Brazil.
A study of peridomestic man-biting culicines in the Amazon Basin was conducted from January through December, 1987. Fifteen species of mosquitoes from six genera were collected by volunteers in all-night human-bait indoor and outdoor collections at five houses in and near the town of Costa Marques, Rondônia, Brazil. Culex quinquefasciatus and members of the Mansonia titillans/indubitans Group comprised 61 and 33%, respectively, of all culicines collected from human-bait outside houses and 62 and 35%, respectively, of those collected from volunteers inside houses in the town. In rural areas, Cx. quinquefasciatus was less abundant and only comprised 2 and 5% of the culicines, respectively, collected inside and outside houses. Mansonia titillans/indubitans Group comprised 75% and 86% of the culicines collected inside and outside houses, respectively, from rural residences. Culex quinquefasciatus and members of the Mn. titillans/indubitans Group were more endophilic than other culicines collected. Nocturnal and seasonal biting rhythms for the more common culicines are described.
