Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>From 2003 to 2007, entomological surveys were conducted in Lobito town (Benguela Province, Angola) to determine which <italic>Anopheles</italic> species were present and to identify the vectors responsible for malaria transmission in areas where workers of the Sonamet Company live. Two types of surveys were conducted: (1) time and space surveys in the low and upper parts of Lobito during the rainy and dry periods; (2) a two‐year longitudinal study in Sonamet workers' houses provided with long‐lasting insecticide‐treated nets (LLIN), "PermaNet, " along with the neighboring community. Both species, <italic>An. coluzzii</italic> (M molecular form) and <italic>An. gambiae</italic> (S molecular form), were collected. <italic>Anopheles coluzzii</italic> was predominant during the dry season in the low part of Lobito where larvae develop in natural ponds and temporary pools. However, during the rainy season, <italic>An. gambiae</italic> was found in higher proportions in the upper part of the town where larvae were collected in domestic water tanks built near houses. <italic>Anopheles melas</italic> and <italic>An. listeri</italic> were captured in higher numbers during the dry season and in the low part of Lobito where larvae develop in stagnant brackish water pools. The infectivity rates of <italic>An. gambiae</italic> s.l. varied from 0.90% to 3.41%.</p> </abstract>
