![]() A GIS analysis of geographic and socio-economic parameters revealed that An. Anopheles sergentii fed on cattle (67.3 %) and humans (48.3 20.7 % mixed both species), but only 14.7 % were found in PKDs, indicating predominantly exophilic behaviour. arabiensis was predominantly anthropophilic (human blood index = 0.86) with an entomological inoculation rate of 1.58 infective bites/person/year. A vector in both wet and dry seasons, An. ![]() algeriensis, incriminating both species as malaria vectors for the first time in Yemen. sergentii (2/295) and a single female of An. Plasmodium falciparum sporozoites were detected in An. vivax) confirming this species as the primary malaria vector in Yemen. ELISA detected Plasmodium sporozoites in 0.9 % of 2921 An. azaniae, the typical form and a previously unrecognized form not immediately identifiable as An. Sequences for the standard barcode region of the mitochondrial COI gene confirmed the presence of two morphological forms of An. Seven Anopheles species were identified among 3407 anophelines collected indoors using light traps (LT) and pyrethrum knockdown catches (PKD): Anopheles arabiensis (86.9 %), An. With one exception, Plasmodium malariae, all infections were P. Cross-sectional blood film surveys recorded an overall malaria infection rate of 15.3 % (250/1638), with highest rates exceeding 30 % in one village in May and December 2005.
