BACKGROUND A study was carried out in a village of the mainland region of Equatorial Guinea in order to ascertain a) which members of Anopheles gambiae complex could be involved in malaria transmission and b) the rate of infectivity for Anopheles melas comparing two different methods, a PCR able to detect sporozoite-DNA and an immunochromatographic assay… (More)
BACKGROUND Malaria transmission varies from one country to another and there are also local differences in time and space. An important variable when explaining the variability in transmission is the breeding behaviour of the different vector species and the availability of breeding sites. The aim of this study was to determine the geographical variability… (More)
OBJECTIVES To determine the frequency of knockdown resistance (kdr) mutations in the malaria vector Anopheles gambiae s.s. from continental Equatorial Guinea; and to relate kdr genotypes with susceptibility to DDT and pyrethroid insecticides in this vector. METHODS Female mosquitoes were collected in two villages, Miyobo and Ngonamanga, of mainland… (More)
BACKGROUND Malaria transmission in Equatorial Guinea and its space-time variability has been widely studied, but there is not much information about the transmission of malaria on the small island of Annobon. In 2004, two transversal studies were carried out to establish the malaria transmission pattern on Annobon and analyse the circulating Plasmodium… (More)
Anopheles (Cellia) carnevalei is described in the mainland region (Río Muni) of Equatorial Guinea. Anophelines collected were identical to An. nili with exception of some morphological characters found in wings, head, and legs.
This is the first description of 3rd and 4th instars of Anopheles (Cellia) carnevalei. Adults were caught in the mainland region (Rio Muni) of Equatorial Guinea. Larvae present characteristic palmate setae different from Anopheles nili.
