Two new species within the Anopheles gambiae complex are here described and named. Based on molecular and bionomical evidence, the An. gambiae molecular "M form" is named Anopheles coluzzii Coetzee & Wilkerson sp. n., while the "S form" retains the nominotypical name Anopheles gambiae Giles. Anopheles quadriannulatus is retained for the southern African populations of this species, while the Et...

We report the identification of genomic sequences in various anopheline mosquitoes (family Culicidae: suborder Nematocera: order Diptera) showing homology to the class II, short inverted-terminal-repeat (ITR) transposable element P from Drosophila melanogaster (family Drosophilidae; suborder Brachycera: order Diptera). Anopheles gambiae appears to have at least six distinct P elements. Other an...

BACKGROUND & OBJECTIVES Correct vector identification is an important task in the planning and implementation of malaria vector control programmes. This study was designed to provide baseline information on the species composition and distribution of members of the Anopheles gambiae complex in three eco-vegetational zones in Bayelsa state, Nigeria. METHODS Adult mosquitoes were collected by p...

The G-3 strain of Anopheles gambiae was compared with 2 other strains of An. gambiae and An. freeborni, An. stephensi, and An. dirus for susceptibility to infection with 7 different geographic strains of Plasmodium vivax. Ratios of infection varied, indicating that certain strains of P. vivax were more infectious to the G-3 strain of An. gambiae than to other anopheline species/strains. Based o...

Insect symbionts have the potential to block the transmission of Background vector-borne diseases by their hosts. The advancement of a symbiont-based transmission blocking strategy for malaria requires the identification and study of symbionts. Anopheles : High throughput 16S amplicon sequencing was used to profile the Methods bacteria associated with and identify potential Anopheles gambiae se...

This study was carried out between May and October, 2010 to morphologically identify Anopheles species in parts of Kano State. A total of 2374 Anopheles were collected and identified. 1782 (75.07%) were collected from Nassarawa Local Government Area while 592 (24.93%) were collected from Tarauni Local Government Area. Using Anopheles characters of Gilles and Coetzee (1987) under zeiss light mic...

Wolbachia pipientis are maternally inherited endosymbionts associated with cytoplasmic incompatibility, a potential mechanism to drive transgenic traits into Anopheles populations for malaria control. W. pipientis infections are common in many mosquito genera but have never been observed in any Anopheles species, leading to the hypothesis that Anopheles mosquitoes are incapable of harboring inf...

Background: Insect symbionts have the potential to block the transmission of vector-borne diseases by their hosts. The advancement of a symbiont-based transmission blocking strategy for malaria requires the identification and study of Anopheles symbionts. Methods: High throughput 16S amplicon sequencing was used to profile the bacteria associated with Anopheles gambiae sensu lato and identify p...

Whole genome sequencing of disease vectors such as Aedes aegypti, Anopheles gambiae, and recently Anopheles funestus are enabling scientists to identify and investigate regions involved in the genetic plasticity of these vectors in order to formulate new disease control strategies. In the current study, sequence data from a single Anopheles funestus BAC clone is examined in order to predict and...
