Abstract:

Understanding the distribution of Anopheles species is essential for planning and implementing malaria control programmes. This study assessed the composition and distribution of cryptic species of the main malaria vector, the Anopheles gambiae complex, in different districts of Kinshasa. Anopheles were sampled using CDC light traps in the four Kinshasa districts between July 2021 and June 2022, and then morphologically identified. Equal proportions of Anopheles gambiae s.l. per site were subjected to polymerase chain reaction to identify the cryptic species of the Anopheles gambiae complex. A

Abstract:

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 Ethiopian species is named Anopheles amharicus Hunt, Wilkerson & Coetzee sp. n., based on chromosomal, cross-mating and molecular evidence.

Abstract:

The ability of Anopheles gambiae complex mosquitoes to transmit Plasmodium infection is known to be variable within sibling species of the complex with strains that cannot transmit the parasite. High sporozoite infection rate recorded showed that A. gambiae mosquitoes are potent malaria vectors in southwestern Nigeria. The aim of this study was to identify the infective and refractory strains of A. gambiae mosquitoes and to determine the sporozoite infection rate in this area. The infective strains were A. gambiae (sensu stricto) and A. arabiensis, while the refractory strains were A. gambiae

Anopheles gambiae are a complex consisting of eight morphologically indistinguishable species and each of the members of the complex having unique biology, ecology and behaviour and should be studied and differentiated.

This assumption of monophyly has been generally validated by independent data.

Extract of different concentrations were evaluated at the level of 2.00 3.00, 4.00, 5.00 and 0.00 (Control) mg/ml. Distilled water only was used as control. Twenty (20) larvae were put into four (4) cups containing 100ml of the test solution of each concentration. Larval to pupa mortality were recorded and calculated after 24, 48 and 72h after treatment.

Abstract:

Baseline data on the distribution and genetic variability of malaria vector species are key to effective malaria control in endemic areas. This study characterised Anopheles gambiae s.l. and their preferred blood-meal hosts in the Southern Part of Gombe State using polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) probing, respectively. The overall results from the226 An gambiae s.l populations revealed the predominance of An. coluzzii 68 (51.13%) followed by An. gambiae s. s. 61 (45.86%), while the least was An. 2 arabiensis 4 (3.11%).

Abstract:

A better understanding of malaria transmission at a local scale is essential for developing and implementing effective control strategies. In the framework of a randomized controlled trial (RCT), we aimed to provide an updated description of malaria transmission in the Korhogo area, northern Côte d’Ivoire, and to obtain baseline data for the trial. We performed human landing collections (HLCs) in 26 villages in the Korhogo area during the rainy season (September–October 2016, April–May 2017) and the dry season (November–December 2016, February–March 2017).

Abstract:

It has been established that Anopheles gambiae complex sibling species are the major Plasmodium malaria vectors in Africa; however, not all the sibling species transmit the infection. Easier molecular methods, PCR-based assays, have been developed to distinguish the several members of the A. gambiae complex. However, malaria vector research in less developed countries, particularly sub-Saharan Africa, is being hampered by the lack of PCR facilities in laboratories and the cost of carrying out the assay within lack of funding. Hence, the present study was designed to develop a simple identifica

Abstract:

Malaria remains a major health concern in the tropics with its vector; the Anopheles species assume several dimensions of resisting control measures. Molecular characterization of the malaria vectors was carried out in two locations of the Federal Capital Territory, Abuja Nigeria. Indoor and outdoor biting mosquitoes were collected and identified morphologically. A total of two hundred and twenty-eight (228) Anopheles mosquitoes were caught from two communities (Kubwa and Nyanya).

Abstract:

Abstract The African Anopheles gambzae complex of six sibling species has many polymorphic and fixed paracentric inversions detectable in polytene chromosomes. These have been used to infer phylogenetic relationships as classically done with Drosophila. Two species, A. gambiae and A. merus, were thought to be sister taxa based on a shared X inversion designated Xag. Recent DNA data have conflicted with this phylogenetic inference as they have supported a sister taxa relationship of A. gambiaeand A. arabiensis. A possible explanation is that the Xag is not monophyletic. Here we present data fro

Our analysis placed the new taxon in the phylogenetic tree of the An. gambiae complex, revealing important introgression events with other members of the complex.
